ant/WHATSNEW

Changes from Ant 1.8.0 TO current SVN version
=============================================

Changes that could break older environments:
-------------------------------------------

Fixed bugs:
-----------

 * Tasks that iterate over task or type definitions, references or
   targets now iterate over copies instead of the live maps to avoid
   ConcurrentModificationExceptions if another thread changes the
   maps.
   Bugzilla Report 48310.

 * The filesmatch condition threw a NullPointerException when
   comparing text files and the second file contained fewer lines than
   the first one.
   Bugzilla Report 48715.

 * Regression: The <ear> task would allow multiple
   META-INF/application.xml files to be added.
   Bugzilla Report 6836.

Other changes:
--------------

 * Project provides new get methods that return copies instead of the
   live maps of task and type definitions, references and targets.

Changes from Ant 1.8.0RC1 TO Ant 1.8.0
======================================

Changes that could break older environments:
-------------------------------------------

 * the appendtolines filter has been renamed to suffixlines.

Fixed bugs:
-----------

 * stack traces were not reported at all by <junit/>
   when filtertrace="on", which is the default.

 * ant.bat can now also process the -noclasspath switch when it is 
   the first switch on a command line.
   Bugzilla Report 48186.

 * <fixcrlf> now tries to delete the created temporary files earlier.
   Bugzilla Report 48506.

 * the implementation of <zip> had been changed in a way that broke
   the jarjar links task and protentially other third-party subclasses
   as well.
   Bugzilla Report 48541.
   
 * <scp> task didn't report build file location when a remote operation failed
   Bugzilla Report 48578.  

 * <propertyfile> would add the same comment and a date line each time
   it updated an existing property file.
   Bugzilla Report 48558.

 * <sound> didn't work properly in recent Java VMs.
   Bugzilla Report 48637.

Changes from Ant 1.7.1 TO Ant 1.8.0RC1
======================================

Changes that could break older environments:
-------------------------------------------

 * if and unless attributes (on <target> as well as various tasks and other
   elements) have long permitted ${property} interpolation. Now, if the result
   evaluates to "true" or "false" (or "yes", "no", "on", "off"), that boolean
   value will be used; otherwise the traditional behavior of treating the value
   as a property name (defined ~ true, undefined ~ false) is used. Existing
   scripts could be broken if they perversely defined a property named "false"
   and expected if="false" to be true, or used if="true" expecting this to be
   triggered only if a property named "true" were defined.

 * Ant now requires Java 1.4 or later.

 * Improved handling of InterruptException (lets suppose someone/thing
   is trying to kill the thread when we receive an
   InterruptException), when an InterruptException is received, we do
   not wait anymore in a while loop till the end time has been
   reached.
   Bugzilla Report 42924.

 * Refactor PropertyHelper and introspection APIs to make extension
   more granular and support setting task/type attribute values to
   objects decoded by custom PropertyEvaluator delegates. Also add
   <propertyhelper> task for registering delegates and/or replacing
   the registered PropertyHelper instance.
   Bugzilla Report 42736.

 * Added a restricted form of typedef called <componentdef>. This
   allows definition of elements that can only be within tasks or
   types. This method is now used to define conditions, selectors,
   comparators and filterreaders. This means that tasks may now have
   nested conditions just by implementing the Condition interface,
   rather than extending ConditionBase. It also means that the use of
   namespaces for some of the selectors introduced in Ant 1.7.0 is no
   longer necessary.  Implementing this means that the DynamicElement
   work-around introduced in Ant 1.7.0 has been removed.
   Bugzilla Report 40511.

 * In the <touch> task when a <mapper> is used, the millis and
   datetime attributes now override the time of the source resource if
   provisioned.
   Bugzilla Report 43235.

 * Remove fall-back mechanism for references that are not resolved
   during normal runtime execution.

 * FileUtils.createTempFile now actually creates the file.
   The TempFile task still does not create the file by default, can be
   instructed to do so however using a new parameter.
   Bugzilla Report 33969.
  
 * A lock in Project ensured that a BuildListener's messageLogged
   method was only ever executed by a single thread at a time, while
   all other methods could be invoked by multiple threads
   simultaniously (while within <parallel>, for example).  This lock
   is no longer in place, messageLogged should be made thread-safe
   now.

 * <sql>'s onError="stop" no longer fails the build if an error
   occurs,  this is the main difference between stop and error and
   matches what the documentation implied.
   Bugzilla Report 24668.

 * Ant's configuration introspection mechanisms have been modified to prefer
   Resource and FileProvider attributes to plain java.io.File attributes;
   however the configuration-from-String behavior remains equivalent, rendering
   a FileResource.

 * CBZip2InputStream will now throw an IOException if
   passed in a null or empty InputStream to read from.
   Bugzilla Reports 32200.

 * <unzip> will now fail when trying to extract certain broken
   archives that would have been silently ignored in earlier version.
   Bugzilla Report 35000.

 * Ant's <zip> family of tasks tries to preserve the existing Unix
   permissions when updating archives or copying entries from one
   archive to another.
   Since not all archiving tools support storing Unix permissions in
   the same way that is used by Ant, sometimes the permissions read by
   Ant seem to be 0, which means nobody is allowed to do anything to
   the file or directory.
   If Ant now encounters a permission set of 0 it will assume that
   this is not the intended value and instead apply its own default
   values.  Ant used to create entries with 0 permissions itself.
   The <zip> family of tasks has a new attribute preserve0permissions
   that can be set to restore the old behavior.
   Bugzilla Report 42122.

 * If a batch containing multiple JUnit tests running inside a forked
   Java VM caused the VM to crash (or caused a timeout), the
   formatters would receive an error message for the last test in the
   batch.
   Ant will now pass in a test with the name "Batch-With-Multiple-Tests"
   instead - this is supposed to show more clearly that the last test
   may not have started at all.
   Bugzilla Report 45227.

 * If the number of minutes a build takes is bigger then 1000 Ant will
   no longer print a thousands separator in the "elapsed time"
   message.  It used to be the thousands separator of the current
   locale.
   Bugzilla Report 44659.

 * <symlink action="delete"> used to fail if the link was broken (i.e.
   pointing to a file or directory that no longer existed).  It will now
   silently try to remove the link.
   Bugzilla Report 41285.

 * <delete file="..."> used to log a warning and not delete broken
   symbolic links.  <delete dir="..."/> didn't even log a warning.
   The task will now try to delete them in both cases.
   Bugzilla Report 41285.

 * if the dir attribute of a <fileset> points to a symbolic link and
   followsymlinks is set to false, the fileset will no longer be
   scanned and always seem empty.
   Bugzilla Report 45741.

 * the .NET tasks that have been deprecated since Ant 1.7.0 have been
   removed, please use the stand-alone Antlib you can find at
   http://ant.apache.org/antlibs/dotnet/index.html
   instead.

 * the logic of closing streams connected to forked processes (read
   the input and output of <exec> and friends) has been changed to
   deal with cases where child processes of the forked processes live
   longer than their parents and keep Ant from exiting.
   It is unlikely but possible that the changed logic breaks stream
   handling on certain Java VMs.
   Bugzilla issue 5003.

 * <checksum>'s totalproperty was platform dependent because it relied
   on java.io.File#compareTo.  It has now been made platform
   independent, which means that totalPropery values obtained on
   Windows (and other systems where the sort order of File is not case
   sensitive) can be different from the values obtained with earlier
   versions of Ant.
   Bugzilla Report 36748.

 * globmapper didn't work properly if the "to" or "from" patterns
   didn't contain a "*".  In particular it implicitly added a * to the
   end of the pattern(s).  This is no longer the case.  If you relied
   on this behavior you will now need to explicitly specify the
   trailing "*".
   Bugzilla Report 46506.

 * <copy> silently ignored missing resources even with
   failOnError="true".  If your build tries to copy non-existant
   resources and you relied on this behavior you must now explicitly
   set failOnError to false.
   Bugzilla Report 47362.

 * Ant now prefers the java.runtime.version system property over
   java.vm.version for the Created-By Manifest attribute.
   Bugzilla Report 47632.

 * The <image> task now supports a nested mapper.  In order to
   implement this, the Java API of the task had to change so any
   custom subclass overriding the processFile method will need to
   adapt (by overriding the new two-arg processFile method).
   Bugzilla Report 23243.

 * A new property syntax can be used to set attributes from
   references: ${ant.ref:some-reference}

   In most cases this will yield the exact same result as 
   ${toString:some-reference} - only when an attribute setter method
   accepts an object type other than string and the project's
   reference is an Object of matching type the new syntax will pass in
   that object.

   If your build file already contains properties whose name starts
   with "ant.ref:" there is a potential for collision.  If your
   property has been set, normal property expansion will take
   precedence over the new syntax.  If the property has not been set
   and a reference with the postfix of your property name exists
   (i.e. in a very unlikely event) then the new syntax would yield a
   different result (an expanded property) than Ant 1.7.1 did.

 * A ProjectHelper implementation can now provide the default build file
   name it is expecting, and can specify if they can support a specific build
   file. So Ant is now capable of supporting several ProjectHelper
   implementations, deciding on which to use depending of the input build file.

 * Mapper-aware selectors (depends, different, present) now accept typedef'd
   FileNameMappers.

Fixed bugs:
-----------

 * The default logger was failing to print complete stack traces for
   exceptions other than BuildException when inside <ant> or
   <antcall>, thus omitting often important diagnostic
   information.
   Bugzilla 43398 (continued).

 * Better handling of package-info.class.
   Bugzilla Report 43114.

 * RPM task needed an inserted space between the define and the value.

 * <symlink> task couldn't overwrite files that were in the way of the symlink.
   Bugzilla Report 43426.

   within messageLogged while a different thread also accessed one.
   Bugzilla Report 45194

 * Handle null result of system getProperty() in CommandlineJava.
   Similar to Bugzilla Report 42334.

 * Length task did not process nonexistent Resources even though these might
   conceivably still carry file length information.
   Bugzilla Report 45271.

 * <javac>'s includeJavaRuntime="false" should work for gcj now.  Note
   that you may need to set includeAntRuntime to false in order to
   have full control.
   Bugzilla Report 34638.

 * <sql> would fail if the executed statment didn't return a result
   set with some JDBC driver that dissalow Statement.getResultSet to
   be called in such a situation.
   Bugzilla Report 36265 

 * if the executed statement in <sql> returned a result set and an
   update count, the count would be lost.

   Bugzilla Report 44226.
   
 * failures were treated as errors in forked JUnit tests when JUnit 4
   was used.
   Bugzilla Report 43892.

 * <jar> and <manifest> disallowed manifest attributes whose name
   contained the character '8'.
   Bugzilla Report 45675.

 * BigProjectLogger would set the project's basedir to the current
   working directory.
   Bugzilla Report 45607.

 * only <formatter>s that logged to a file were notified if forked VM
   crashed or a timeout occured in <junit>.
   Bugzilla Report 37312.

 * ant -v -version would print the version information twice.
   Bugzilla Report 45695.

 * when nested into builds that have been invoked by <ant> tasks
   <subant> might set the wrong basedir on the called projects.
   Bugzilla Report 30569.

 * If the message of the failed assertion of a forked JUnit test
   contained line feeds some excess output ended up in Ant's log.
   Bugzilla Report 45411.

 * <symlink action="delete"> failed to delete a link that pointed to
   a parent directory.
   Bugzilla Report 45743.

 * <symlink action="delete"> failed if ant lacked permission to rename

   Bugzilla Report 41525.

 * when checking whether a jar is signed, <signjar> ignored the
   sigfile attribute.
   Bugzilla Report 44805.

 * When using JavaMail all <mail> tasks used the same mail host
   regardless of their configuration.

   find the corresponding source files.
   Bugzilla Report 45916.

 * <javadoc> failed if the nested <bottom> or <head> contained line
   breaks.

   worked if JavaMail was available.
   Bugzilla Report 42389.

 * MailLogger could cause a NullPointerException.
   Bugzilla Report 44009.

 * <junit> didn't recognize failed assertions as failures if they
   caused subclasses of AssertionError to be thrown (like

   fails).
   Bugzilla Report 45028.

 * the Unix "ant" wrapper script failed to protect wildcards in

 * if an error occurs while logging the buildFinished event, the
   original error is now logged to System.err.
   Bugzilla Report 25086.

 * <copy> failed with a NullPointerException when copying a resource
   without a name.  It will now fail with a meaningful error message.

   using TraX) before falling back to Ant's own classpath.
   Bugzilla Report 46172.

 * <dependset> complained about files being modified in the future if
   they had been just very recently (within Ant's assumed granularity

   Bugzilla Report 43665.

 * <sshexec> didn't store the ouput in outputproperty if the remote
   command failed.
   Bugzilla Report 46340.

 * DirectoryScanner's slow-scanning algorithm that is used when you
   ask for excluded or not-included files and/or directories could
   miss some files and directories in the presence of recursive
   exclude patterns.

 * <sort> resource collection kept only one of entries deemed equal by
   the chosen Comparator.
   Bugzilla Report 46527.

 * the ZipFile class used by <unzip> and others could leave the
   archive open (making it undeletable on Windows as long as the java
   VM was running) for files with an unexpected internal structure.
   Bugzilla Report 46559.

 * The zip package now supports the extra fields invented by InfoZIP
   in order to store Unicode file names and comments.

 * The zip package detects the encoding bit set by more modern
   archivers when they write UTF-8 filenames and optionally sets it
   when writing zips or jars.
   Bugzilla Report 45548

 * <sync> could run into a NullPointerException when faced with broken
   symbolic links.
   Bugzilla Report 46747.

 * <signjar> has a new force attribute that allows re-signing of jars
   that are already signed.
   Bugzilla Report 46891.

 * <sshexec> now again honors failonerror in the face of connection
   errors.
   Bugzilla Report 46829.

 * The <replacetokens> filter threw an exception if the stream to
   filter ended with a begin token.
   Bugzilla Report 47306.

 * <scriptmapper>, <scriptfilter> and <scriptcondition> didn't support
   the setbeans attribute.
   Bugzilla Report 47336.

 * <loadproperties>' encoding attribute didn't work.
   Bugzilla Report 47382.

 * Ant created tar archives could contain random bytes at the end
   which confused some untar implementations.
   Bugzilla Report 47421.

 * various places where unchecked PrintWriters could hide exceptions
   have been revisited to now check the error status or not use a
   PrintWriter at all.
   Bugzilla Report 43537.

 * filesetmanifest="mergewithoutmain" in <jar> didn't treat inline
   manifests as expected.
   Bugzilla Report 29731.

 * <record> didn't work properly with nested builds.
   Bugzilla Report 41368. 

 * <jar> with filesetmanifest different from skip didn't work if the
   update attribute has been set to true.
   Bugzilla Report 30751.

 * The default stylesheets for <junitreport> failed to properly escape
   XML content in exception stack traces.
   Bugzilla Report 39492.

 * AntClassLoader didn't set the proper CodeSource for loaded classes.
   Bugzilla Report 20174.

 * AntClassLoader.getResourceAsStream would return streams to
   resources it didn't return with getResource and to classes it
   failed to load.
   Bugzilla Report 44103.

 * Logging exceptions without a message would cause a
   NullPointerException.
   Bugzilla Report 47623.

 * WeblogicDeploymentTool could fail on platforms with a file
   separator other than "/".
   Bugzilla Report 35649.

 * The update attribute of the modified selector was ignored.
   Bugzilla Report 32597.

 * <manifest> and <jar> can now merge Class-Path attributes from
   multiple sources and optionally flatten them into a single
   attribute.
   The default behaviour still is to keep multiple Class-Path
   attributes if they have been specified and to only include the
   attributes of the last merged manifest.
   Bugzilla Report 39655.

 * <delete> didn't work correctly with a <modified> selector because
   it was scanning the same filesets more than once.
   Bugzilla Report 43574.

 * when using custom filterreaders with the <filterreader classname="">
   syntax Ant could leak memory.
   The problem didn't occur when using <typedef> or <componentdef> to
   define the filterreader which is the recommended approach.
   Bugzilla Report 45439.

 * Ant didn't set the proper "magic" value for tar entries containing
   long file names in GNU longfile mode.
   Bugzilla Report 47653.

 * The tar task failed to recognize that the archive had to be
   (re-)created in some cases where the sources are filesystem based
   resources but not filesets.
   Bugzilla Report 48035. 

 * <sshexec>'s outputproperty was prefixed by the executed command
   when the command attribute has been used, breaking backwards
   compatibility to Ant 1.7.0.
   Bugzilla Report 48040.

 * different task instances of the same <scriptdef>ed tasks could
   overwrite each others attributes/nested elements.
   Bugzilla Report 41602.

 * The Hashvalue algortihm implementation of the modified task could
   fail to read the file(s) completely.
   Bugzilla Report 48313.

Other changes:
--------------

 * The get task now also follows redirects from http to https
   Bugzilla Report 47433

 * A HostInfo task was added performing information on hosts, including info on 
   the host ant is running on. 
   Bugzilla Reports 45861 and 31164.

 * There is now a FileProvider interface for resources that act as a source
   of filenames. This should be used by tasks that require resources
   to provide filenames, rather than require that all resources
   are instances or subclasses of FileResource.
   Bugzilla Report 43348
   
 * There is now a URLProvider interface for resources that act as a
   source of URLs. This should be used by tasks that require resources
   to provide URLs, rather than require that all resources are
   instances or subclasses of URLResource.
   
 * Fixcrlf now gives better error messages on bad directory attributes.
   Bugzilla Report 43936
   
 * a new property ant.project.default-target holds the value of the
   current <project>'s default attribute.

 * a new property ant.project.invoked-targets holds a comma separated
   list of the targets that have been specified on the command line
   (the IDE, an <ant> task ...) when invoking the current project.

 * The <type> resource selector has had an "any" type added for better
   configurability.

 * Ant should detect the OS as both a Mac and a Unix system when
   running on OpenJDK.
   Bugzilla Report 44889.

 * new protected getConnection and getStatement methods allow
   subclasses of SQLExec more control - or access to the cached
   instances when overriding other methods like runStatements.
   Bugzilla Report 27178.

 * <sql> has a new failOnConnectionError attribute that can be used to
   keep a build going even if the task failed to connect to the
   database.
   Bugzilla Report 36712.

 * A new attribute strictDelimiterMatching can be used to ignore case
   or whitespace differences when <sql> searches for delimiters.
   This is useful if you execute a SQL script that has contains "GO"
   and "go" as delimiters.
   Bugzilla Report 26459.

 * A new showWarnings attribute of <sql> allows warnings to be logged.
   Bugzilla Report 41836.

 * A new treatWarningsAsErrors attribute of <sql> can be used to fail
   a build if a warning occurs.
   Bugzilla Report 41836.

 * Ant now supports scoped properties (see Local task).
   Bugzilla Report 23942.

 * <sql>'s CSV output can be controlled via the new attributes
   csvColumnSeparator and csvQuoteCharacter.
   Bugzilla Report 35627.

 * <ftp>'s logging has been improved.
   Bugzilla Reports 30932, 31743.

 * It is now possible to disable <ftp>'s remote verification.
   Bugzilla Report 35471.

 * <sshexec> now supports input in a way similar to <exec>
   Bugzilla Report 39197.

 * <scp> can now preserve the file modification time when downloading
   files.
   Bugzilla Report 33939.

 * the new task sshsession can run multiple tasks in the presence of
   an SSH session providing (local and remote) tunnels.
   Bugzilla Report 43083.

 * ZipOutputStream has been sped up for certain usage scenarios that
   are not used by Ant's family of zip tasks.
   Bugzilla Report 45396.

 * <echo> supports an "output" Resource attribute as an alternative to "file".

 * <sql> "output" attribute now supports any Resource in addition to a file.

 * <scp> no longer requires a passphrase when using key based
   authentication.
   Bugzilla Report 33718.

 * a new failOnEmptyArchive attribute on <unzip> and <untar> can now
   make the task fail the build if it tries to extract an empty
   archive.

 * <unzip> and <untar> have a new attribute stripAbsolutePathSpec.
   When set to true, Ant will remove any leading path separator from
   the archived entry's name before extracting it (making the name a
   relative file name).
   Bugzilla Report 28911.

 * <unzip> will now detect that it was asked to extract a file that is
   not an archive earlier if the file is big.
   Bugzilla Report 45463.

 * New file and resource selectors <readable/> and <writable/> have
   been added that select file which the current process can read or
   write.
   Bugzilla Report 45081.

 * The filename file selector has a new attribute regex that allows
   files to be selected by matching their names against a regular
   expression.
   Bugzilla Report 45284

 * The name resource selector has a new attribute regex that allows
   resources to be selected by matching their names against a regular
   expression.
   Bugzilla Report 45284

 * Enhanced performance of Project.fireMessageLoggedEvent and DirectoryScanner 
   Bugzilla Reports 45651 and 45665

 * The package list location for offline links can now be specified as
   an URL.
   Bugzilla Report 28881

 * <echoxml> now supports XML namespaces.
   Bugzilla Report 36804.

 * A new listener for <junit> has been added that tries to invoke the
   tearDown method of a TestCase if that TestCase was run in a forked
   VM and the VM crashed or a timeout occured.  See the <junit> task's
   manual page for details.
   Bugzilla Report 37241.

 * The Jar task now supports the addition of a jar index file in update mode.
   Previously the absence of the index was not enough to trigger the rebuild;
   some other update was necessary.
   Bugzilla report 45098.

 * <ant> has a new attribute "useNativeBasedir" that makes the child
   build use the same basedir it would have used if invoked from the
   command line.  No matter what other attributes/properties have been
   set.
   Bugzilla Report 45711.

 * <patch> has a new optional failOnError attribute.
   Bugzilla Report 44772.

 * Antlib descriptors will now be parsed by the configured
   ProjectHelper if the implementation overrides the new
   canParseAntlibDescriptor and parseAntlibDescriptor methods.  If the
   configured helper doesn't override the methods, a new instance of
   ProjectHelper2 will be used just like in Ant 1.7.1.
   Bugzilla Report 42208.

 * It is now possible to explicitly set the executable used by
   <signjar>.
   Bugzilla Report 39189.

   mapper that matches.
   Bugzilla Report 44873

 * <get> has a new maxtime attribute that terminates downloads that
   are taking too long.
   Bugzilla Report 45181.

 * <ftp> now supports selectors for remote directories as well.
   Bugzilla Report 44726.

 * In some cases Ant fails to rename files if the source or target
   file has just recently been closed on Windows.  It will now try to
   delete the offending file once again after giving the Java VM time
   to really close the file.
   Bugzilla Report 45960.

 * two new properties can be used to set the MIME-Type and charset
   used by MailLogger.
   Bugzilla Report 27211.

   reach at least one given recipient.
   Bugzilla Report 36446.

 * two new properties allow MailLogger to send a fixed text instead of
   the log file.
   Bugzilla Report 38029.

 * <cvsversion> is supposed to support CVSNT now.
   Bugzilla Report 31409.

 * <cvs>' port attribute should now work for all clients that use the
   environment variable CVS_PSERVER_PORT instead of the "official"
   CVS_CLIENT_PORT.
   Bugzilla Report 30124.

 * <cvsversion> now works for local repositories as well.

 * <cvstagdiff> has an option to ignore removed files now.
   Bugzilla Report 26257.

 * <cvs> and friends now support modules with spaces in their names
   via nested <module> elements.

 * A new attribute "ignoreEmpty" controls how <concat> deals when
   there are no resources to concatenate.  If it is set to false, the
   destination file will be created regardless, which reinstates the
   behavior of Ant 1.7.0.
   Bugzilla Report 46010.

 * If the new remote attribute is set to true, <cvschangelog> can now
   work against a remote repository without any working copy.
   Bugzilla Report 27419.

 * start and end tags can now be used instead of dates in
   <cvschangelog>.
   Bugzilla Report 27419.

 * MailLogger and <mail> can now optionally enable support for
   STARTTLS.
   Bugzilla Report 46063.

 * <import> has new attributes "as" and "prefixSeparator" that can be
   used to control the prefix prepended to the imported targets'
   names.

 * a new task <include> provides an alternative to <import> that
   should be preferred when you don't want to override any targets.

 * delete has a new attribute removeNotFollowedSymlink.  If set to
   true, symbolic links not followed (because followSymlinks was false
   or the number of symlinks was too big) will be removed.
   Bugzilla Report 36658.

 * the os and osfamily attributes of <chown>, <chgrp>, <chmod> and
   <attrib> can now be used to run the commands on operating systems
   other than their "native" environment, i.e. non-Unix or non-Windows
   operating systems respectively.

   and fullpath attributes of <zipfileset> to arbitrary mappers that
   can be applied to arbitrary resource collections.
   Bugzilla Report 4240.

 * <tarfileset> and <zipfileset> have a new attribute
   errorOnMissingArchive that allows "optional" filesets that don't
   break the build if the archive doesn't exist.
   Bugzilla Report 46091.

 * <javadoc> has new attributes that correspond to the
   -docfilessubdirs and -excludedocfilessubdir command line arguments.
   Bugzilla Report 34455.

 * <xslt> now fails early if a specified stylesheet doesn't exist.
   Bugzilla Report 34525.

 * <xslt> now has an option to supress transformer warnings.  This
   option only has an effect for processors that support this feature;
   the "trax" processor included with Ant does support it.
   Bugzilla Report 18897.

 * <xslt> has two new attributes failOnError and
   failOnTransformationError that can be used to not make the build
   process proceed if an error occurs.
   Bugzilla Report 36260.

 * <xslt> has a new attribute failOnNoResources that can be used to 
   make the build fail/continue if the collection of resources to
   transform is empty.
   Bugzilla Report 46274.

 * It is now possible to define system properties that should be set
   during xslt's transformation.  This can be used to enable XInclude
   processing in Xerces, for example.
   Bugzilla Report 36653.

 * a new resource collection <archives> can be used to specify
   collections of ZIP and TAR archives as sources.  It extracts them on
   the fly.  This is a generalization of the <zipgroupfileset> found
   as nested element of <zip> and friends.
   Bugzilla Report 46257.

 * <dependset> has a new verbose attribute that makes the task list
   all deleted targets and give a hint as to why it deleted them.
   Bugzilla Report 13681.

 * <replaceregexp> now supports arbitrary filesystem based resource
   collections.
   Bugzilla Report 46341.

 * <replace> now supports arbitrary filesystem based resource
   collections.

 * token and value of <replace>'s nested <replacefilter> can now also
   be specified as nested elements to allow multiline content more
   easily.
   Bugzilla Report 39568.

 * <replace> and <replaceregexp> can now optionally preserve the file
   timestamp even if the file is modified.
   Bugzilla Report 39002.

 * The <replace> child-elements <replacetoken> and <replacevalue> have
   a new attribute that controls whether properties in nested text get
   expanded.
   Bugzilla Report 11585.

 * <replace> has a new attribute failOnNoReplacements that makes the
   build fail if the task didn't do anything.
   Bugzilla Report 21064.

 * <sync>'s <preserveInTarget> has a new attribute that controls
   whether empty directories should be kept.
   Bugzilla Report 43159.

 * ant -diagnostics now checks that it can read as much from the
   temporary directory as it has written.  This may help detecting a
   full filesystem.
   Bugzilla Report 32676.

 * <pathconvert> has a new preserveduplicates attribute--historically
   these were eliminated in the interest of behaving in the manner
   of a "path."

 * <javac>'s source and target attributes are no longer ignored when
   using gcj.
   Bugzilla Issue 46617.

 * ant -diagnostics now outputs information about the default XSLT
   processor.
   Bugzilla Issue 46612.

   a size.
   Bugzilla Report 42940.

 * CBZip2OutputStream now has a finish method separate from close.
   Bugzilla Report 42713.

 * the <zip> and <unzip> family of tasks has new options to deal with
   file name and comment encoding.  Please see the zip tasks'
   documentation for details.

 * <input ...><handler type="secure" /></input> now uses previously
   undocumented SecureInputHandler shipped with Ant 1.7.1.

 * Command line arguments for <exec> and similar tasks can now have
   optional prefix and suffix attributes.

 * <rmic>'s new executable attribute can be used to specify a
   different executable.
   Bugzilla Report 42132.

 * <javac>, <rmic>, <javah> and <native2ascii> now provide a nested
   element to specify a classpath that will be used when loading the
   task's (compiler) adapter class.
   Bugzilla Report 11143.

 * <javac>, <rmic>, <javah> and <native2ascii> now provide a nested
   element to specify the task's (compiler) adapter as an instance of
   a class that has been defined via typedef/componentdef.  This
   allows more control over the classpath and allows adapters to be
   defined in Antlibs easily.

 * A new subclass org.apache.tools.ant.loader.AntClassLoader5 of
   AntClassLoader has been added which overrides getResources
   which became non-final in ClassLoader with Java5+ so
   this method now behaves as expected.
   The new subclass will be used by Ant internally if it is available
   and Ant is running on Java5 or more recent.
   Bugzilla Report 46752.

 * a new attributes can chose a different request method than GET for
   the http condition.

   Bugzilla Report 20699.

 * <rmic> has a new listfiles attribute similar to the existing one of
   <javac>.

 * <sql> has two new attributes errorproperty and warningproperty that
   can be set if an error/warning occurs.
   Bugzilla Report 38807.

 * <sql> has a new attribute rowcountproperty that can be used to set
   a property to the number of rows affected by a task execution.
   Bugzilla Report 40923.

 * when Ant copies files without filtering, it will now use NIO
   channels.
   Bugzilla Report 30094.

 * <get> has a new attribute that can be used to disable caching on
   HTTP connections at the HttpUrlConnection level.
   Bugzilla Report 41891.

 * <tar> and <zip> (and tasks derived from <zip>) will now create the
   parent directory of the destination archive if it doesn't exist.

   attribute different from the <classfileset>.
   Bugzilla Report 37763.

 * <path> can now optionally cache its contents.

 * <property> can now specify values as nested text.
   Bugzilla Report 32917.

 * a new parentFirst attribute on <javaresource> allows resources to
   be loaded from the specified classpath rather than the system
   classloader.
   Bugzilla Report 41369.
   
 * <property location="from" basedir="to" relative="true"/> can now
   calculate relative paths.

 * The <name> selector supports a new handleDirSep attribute that
   makes it ignore differences between / and \ separators.
   Bugzilla Report 47858.

 * <get> now supports resource collections (as long as the resources
   contained provide URLs) and can get multiple resources in a single
   task.

 * <import> can now import non-File resources if they provide an URL
   - as the <url> and <javaresource> resources do.
   Bugzilla Report 29251
   
 * <import> can now import multiple resources specified as resource
   collections.
   Bugzilla Report 22269.

 * a new <resourcelist> type is similar to <filelist> but can read the
   list of resources from non-file resources and may return resources
   that are not files.

 * a new filterreader appendtolines complements prefixlines.

 * a new top level element extension-point allows build files to be
   extended with custom targets more easily.

Changes from Ant 1.7.0 TO Ant 1.7.1
=============================================

Changes that could break older environments:
-------------------------------------------

* String resources only have properties single expanded. If you relied on
  <string> resources being expanded more than once, it no longer happens.
  Bugzilla report 42277.

* A String resource's encoding attribute was only taken into account when
  set from the resource's OutputStream; the InputStream provided the String's
  binary content according to the platform's default encoding. Behavior has
  been modified to encode outgoing (InputStream) content as well as encoding
  incoming (OutputStream) content.

* <java> with fork now returns gives -1 instead of 0 as result when failonerror
  is false and some exception (including timeout) occurs. Br 42377. 

* ant-type attribute has been marked as deprecated and a warning has been
  issued if it is encountered in the build file.

* Rolling back Bugzilla 32927 (set a default description for a javadoc tag
  if not set) as it caused a BC problem.
  Bugzilla report 41268.

* <apt> forks properly and so memory settings are picked up.
  Bug report 41280.

* Handle null result of system getProperty(). Bugzilla 42334.

* Regression: concat fixlastline="true" should not have applied to
  nested text, but did in Ant 1.7.0. Bugzilla 42369.

* Regression: ant.version was not passed down in <ant>, <subant>.
  This worked in Ant 1.6.5, but not in 1.7.0.
  ant.core.lib (added in 1.7.0) was also not being propagated.

  resourceCollection contexts in Ant 1.7.0. Bugzilla 42967.

* <property> supports loading from xml based property definition.
  Bugzilla 42946

* <junit> supports collecting and rerunning failed test cases
  (textXXX methods). Bugzilla 42984.

  Apache Cactus' Ant task).  The changes have been modified so that
  subclases should now work again - without any changes to the
  subclass.

Other changes:
--------------

  filesets, reducing both I/O and CPU usage.

* Profiling logger has been added with basic profiling capabilities.

* <script> now has basic support for JavaFX scripts

* SSH task can now take a command parameter containing the commands to execute.
  This allows you to connect to a server and execute a number of commands
  without constantly reconnecting for each command.

* Upgraded XML API to XML commons version 1.3.04.

* Upgraded to Xerces 2.9.0

* <script> can now work with bsf.jar and js.jar in its <classpath>.

  Bugzilla 29154

* Show Previous Revision in the tagdiff.xsl stylesheet
  Bugzilla 29143

* Allow <mapper refid> to refer directly to a FileNameMapper instance.

* If you try and use a type in a namespace (or an antlib), and the type is not
  recognized but there are other definitions in that namespace, Ant lists what
  the known definitions are. This helps you find spelling errors.

* Add a <last> resource collection, corresponding to <first>.

* Add new <truncate> task.

* <junitreport> xsl stylesheets allow setting the title used in <title> and <h1> tags by
  using <report><param> element.  Bugzilla 41742.

  define scripts in JARs, remote URLs, or any other supported resource. Bugzilla report 41597.

* <concat> is now usable as a single-element ResourceCollection.

* It is now possible to provide the value of a <striplinecomments> filter's
  <comment> nested element as nested text instead of using the 'value'
  attribute.

* A new logger, BigProjectLogger, lists the project name with every target   

* Default text added to macrodef. Bugzilla report 42301.

* "rawblobs" attribute added to SQL task.

  Bugzilla 43114.

* SecureInputHandler added to use Java 6 System.console().readPassword()
  when available.

Changes from Ant 1.6.5 to Ant 1.7.0
===================================

Changes that could break older environments:
-------------------------------------------

* Initial support for JDK 6 (JSR 223) scripting.
  <*script*> tasks will now use javax.scripting if BSF is
  not available, or if explicitly requested by using
  a "manager" attribute.

* Removed launcher classes from nodeps jar.

* <classconstants> filter reader uses ISO-8859-1 encoding to read
  the java class file. Bugzilla report 33604.

* Defer reference process. Bugzilla 36955, 34458, 37688.
  This may break build files in which a reference was set in a target which was
  never executed. Historically, Ant would set the reference early on, during parse
  time, so the datatype would be defined. Now it requires the reference to have
  been in a bit of the build file which was actually executed. If you get
  an error about an undefined reference, locate the reference and move it somewhere
  where it is used, or fix the depends attribute of the target in question to
  depend on the target which defines the reference/datatype.
  As a result of testing on real live build scripts, a fall-back mechanism
  was put it place to allow references that are out-of-band to be resolved. If
  this happens a big warning message is logged. This fall-back mechanism will
  be removed in Ant 1.8.0.

* <script> and <scriptdef> now set the current thread context.

* Unrestrict the dbvendor names in the websphere element of the ejbjar task.
  Bugzilla Report 40475.

* <env> nested element in <java>, <exec> and others is now case-insensitive
  for windows OS. Bugzilla Report 28874.

* Removed support for xalan1 completely. Users of Xalan1 for Ant builds will
  have to stay at ant 1.6.5 or upgrade to xalan2.

* Use org.apache.log4j.Logger instead of org.apache.log4j.Category.
  Category has been deprecated for ~2 years and has been removed from
  the log4j code.  Logger was introduced in log4j 1.2 so users of
  log4j 1.1 and log4j 1.0 need to upgrade to a newer version of log4j.
  Bugzilla Report 31951.

* build.sysclasspath now also affects the bootclasspath handling of
  spawned Java VMs.  If you set build.sysclasspath to anything other
  than "ignore" (or leave it unset, since "ignore" is the default when
  it comes to bootclasspath handling), then the bootclasspath of the
  VM running Ant will be added to the bootclasspath you've specified.

* The <java fork="false"> now as per default installs a security manager
  using the default permissions. This is now independent of the
  failonerror attribute.  Bugzilla report 33361.

* <signjar> now notices when the jar and signedjar are equal, and switches
  to the same dependency logic as when signedjar is omitted. This may break
  something that depended upon signing in this situation. However, since
  invoking the JDK jarsigner program with -signedjar set to the source jar
  actually crashes the JVM on our (Java1.5) systems, we don't think any
  build files which actually worked will be affected by the change.

* <signjar> used to ignore a nested fileset when a jar was also provided as an
  attribute, printing a warning message; now it signs files in the fileset.

* An improved method of handling timestamp granularity differences between
  client and server was added to the <ftp> task.  FTP servers typically
  have HH:mm timestamps whereas local filesystems have HH:mm:ss timestamps.
  Previously, this required tweaking with the timediffmillis attribute
  which also was used to handle timezone differences.  Now, there is a new
  timestampgranularity attribute.  The default value for get operations is 0
  since the user has the more powerful preservelastmodified attribute to work
  with.  Since this is not available on put operations the default value
  adds a minute to the server timestamp in order to account for this,
  Scripts which previously used timediffmillis to do this compensation may
  need to be rewritten.  timediffmillis has now been deprecated.

* Support for the XSL:P XML parser has been removed.
  Bugzilla Report 23455.

* Visual Age for Java optional tasks removed as the required library is no
  longer available.

* Testlet (test) optional task removed as the required library is no
  longer available.

* IContract optional task removed as the required library is no
  longer available.

* Metamata (maudit, mmetrics, and mparse tasks) removed as the required 
  library is no longer available.

* Sitraka (jpcoverage, jpcovmerge, jpcovreport) tasks suppressed as the 
  required library is no longer available.

* <fixcrlf> used \r (Mac) line endings on OS X, whose proper line separator
  is \n (Unix).  Bugzilla report 39585.

* <scp> now optionally supports the sftp protocol, you may need a
  newer jsch.jar.  Bugzilla Report 39373.

* Ant launcher program prints errors to stderr, and exits with a 2 exit code
  value if, for any reason, it cannot actually start Ant proper. This will only
  affect programs/scripts that called the launcher and which did not want to
  receive an error if Ant itself would not start

* All .NET tasks are now deprecated in favor of the new .NET Antlib:
  http://ant.apache.org/antlibs/dotnet/index.html

Fixed bugs:
-----------
* Directory deletion did not work properly.
  Bugzilla 40972.

* docletpath attribute of javadoc was ignored.
  Bugzilla 40900.

* Fixed incorrect recursion in DOMUtil.listChildNodes().
  Bugzilla 40918.

* CompressedResource.compareTo() did not
  take comparison with another CompressedResource into account.
  Bugzilla 40949.

* Avoid possible NPE in Jar.java.
  Bugzilla 40847.

* regression in attribute prefix (+ others) for refid in zipfileset and tarfileset.
  Bugzilla 41004, 30498.

* dependset failed if the basedir of a target fileset did not exist.
  Bugzilla 40916.

* Recursive filtering encountered NullPointerExceptions under certain
  circumstances.  Bugzilla 41086.

* XmlProperty overrides previously set property value when handling duplicate
  elements. Bugzilla 41080.

* Having many tasks causes OOM.  Bugzilla 41049.

* Regression: <path> was evaluating nested content only once, so that it could

* The inheritance hierarchy of the legacy <path> type was changed; code built
  against Ant 1.7 would therefore no longer execute on older versions of Ant.

  erroneously deleted the "destination" file before attempting to rename
  the source file.  Bugzilla 37701.

* <scp> can now handle uris with @s other than the final one denoting the
  domain.  Bugzilla 38082.

* If the class invoked by the <java> task threw a ClassNotFoundException,
  this was misinterpreted as the specified class itself not being found.

* <echoproperties> setPrefix javadoc claimed null or empty prefix would be
  ignored; instead an error was thrown.  Bugzilla report 39954.

* <xslt> passes the current file (name + directory) to the
  stylesheet/transformation.  xsl-parameter name is configurable.
  Bugzilla report 21042.

  habitual offender was the subclassed <jar>, which included META-INF/ in
  the destination file regardless of whether filesonly was set to true.

* Roll back automatic proxy enabling on Java 1.5. It broke things like
  Oracle JDBC drivers, and Ant itself on IBM's JVM on AIX, and didnt
  seem to work to well the rest of the time.
  To enable the feature, use the -autoproxy command line option.

* Upgraded XML API and parser to Xerces 2.8.1

* A code review of some threaded logic has tightened up the synchronization
  of Watchdog, ExecuteWatchdog and ExecuteJava, which could reduce the occurence
  of race conditions here, especially on Java1.5+.

* Allow broken reference build files. The defer reference processing would
  break too many files - so allow them with a warning.

* Removed dependency on sun.misc.UUEncoder for UUMailer.

* Added regex attribute to the echoproperties task.
  Bugzilla 40019.

* <war> task now allows you to omit the web.xml file. as this is optional
  in the servlet 2.5 and Java EE 5 APIs. set needxmlfile="false" to
  avoid a missing web.xml file from halting the build.

* Diagnostics catches and logs security exceptions when accessing system properties.

* <javadoc> useexternalfile now applies to all command line arguments
  of javadoc. Bugzilla report 40852.

* Added classpath attribute and nested element to <script> to allow
  the language jars to be specified in the build script.
  Bugzilla report 29676.

* Trim the driver attribute on the <sql> task. Bugzilla report 21228.

  used (if set) in preference to the passed in project, when
  dereferencing the reference. Bugzilla Report 25777.

* On DOS and Netware, filenames beginning with a drive letter
  and followed by a colon but with no directory separator following
  the colon are no longer (incorrectly) accepted as absolute pathnames
  by FileUtils.normalize() and FileUtils.isAbsolutePath().  Netware
  volumes can still be specified without an intervening separator.
  UNC pathnames on Windows must include a server and share name, i.e.
  "\\a\b" to be considered valid absolute paths.

* A bug in SQLExec would prevent the execution of trailing,
  non-semicolon-delimited statements.  Bugzilla Report 37764.

  before echoing. Bugzilla report 18976.

* A new base class DispatchTask has been added to facilitate elegant
  creation of tasks with multiple actions.

* Major revision of <wsdltodotnet>. Supports mono wsdl and the microsoft
  wsdl run on mono, as well as most of the .NET WSE2.0 options. Extra
  schemas (files or urls) can be named in the <schema> element.
  Compilers can be selected using the compiler attribute, which defaults
  to "microsoft" on windows, and "mono" on everything else.

* It is now possible to specify the pattern created/parsed by <checksum>.
  Bugzilla Report 16539.

* Added a new "failall" value for the onerror attribute of <typedef>.

  for XML Schema (XSD) files.

* <fixcrlf> supports a file attribute for easy fixup of a single file.

* New condition <parsersupports> which can look for XML parser feature or
  property support in the parser Ant is using.

* fixcrlf can be used in a filterchain.

* <sync> has a new nested element <preserveInTarget> that can be used
  to protect extra-content in the target directory.  Bugzilla Report
  21832.

* <signjar> now supports:
  -nested filesets at the same time as the jar attribute
  -a destDir attribute with the appropriate dependency logic, which
   can be used with the jar attribute or nested filesets
  -a mapper to permit filename remapping on signing
  -tsaurl and tsacert attributes for timestamped JAR signing
  -nested <sysproperty> elements, which can be used for proxy setup
  and the like

* The linecontains and linecontainsregexp filterreaders now support a
  negate attribute to select lines -not- containing specified text.
  Bugzilla Report 34374.

* <os> condition adds "winnt" as a family which can be tested. This is
  all windows platforms other than the Win9x line or Windows CE.

* <exec> (and hence, <apply> and any other derived classes) have an OsFamily
  attribute, which can restrict execution to a single OS family.

* Added "backtrace" attribute to macrodef. Bugzilla report 27219.

* Ant main provides some diagnostics if it ever sees a -cp or -lib option,
  as this is indicative of a script mismatch. Bugzilla report 34860

* <junitreport> prints a special message if supplied an empty XML File. This
  can be caused by the test JVM exiting during a test, either via a
  System.exit() call or a JVM crash.

* Project name is now used for *all* targets so one can write consistent import
  build files. Bugzilla report 28444.

* New condition <typefound> that can be used to probe for the declaration
  and implementation of a task, type, preset, macro, scriptdef, whatever.
  As it tests for the implementation, it can be used to check for optional
  tasks being available.

* Check for 1.5.* Ant main class. (weblogic.jar in classpath reports)

* New condition <isfailure> that tests the return-code of an executable. This
  contains platform-specific logic and is better than comparing the result with
  "0".

* Added initial support for Resource Collections, including the
  resourcecount task.

* property attribute of pathconvert is now optional. If omitted the
  result will be written to the log.

* New mapper, <scriptmapper>, supports scripted mapping of source files/strings

  url; and nested filesets/paths into a (space, comma, whatever) separated
  list of URLs. Useful for RMI classpath setup, amongst other things.

* <xslt> now accepts nested FileNameMappers e.g. <globmapper>.
  Bugzilla report 37604.

* New task <loadresource> that accompanies <loadfile> for non file resources.

* <echo> now supports an encoding when saving to a file.

* Add textfile attribute to the <filesmatch> condition. When true, the text
  contents of the two files are compared, ignoring line ending differences.

* New <resourcesmatch> condition.

* Added the onmissingfiltersfile attribute to filterset. Bugzilla report 19845.

* Added the inline handler element to the input task.

* <sql> supports property expansion if you set the expandProperties
  attribute. By default it does not expand properties, something we
  dare not change for fear of breaking complex SQL operations in
  existing files.

* <javadoc>'s packagenames attribute is now optional and defaults to "*".

* <javac>'s source and target attributes as well as <javadoc>'s source
  attribute will read default values from the properties
  ant.build.javac.source and ant.build.javac.target.

  especially under an IDE. Don't rely on this being called.

* <scriptdef>-created scripts have support for nested text. All text
  passed to a scripted task can be accessed via self.text.

* <fixcrlf> now supports an outputencoding attribute.  Bugzilla report 39697.

* <junitreport> now supports nested XSL parameters. Bugzilla report 39708.

  class. This class must implement the interface AntMain

Changes from Ant 1.6.4 to Ant 1.6.5
===================================

Changes that could break older environments:
--------------------------------------------

Fixed bugs:
-----------

* <move> was unable to replace existing files or write into
  existing directories.  Bugzilla report 34962.

* <macrodef> with redefined default values was incorrect. (Fix for
   31215 had a bug). Bugzilla report 35109.

* <javadoc> will convert backslashes to forwardslashes when generating file
  list by useexternalfile. Bugzilla report 27814.

Changes from Ant 1.6.3 to Ant 1.6.4
===================================

Changes that could break older environments:
--------------------------------------------
* <ftp> task has had a number of changes.  Uptodate calculation previously
  did not call a file uptodate if the source timestamp and the destination
  timestamp were equal. Bugzilla report 34941.  Any script that attempted
  to compensate for this by using the timediffmillis attribute might need
  to be tweaked.


Fixed bugs:
-----------

* Sun javah failed with java.lang.NoClassDefFoundError.
  Bugzilla report 34681.

* DirectoryScanner.slowScan() was broken. Bugzilla report 34722.

* DirectoryScanner.scan() could throw a NullPointerException on
  case-insensitive filesystems (read Windows or MacOS X).

* Get w/authentication failed with ArrayOutOfBoundsExceptions.
  Bugzilla report 34734.

* Granularity attribute for <sync> task was undocumented.
  Bugzilla report 34871.

* <unzip> and <untar> could leave file handles open on invalid
  archives.  Bugzilla report 34893.

* propertyset threw NPE with nested, mapped propertysets.

Other changes:
--------------

* AntXMLContext.setCurrentTargets() is now public. Bugzilla report 34680.

Changes from Ant 1.6.2 to Ant 1.6.3
===================================

Changes that could break older environments:
--------------------------------------------

* The subant task used the canonical version of a file path. This
  has been changed to use the absolute path. Bugzilla 30438.

* Tar now writes two EOF blocks rather than one.
  Bugzilla report 28776

* The Reference object now has a project field which it uses in preference
  to the project passed in. This allows composite references to be
  handled to nested projects.
  Bugzilla report 25777

* <junit> with filtertrace="true" will now also swallow lines for the
  sun.reflect package.  If you need to see them in your stack trace,
  you must set filtertrace to false.
  Bugzilla Report 22758

* The jikes compiler adapter now supports -bootclasspath, -extdirs and
  -sourcepath and also uses the same logic for debug flags as javac.
  This means, the jikes compiler adapter now requires Jikes 1.15 or later.
  Bugzilla Reports 25868, 26404 and 32609.

* The gcj compiler adapter used to include the Java runtime classes
  even if includeJavaRuntime was set to false, unless the
  bootclasspath has been specified as well.  It will now always adhere
  to includeJavaRuntime, you may need to set it to true explicitly now
  if you relied on the old behavior.

Other changes:

* When a BuildListener tried to access System.err or System.out, Ant
  would have thrown an exception - this has been changed.  Ant now
  silently ignores the message.  BuildListeners still should avoid
  accessing either stream.

* Added a comment attribute to the zip task.
  Bugzilla report 22793.

* Overloaded FileUtils.createNewFile with a boolean mkdirs attribute
  to create nonexistent parent directories.

* <apply> has a new "force" attribute that, when true, disables
  checking of target files.

* Made the dest attribute of the apply task optional; mapped target
  filenames will be interpreted as absolute pathnames when dest is omitted.

* Changed default tempdir for <javac> from user.dir to java.io.tmpdir.

* Added searchpath attribute to <exec> for searching path variable(s)
  when resolveexecutable = true.

* Added revision and userid attributes to <pvcs> documentation.

* Added support to the touch task for a mkdirs attribute to create
  nonexistent parent directories before touching new files.

* Added support to the touch task for a pattern attribute to allow
  alternate datetime formats.

* Added support to the touch task to map touched files using a nested
  mapper element.

* Added support to the touch task for a verbose attribute to suppress
  logging of new file creation.

* bad link in docs to the enhancement page in bugzilla.
  Bugzilla report 33252.

* Added length task to get strings' and files' lengths.

* <native2ascii> and <javah> now also support Kaffe's versions.

* Recursive token expansion in a filterset can now be disabled by
  setting its recurse attribute to false.

* Pathconvert no longer requires that one of (targetos|pathsep|dirsep)
  be set; platform defaults are used when this is the case.

* Added preservelastmodified attribute to fixcrlf task. Bugzilla 25770.

* Added isfileselected condition.

* Added verbose="true|false" attribute to <subant>. When verbose is enabled,
  the directory name is logged on entry and exit of the sub-build.
  Bugzilla 33787.

* Added -nouserlib option to allow running ant without automatically loading
  up ${user.home}/.lib/ant. This is useful when compiling ant, and antlibs.
  Modified the build.sh and build.bat to use the option.

* Added -noclasspath option to allow running ant WITHOUT using CLASSPATH env
  variable. Modified ant.bat to do this so that %CLASSPATH% is not looked at.

* Add else attribute to the condition task, which specifies an
  optional alternate value to set the property to if the nested
  condition evaluates to false. Bugzilla report 33074.

* Ant generated jar files should now be detected as jar files by
  Solaris.  Bugzilla Report 32649.

* <rexec> with a single command should now work with unusal login
  dialogs without special read/write pairs.  Bugzilla Report 26632.

* <csc>'s extraoptions can now contain multiple arguments.
  Bugzilla Report 23599.

* <macrodef> with default values set by properties would be
  seen as new definitions when called twice with different properties.
  This was confusing so the definitions are now treated as similar.
  Bugzilla Report 31215.

* <javadoc> has a new attribute "includenosourcepackages" that can be
  used to document packages that don't hold source files but a
  package.html file.  Bugzilla Report 25339.

* <rpm> has new attributes failonerror and quiet.

* Added two tutorials
  - beginner: introduction into Ant
  - task developers: using path, fileset etc

* a number of new attributes that allow the user to handle non-standard
  server listing formats and time zone differences have been added in
  the <ftp> task.


Fixed bugs:
-----------

  passed in with the current basedir leading twice:
  e.g. ${basedir}${file.separator}${basedir}${file.separator}foo .

* The first file open that took place when using input files with the
  <exec>, <apply>, or <java> tasks was always logged to System.out

  Bugzilla Report 33618.

* <zip> would drop files matched by defaultexcludes during updates.

* The refid attribute of the I/O redirector was not functional.

Changes from Ant 1.6.1 to Ant 1.6.2
===================================

Changes that could break older environments:
--------------------------------------------

* The import task used the canonical version of a file path. This
  has been changed to use the absolute path. Bugzilla 28505.

* ant-xalan2.jar has been removed since the only class contained in it
  didn't depend on Xalan-J 2 at all.  Its sole dependency has always
  been TraX and so it has been merged into ant-trax.jar.

* All exceptions thrown by tasks are now wrapped in a buildexception
  giving the location in the buildfile of the task.

* Nested elements for namespaced tasks and types may belong to the
  Ant default namespace as well as the task's or type's namespace.

* <junitreport> will very likely no longer work with Xalan-J 1.

  Note that Xalan-J 1 has been deprecated for a very long time and we
  highly recommend that you upgrade.

  If you really need to continue using Xalan-J 1, please copy the
  junit-frames-xalan1.xsl from the distribution's etc directory as
  junit-frames.xsl into a new directory and use the task's styledir
  attribute to point to.  This is the last version of the XSLT
  stylesheet that is expected to be compatible with Xalan-J 1.

Fixed bugs:
-----------

* eliminate memory leak in AntClassLoader. Bugzilla Report 8689.

* subant haltonfailure=false did not catch all failures. Bugzilla Report 27007.

* MacroDef did not allow attributes named 'description'. Bugzilla Report 27175.

* Throw build exception if name attribute missing from patternset#NameEntry.
  Bugzilla Report 25982.

* Throw build exception if target repeated in build file, but allow targets
  to be repeated in imported files.

* <apply> didn't compare timestamps of source and targetfiles when
  using a nested <filelist>.  Bugzilla Report 26985.

* tagdiff.xml was broken in ant 1.6.1. Bugzilla Report 27057.

* if the basedir contained .. or . dirs, and the build file name contained
  .. or ., the basedir was set incorrectly. Bugzilla Report 26765.

* regression from ant 1.5, exec task outputted two redundant trailing newlines.
  Bugzilla Report 27546.

  Bugzilla report 27732.

* filterset used by filtertask doesn't respect loglevel. Bugzilla Report 27568.

* wrong compare used in ProjectComponent for logging. Bugzilla Report 28070.

* failOnAny attribute for <parallel> was broken. Bugzilla Report 28122.

* If <javac> uses gcj and any of the nested <compilerarg>s implies
  compilation to native code (like -o or --main), Ant will not pass
  the -C switch to gcj.  This means you can now compile to native code
  with gcj which has been impossible in Ant < 1.6.2.

* <import optional="false"> and <import optional="true">
  behaved identically.

* <xslt> now sets the context classloader if you've specified a nested
  <classpath>.  Bugzilla Report 24802.

* <zip> and friends would delete the original file when trying to update
  a read-only archive.  Bugzilla Report 28419.

* <junit> and <assertions> are working together. Bugzilla report 27218

* AntClassLoader#getResource could return invalid URLs.  Bugzilla
  Report 28060.

* Ant failed to locate tools.jar if the jre directory name wasn't all
  lowercase.  Bugzilla Report 25798.

* Redirector exhibited inconsistent behavior with regard to split
  output.  When sent to file only, files would be created in all
  cases; when split file-property, files were only created if
  writes were performed.

* fixed case handling of scriptdef attributes and elements.

* UNC pathnames did not work for ANT_HOME or -lib locations on Windows.
  Bugzilla report 27922.

* replacestring tokenfilter only replaced the first occurrence.

* AntLikeTasksAtTopLevelTest failed on cygwin.

* <zip whenempty="skip"> didn't work in a common situation.  Bugzilla
  Report 22865.

* <scp> now properly handles remote files and directories with spaces
  in their names.  Bugzilla Report 26097.

* <scp> now has (local|remote)tofile attributes to rename files on the
  fly.  Bugzilla Report 26758.

* <telnet> and <rexec> didn't close the session.  Bugzilla Report 25935.

* <subant> and XmlLogger didn't play nicley together.

Other changes:
--------------

* Docs fixes for xmlvalidate.html, javadoc.html, starteam.
  Bugzilla Reports 27092, 27284, 27554.

* <pathconvert> now accepts nested <mapper>s.  Bugzilla Report 26364.

* Shipped XML parser is now Xerces-J 2.6.2.

  todir that explicitly state the direction of the transfer.

* The OS/2 wrapper scripts have been adapted to use the new launcher.
  Bugzilla Report 28226.

* <sshexec> now also captures stderr output.  Bugzilla Report 28349.

* <xslt> now supports a nested <mapper>.  Bugzilla Report 11249.

* <touch> has filelist support.

* New attribute "negate" on <propertyset> to invert selection criteria.

* Target now supports a Location member.  Bugzilla Report 28599.

* New "pattern" attribute for <date> selector.

* <junit> has a new forkmode attribute that controls the number of
  Java VMs that get created when forking tests.  This allows you to
  run all tests in a single forked JVM reducing the overhead of VM
  creation a lot.  Bugzilla Report 24697.

* <jar> can now optionally create an index for jars different than the
  one it currently builds as well.  See the new <indexjars> element
  for details.  Bugzilla Report 14255.

* Permit building under JDK 1.5. Bugzilla Report 28996.

* minor Javadoc changes. Bugzilla Report 28998.

* Ignore built distributions. Bugzilla Report 28997.

* A new roundup attribute on <zip> and related task can be used to
  control whether the file modification times inside the archive will
  be rounded up or down (since zips only store modification times with
  a granularity of two seconds).  The default remains to round up.
  Bugzilla Report 17934.

* A binary option has been added to <concat>. Bugzilla Report 26312.

* Added DynamicConfiguratorNS, an namespace aware version of
  DynamicConfigurator. Bugzilla Report 28436.

  comparable to those of <condition>, <filter>, and <selector>.

* New <redirector> type introduced to provide extreme I/O flexibility.
  Initial support for <exec>, <apply>, and <java> tasks.

* <apply> has a new ignoremissing attribute (default true for BC)
  which will allow nonexistent files specified via <filelist>s to
  be passed to the executable.  Bugzilla Report 29585.

* <junitreport> now also works with Xalan XSLTC and/or JDK 1.5.
  Bugzilla Report 27541.

* <jspc> doesn't work properly with Tomcat 5.x.  We've implemented a
  work-around but don't intend to support future changes in Tomcat
  5.x.  Please use the jspc task that ships with Tomcat instead of
  Ant's.

Changes from Ant 1.6.0 to Ant 1.6.1
=============================================

Changes that could break older environments:
--------------------------------------------

* License is now Apache License 2.0
  see http://www.apache.org/licenses/ for more information

Fixed bugs:
-----------
* Remove a recursive template call in the junit xsls that could trigger a stack
  overflow. It now uses Xalan extensions to call a Java class directly.
  Bugzilla Report 19301

* Fix spurious infinite loop detection for filters (introduced in ant 1.6.0).
  Bugzilla Report 23154.

* Fix handling of default ant namespace for nested elements.

* Fix jboss element of ejb task (introduced in ant 1.6.0).

* <whichresource> failed to load classes correctly.

* Ant could fail to start with a NullPointerException if
  ANT_HOME/lib/ant-launcher.jar was part of the system CLASSPATH.

* presetdef'ed types did not work with the ant-type attribute

* fixed case handling of macrodef attributes and elements. Bugzilla
  Reports 25687 and 26225.

* <java> ignored the append attribute, Bugzilla Report 26137.

* The gcj compiler adapter for <javac> failed if the destination
  directory didn't exist.  Bugzilla Report 25856.

* Ant now fails with a more useful message if a new process will be
  forked in a directory and that directory doesn't exist.

* <splash> used to break the build on non-GUI environments.  Bugzilla
  report 11482.

  Bugzilla Report 26642.

Other changes:
--------------
* Shipped XML parser is now Xerces-J 2.6.1

* Translate task logs a debug message specifying the number of files
  that it processed.  Bugzilla Report 13938.

* <fixcrlf> has a new attribute - fixlast. Bugzilla Report 23262.

* <p4submit> has 2 new attributes, needsresolveproperty and changeproperty.
  Bugzilla Report 25711.

* add description attributes to macrodef attributes and elements.
  Bugzilla Report 24711.

* Extending ClearCase Tasks :
 - Added an extra option to 'failonerr' to each ClearCase task/command.
 - Extended the functionality of cccheckout. It can check (notco) to see if
  the desired element is already checked out to the current view. Thus it
   won't attempt to check it out again.
 - Added three new ClearCase commands: ccmkattr, ccmkdir, ccmkelem
  Bugzilla Report 26253.

* added nested text support to <macrodef>

* added initial support for Java 1.5.  Java 1.5 is now correctly
  detected by Ant and treated just like Java 1.4.  You can now specify
  source="1.5" in the <javac> task.

* created new task <cvsversion>

* added support for branch logging via the tag attribute in <cvschangelog>
  Bugzilla Report 13510.

* added support the groovy language in the script and scriptdef tasks

Changes from Ant 1.5.4 to Ant 1.6.0
===================================

Changes that could break older environments:
--------------------------------------------

* This version of Ant can not be built with JDK 1.1 and requires at
  least Java 1.2 at runtime as well.  Compiling for a 1.1 target is
  still supported.

* Targets cannot have the empty string as their name any longer.

* ant.jar's manifest does no longer include a Class-Path entry, so it
  is no longer possible to run Ant via "java -jar ant.jar" without
  manually altering the CLASSPATH.  Instead of that a file
  ant-bootstrap.jar is included in the etc directory of the binary
  distribution, copy this to the lib directory and use
  "java -jar ant-bootstrap.jar" instead if you want to run Ant without
  the wrapper script (not recommended).

* The <script> task now requires Apache BSF instead of the older IBM
  version.  See <http://jakarta.apache.org/bsf/>

* <xmlproperty> will no longer fail if the file to be loaded doesn't exist.

* XML namespaces are now enabled in the XML parser, meaning XML namespace
  declarations no longer cause errors. However task names containing colons
  will cause errors unless there is a corresponding namespace uri.

* The <ftp> and <telnet> tasks now require Jakarta Commons Net instead
  of the older ORO Netcomponents version.  See
  <http://jakarta.apache.org/commons/net/index.html>.

* <input> will no longer prompt the user and wait for input if the
  addproperty attribute is set to a property that has already been
  defined in the project.  If you rely on the task waiting for input,
  don't use the addproperty attribute.

* The Class-Path attribute in manifests will no longer merge the
  entries of all manifests found, but will be treated like all other
  manifest attributes - the most recent attribute(s) will be used.

* New Launch mechanism implemented. This moves some functionality from
  the batch files / shell scripts into Java. This removes environment
  limitations, for command issues, directory depth issues on Windows. Also
  allows a per-user library location to be used if the main Ant install
  is locked down.

* The Entry nested element of PropertyFile will not any more have its value
  attribute (actually increment) overwritten with the new value of the entry
  after execution.

* Output stored from a <java> or <exec> task is now exactly as generated. No
  conversion to platform end-of-line characters is performed.

* <translate> will now preserve line endings.

* <ftp> followsymlinks="false" in nested fileset definitions is explicitly
  required in order to exclude remote symbolic links (when doing a get, chmod,
  delete, rmdir).

* The values of the Copy#fileCopyMap variable has changed from String to
  String[]. (In java 1.5 terms it was Hashtable<String, String> and
  is now Hashtable<String, String[]>). This will affect third party code
  that extend Copy and override Copy#doFileOperations.

* <loadproperties> didn't expand properties while <property file="..."/>
  does, so they were not equivalent.  This has been fixed, which means
  that propetries may get expanded twice if you use an
  <expandproperties> filterreader.  Bugzilla Report 17782.

* User defined tasks and typedefs are now handled internally in the
  same way as predefined tasks and typedefs. Also tasks and typedefs
  are resolved at a later stage. This causes some
  differences especially for user defined task containers.

* <checksum> log message "Calculating checksum ..." has been degraded
  from INFO to VERBOSE.

Fixed bugs:
-----------
* Filter readers were not handling line endings properly.  Bugzilla
  Report 18476.

* Filtersets were also not handling line endings properly.

* Expand tasks did not behave as expected with PatternSets.

* <property environment=... /> now works on OS/400.

* <cab> could hang listcab on large <fileset>s.

* The starteam stcheckout, stcheckin tasks now correctly compute
  status of files against whatever local tree they are run against
  and, optionally, will not process a file if it is current.
  Previously you had to process everything unless you ran against the
  default folder which wasn't the normal use-case for ant-starteam.
  The stlist task now similarly displays that status correctly making
  it a more generally useful tool.

* entity includes would cause exceptions if path names included spaces.

* addConfiguredXXX would not work for TaskAdapter wrapped tasks

* Fix <ilasm> outputfile testing so that the output file does not need
  to exist beforehand.

* Ant will now exit with a return code of 1 if it encounters problems
  with the command line arguments.

* ClassLoader creation changes to use a factory method in Project. A new
  class AntClassLoader2 implemented for 1.2+ specific features including
  Package information and addition of classes specified in the Class-Path
  element of a Jar's manifest.

* It is now possible in <exec> to resolve the executable to a project
  basedir or execution dir relative executable. The resolveExecutable
  must be used to pick up such executables.

* splash screen wouldn't disappear when build was finished.

* <exec> output and error streams can now be redirected independently
  to either a property or a file (or both)

* TarEntry's File-arg constructor would fail with a
  StringIndexOutOfBoundsException on all OSes where os.name is shorter
  than seven characters.  Bugzilla Report 18105.

* <copy> and <move>'s failonerror didn't apply to filesets pointing to
  non-existant directories.  Bugzilla Report 18414.

* The <stripjavacomments> filter sometimes removed parts of string
  constants.  Bugzilla Report 17441.

* <antlr> will now recompile your grammar if the supergrammar has
  changed.  Bugzilla Report 12691.

* <property env> will now work on Unices with /bin/env instead of
  /usr/bin/env.  Bugzilla Report 17642.

* <jar index="on"> could include multiple index lists.  Bugzilla 10262.

* The index created by <jar> didn't conform to the spec as it didn't
  include the top-level entries.  Bugzilla Report 16972.

* <tar> and <zip> didn't honor the defaultexcludes attribute for the
  implicit fileset.  Bugzilla Report 18637.

* The <replacetokens> filter would throw an exception if the token's
  value was an empty string.  Bugzilla Report 18625.

* Perforce tasks relying on output from the server such as <p4change>
  and <p4label> were hanging. Bugzilla Reports 18129 and 18956.

* Improve exception and logging behavior of Perforce tasks.
  Bugzilla report 18154.

* build.sh install had a problem on cygwin (with REALANTHOME).
  Bugzilla Report 17257

* <replaceregexp> didn't work for multi-byte encodings if byline was false.
  Bugzilla Report 19187.

* <replaceregexp> was altering unnecessarily the timestamp of the directories
  containing the files to process
  Bugzilla Report 22541.

* file names that include spaces need to be quoted inside the @argfile
  argument using forked <javac> and (all JDKS).  Bugzilla Report 10499.
  NB : a first correction was only introducing quotes for JDK 1.4
  It has been changed to quote for all external compilers when paths
  contain spaces.
  Also the backslashes need to be converted to forward slashes
  Bugzilla Report 17683.

* Setting filesonly to true in <zip> and related tasks would cause the
  archives to be always recreated.  Bugzilla Report 19449.

  replacing in files that are in a different encoding than the
  platform's default.

* The <exec> task may now have its input redirected from either a file
  or a string from the build file. The error output can be separated
  to a different file when outut is redirected. standard error may be
  logged to the Ant log when redirecting output to a file

* The <java> task also supports the input redirection and separate
  error streams introduced to the <exec> task. In addition, it is now

  mono or other implementations -<csc> has been tested with Mono on
  Linux and OSX.


Changes from Ant 1.5.3 to Ant 1.5.4
===================================

Changes that could break older environments:
--------------------------------------------

* If the Visual Age tasks used to work for you, they may stop doing so
  now - and we'd like to know about it.  The current set of tasks is
  supposed to work with any version of VAJ starting with 3.0.

Fixed bugs:
-----------

* The Visual Age for Java tasks didn't work (at least for versions 3.0
  and higher).  Bugzilla Report 10016.

* URL-encoding in <vaj*port> didn't work properly.

* VAJRemoteUtil called getAbsolutePath instead of getPath
  causing problems when using a Windows VAJ server from a UNIX server.
  Bugzilla Report 20457.

* VAJImport task failed with NullPointerException when using DirectoryScanner.
  Bugzilla Report 22080.

Other changes:
--------------

* Shipped XML parser is now Xerces 2.5.0

* <javah> will invoke oldjavah on JDK 1.4.2.  Bugzilla Report 18667.

* The VAJ tasks now support a haltonfailure attribute to conditionally
  keep building even if they fail.

* It is now possible to use the latest (versioned or unversioned) edition
  in <vajload> by using special wildcard characters.  Also fixes
  Bugzilla Report 2236.

Changes from Ant 1.5.2 to Ant 1.5.3
===================================

Changes that could break older environments:
--------------------------------------------

* The <zip> task and friends have again changed a method signature
  (sorry, was necessary to fix bug 17780).  The return type of
  getResourcesToAdd has changed.

Fixed bugs:
-----------

* <zipfileset>'s filemode would get ignored and the dirmode was used
  for the included files as well.  As a side effect, WinZIP was unable
  to extract or display the files, so they seemed to be missing from
  the archive.  Bugzilla Report 17648.

* <ftp> could use the wrong path separator when trying to change the
  remote working directory.  Bugzilla Report 17735.

* <jar update="true"> would loose all original files if you didn't
  specify any nested <(zip)fileset>s and the manifest had changed.
  Bugzilla Report 17780.

* If you used a value starting with \ on Windows for the appxml
  attribute of <ear> or the webxml attribute of <war>, it would be
  ignored.  Bugzilla Report 17871.

* Ant will no longer implicitly add Sun's rt.jar in <javac> when you
  use jvc and don't specify a bootclasspath.  Bugzilla Report 18055.

* The prefix attribute of <zipfileset> would not generate directory
  entries for the prefix itself.  Bugzilla Report 18403.

* starteam checkout can now handle deleted labels.  Bugzilla Report 17646.

* The Unix wrapper script failed if you invoked it as a relative
  symlink and ANT_HOME has not been set.  Bugzilla Report 17721.

Other Changes:
--------------
* Added ability to specify manifest encoding for the <jar> and
  <manifest> tasks

Changes from Ant 1.5.1 to Ant 1.5.2
=============================================

Changes that could break older environments:
--------------------------------------------
* ANT_OPTS environment variable is now applied at the start of the
  Java command line, allowing position specific parameters of some
  JVMs, such as -classic to be specified.

* ZipScanner#getIncludedFiles will now return the names of the ZipEntries
  that have been matched instead of the name of the archive.

* The <zip> task and friends have been heavily modified, almost every
  method signature of the Zip class has changed.  If you have subclassed
  Zip (or one of its subclasses), your class will most likely not
  compile against the current code base.  If it still compiles, it will
  probably not work as in Ant 1.5.1.

Fixed bugs:
-----------
* <translate> was not ignoring comment lines.

* <manifest> wouldn't update an existing manifest if only an attribute
  of an existing section changed.

* ant.bat now supports the ANT_ARGS and JAVACMD environment variables
  again (like Ant 1.5 did).

* The "plain" <junit> <formatter> could throw a NullPointerException
  if an error occurred in setUp.

* <junit> will now produce output when a test times out as well.

* <replace> would count some internal character replacements when
  reporting the number of replaced tokens.

* <concat> would cause an exception if a <filelist> pointed to files
  that do not exist.

* <javadoc> will now pass -source to custom doclets as well.

* <cvstagdiff> would throw a NullPointException if there had been no
  differences.

* <cvschangelog> could miss today's changes.

* <concat> could append newline characters between concatenated files.

* <xmlvalidate> ignored the specified encoding of the files to
  validate.

* the errorsbeginat attribute of the <http> condition didn't work.

* Ant will try to force loading of certain packages like com.sun.*
  from the system classloader.  The packages are determined by the
  version of the JVM running Ant.

* Ant didn't find the runtime libraries on IBM's JDK 1.4 for Linux.

* random component of temporary files is now always a positive integer.

* Ant could incorrectly try to use the 1.4 regexp implementation even
  if it isn't available if you run the JVM with -Xverify:none.

* Ant would die with an exception if you used nested <reference>
  elements in Ant and the refid attribute didn't point to an existing
  project reference.

* The <get> task can now be compiled (and Ant thus bootstrapped) using
  Kaffee.

* build.sysclasspath will now be honored by more tasks.

* The signjar keystore attribute has been reverted to a String allowing
  it to once again accept URLs. This should not affect current File based usage
  unless you are extending the Signjar task.

* <jar update="true"> would remove the original manifest.

* fix up folder creation in PVCS task

* <tar>'s up-to-date check didn't work for nested <(tar)fileset>s.

* Corrected a problem in XMLLogger where it would not associated
  messages with a taskdef'd task

* <uptodate> now works when using attributes (i.e. not filesets) and pointing
  to the same file

* Java task (and output system) now stores output which doos not end
  with a line feed.

* splash screen wouldn't disappear when build was finished.

* <exec> now supports OS/2.

* <zip> and friends would only update/recreate existing archives if
  the files to add/update have been newer than the archive.

* <javadoc>'s <link> element could fail for offline="true" on some JDKs.

Other changes:
--------------

* MailLogger now sets the Date header correctly.

* Shipped XML parser is now Xerces 2.3.0

* signjar now accepts a maxmemory attribute to allow the memory allocated to the
  jarsigner tool to be specified. The jarsigner from the JDK's JAVA_HOME bin
  dir is now used rather than the first jarsigner on the path.

* **/.DS_Store has been added to the list of default pattern excludes.

* The Created-By header in the default manifest now contains the JVM
  vendor and version according to the jar specification. A new header,
  Ant-Version provides the Ant version used to create the jar.

* <zip> can now store Unix permissions in a way that can be
  reconstructed by Info-Zip's unzip command.

Changes from Ant 1.5.1Beta1 to 1.5.1
====================================

Fixed bugs:
-----------

* <tstamp>'s prefix attribute failed to apply to nested <format> elements.

* <junitreport> created an empty junit-noframes.html if no format had
  been specified.

* <basename> would remove more than it should if the file name
  contained more than one dot.

* <filterset>s nested into <filterset>s didn't work.

Other changes:
--------------

* Shipped XML parser is now Xerces 2.2.0

* Filesets now support a 'file' attribute, allowing a single-file
  fileset to be constructed without having to specify its parent
  directory separately.

* <junit> will now return the result of a call to getName instead of
  "unknown" for Test implementations that don't extend TestCase but have
  a public String getName() method.

Changes from Ant 1.5 to 1.5.1Beta1
==================================

Fixed bugs:
-----------
* Date/time in CvsChangeLog was in local timezone and 12 hour format leading
  to a problem when sorting by time. It is now UTC (GMT) and in 24-hour
  format as per cvs 'specifications'.

* CvsTagDiff now supports ampersand modules or modules that have a different
  root directory than their name.

* EjbJar threw NPEs for the Websphere element. The property 'websphere.home'
  was not documented.

* Mail example in the documentation was not correct.

* Checksum was broken in the following scenario:
  (using verifyproperty OR in a condition) AND using filesets
  with multiple files.

* The ExpandProperties filter threw NPEs when defined using
  the <filterreader> format.

* The sh wrapper script didn't work under Cygwin if ANT_HOME wasn't
  set with a Unix style filename.

* The sh wrapper script could fail if you started Ant from a directory
  with whitespace in its name.

* ant -diagnostics was not working properly when the task dependency
  was missing and was just printing the missing dependency.

* If a task got redefined via <taskdef>, it lost its child elements.

* <property>'s classpathref attribute was broken.

* <arg line="''" /> would result in no command line argument, will now
  be a single empty argument.  Use <arg value="''"/> if you need the
  quotes literally.

* <replaceregexp> could append a newline character at the end of the
  file.

Other changes:
--------------

* Appendix E of Java Development with Ant (Loughran/Hatcher) was
  contributed to the docs.

* <available> will only print deprecration warnings if it is actually
  used to change the value of a property.

Changes from Ant 1.5beta3 to Ant 1.5
====================================

Changes that could break older environments:
--------------------------------------------

* The filesetmanifest attribute added to <jar> after the 1.4.1
  release has been removed for now.  This change may affect only
  the 1.5Beta/1.6Alpha users.  An attempt will be made to add this
  feature back into Ant 1.6.

Fixed bugs:
-----------

* <zip> and friends would always update existing archive if you set
  the update attribute to true.

* To support backward compatibility with older versions, <pathconvert>
  will once again set the property, even if the result is the empty
  string, unless the new 'setonempty' attribute is set to false|no|off
  (default is "true").

* The manifest task would crash XmlLogger

Other changes:
--------------

* added **/.svn and **/.svn/** to the default excludes

Changes from Ant 1.5beta2 to Ant 1.5beta3
=========================================

Changes that could break older environments:
--------------------------------------------

* <pvcs> default filenameformat has been different from Ant 1.4.1.
  Now it is different from 1.5beta1 and 1.5beta2.

* <pathconvert> won't set the property if the result is the empty string.

Fixed bugs:
-----------

* <available> could fail to find files or directories that happen to
  start with the name of the project's basedir but are not children of
  the basedir.

* Nested <property>'s inside <ant> can now be overriden by subsequent
  <ant> and <antcall> tasks.

* <xslt>'s outputtype attribute wouldn't do anything.

* <linecontains> filterreader could swallow lines.

* <sequential> used to configure the tasks (set their attributes)
  before the first task has been executed.  This means that properties
  that have been set by nested task seemed to be unset for the other
  tasks in the same <sequential> element.

* <javac>'s sourcepath setting has been ignored by some compiler
  implementations.

* <javadoc>'s packagelist attribute didn't work.

* the plain mailer would always use port 25 in <mail>.

* Ant's default logger could swallow empty lines.

* ejbjar's iPlanet nested element now can process multiple descriptors.

* IPlanetEjbc was looking in the wrong place for four iiop files.

* <javac> would pass the -source switch to JDK 1.3's javac, even
  though it doesn't support it.

Other changes:
--------------

* <checksum> now uses a buffer (of configurable size).

* The "Trying to override task definition" warning has been degraded
  to verbose level if the two task definitions only differ in the class
  loader instance that has loaded the definition.

* Add a jvmargs to the ejbjar's weblogic element to allow additional
  arguments to be provided to the VM runnign ejbc. Document the
  jvmdebuglevel attribute which can be used to avoid warnings about
  interface classess being found on the classpath. Document the new
  <sysproperty> element which allows JVM properties to be defined.
  Added an outputdir attribute to allow the destination to be a
  directory into which the exploded jar is written.

* ejbjar now supports Borland Enterprise Server 5 and Jonas 2.5

Changes from Ant 1.5beta1 to Ant 1.5beta2
=========================================

Changes that could break older environments:
--------------------------------------------

* Properties will now be expanded in mail message bodies.  This means
  that one $ sign will be stripped if your mail message contains the text $$.

* org.apache.tools.ant.taskdefs.Expand no longer extends MatchingTask.

* Available#setFile now again uses a File argument as it did in 1.4,
  this may break environments that have been adapted to the String
  argument version present in 1.5beta1.

Fixed bugs:
-----------
* When <move> attempts a rename, it deletes the destination file, if it
  exists, before renaming the source file.  However, <move> was not
  checking if the destination file was actually a directory before
  trying to delete it.

* Make CVS Tasks to work under Cygwin.

* Fix LineContains to handle huge files elegantly without causing
  Stack Overflows.

* if you ask for the "classic" compiler on Java1.4, you get upgraded to
  "modern" because there is no classic compiler any more.

* the <http> condition was viewing 404 'not found' exceptions as success. Now
  it defaults to viewing any response >=400 as an error, and has an
  errorsBeginAt attribute you can use if you want a higher or lower value.

* <get> throws a build exception on an http authorization error, unless you
  have set ignoreerrors to true.

* <wsdltodotnet> was spelt in Wintel case: <WsdlToDotnet>. It is now lower
  case, though the old spelling is retained for anyone who used it.

* Merging of Manifests in jar now works as documented.

* paths that have been separated by colons would be incorrectly parsed
  on NetWare.

* runant.pl now supports NetWare.

* <tempfile> and <setproxy> tasks were in beta1, but not defined by
  default; They now are. <tempfile> fills a property with the name of a
  temporary file; <setproxy> lets you set the JVM's http, ftp and socks proxy
  settings.

* <available classname="foo" ignoresystemclasses="true"> failed for
  JDK 1.1 and 1.2, even if the class could be found on the
  user-specified classpath.

* <property environment=... /> now works on z/OS.

* forked <javac> failed for the wrong reason on JDK 1.1 - Ant would
  use a temporary file to hold the names of the files to compile under
  some conditons, but 1.1 doesn't support this feature.  Ant will no
  longer try this, but you may run into problems with the length of the
  command line now.

* the refid attribute for <property>s nested into <ant> or <param>s
  nested into <antcall> didn't work.

* <replaceregexp> didn't work for nested <fileset>s.

* <javadoc> dropped sourcepath entries if no "interesting" .java
  source files  could be found below them.  This has been backwards
  incompatible and caused problems with custom doclets like xdoclet.

* Using the doclet, docletpath or docletpathref attributes of
  <javadoc> may have caused NullPointerExceptions.

* nested <filesets> of <javadoc> would include too much.

* <dependset> will no longer choke on <targetfileset>s that point to
  non-existing directories.

* <patch> didn't work at all.

* <replace> and <replaceregexp> now fail if the file they are working
  on is locked.

* <javadoc> would pick up the wrong executable in the combination JDK
  1.2 and AIX.

Other changes:
--------------

* z/OS now gets detected by the os condition.

* <fileset> and <dirset> now have an optional followsymlink attribute
  that can prevent Ant from following symbolic links on some platforms.

* BeanShell is now supported in the <script> task.

* <ejbjar> under Weblogic attempts to use the ejbc20 compiler for 2.0 beans
  based on the deployment descriptor's DTD reference. Under weblogic 7.00 Beta
  this ejbc class has been deprecated. To avoid the deprecation warning use
  ejbcclass="weblogic.ejbc".

* <ejbjar> will add a manifest to the generated jar based on the naming
  convention in use. This overrides the manifest specified in the
  <ejbjar> attribute


Changes from Ant 1.4.1 to 1.5beta1
==================================

Changes that could break older environments:
--------------------------------------------

* Important: Single $ signs are no longer silently stripped!
  Before you panic that we have broken all your build files, we have kept
  the old "$$" -> "$" behaviour. So only build files which accidentally had
  a $ sign in a string that was being silently stripped may break.
  We added this fix to stop newbie confusion; if you want to write a
  build file which works on ant versions 1.4.1 or earlier, stay with
  the double $$ sign rule.

* Project.getBuildListeners now returns a clone of the listener
  list. Changes to the returned list will not affect the listeners
  currently attached to the Project. It also means that it is safe to
  iterate over the returned list if listeners are added or removed
  during the traversal.

* <pvcs> default filenameformat has been different from Ant 1.4.1.

* Some messages that are printed during startup will not be
  written to the logfile specified via -logfile as they might destroy
  the format of the file for special BuildLoggers (like XmlLogger).

* The filesetmanifest attribute added to <jar> after the 1.4.1
  release has been removed for now.  This change may affect only
  the 1.5Beta/1.6Alpha users.  An attempt will be made to add this
  feature back into Ant 1.6.
* Shipped XML parser is now Xerces 2.0.1 along with the XML Parser APIs.
  XML Parser APIs is a separate jar that contains the necessary
  JAXP/DOM/SAX classes.

* <telnet> was fixed to expand properties inside nested <read> and
  <write> elements; before this only happened when you assigned the text
  to the string attribute. If you had $ signs in the string, they may
  need escaping.

* the RegexpMatcher interface has been extended to support case
  insensitive matches and other options - custom implementations of
  this interface won't work any longer.  We recommend to use the new
  Regexp interface that also supports substitution instead of the
  RegexpMatcher interface in the future.

* <gzip> will throw an exception if your src attribute points to a directory.

* Unjar, Unzip and Unwar will throw an exception if the Src attribute
  represents a directory.  Support for nested filesets is provided
  instead.

* It is no longer possible to overwrite a property using tasks like
  <condition>, <exec>, <pathconvert>, or <tstamp>. In some exceptional
  cases it will generate a warning if you attempt to overwrite an
  existing property.

* Taskwriters please note: Whenever tasks had any overloaded set* methods,
  Ant's introspection mechanism would select the last overloaded method
  provided to it by the Java Runtime.  A modification has now been made such
  that when the Java Runtime provides a method with a String as its argument,
  a check is made to see if there is another overloaded method that takes in
  some other type of argument.  If there is one such method, then the method
  that takes in String as an argument is not selected by the Introspector.

* The pattern definition **/._* has been included into the Default
  Excludes list.

* <propertyfile>'s <entry> element was modified to remove "never" as a value
  as its behavior was undocumented and flakey.

* The -projecthelp flag now only prints out targets that include the
  'description' attribute, unless the -verbose or -debug flag is included
  on the Ant command line.

* Ant's testcases now require JUnit 3.7 or above, as they now use the new
  assertTrue method instead of assert.

* If the 'output' attribute of <ant> is set to a simple filename or a
  relative path, the file is created relative to ${basedir}, not ${user.dir}.

* The default value for build.compiler is now javac1.x with x
  depending on the JDK that is running Ant instead of classic/modern.

Fixed bugs:
-----------

* <available> could fail to find files or directories that happen to
  start with the name of the project's basedir but are not children of
  the basedir.

* Nested <property>'s inside <ant> can now be overriden by subsequent
  <ant> and <antcall> tasks.

* <xslt>'s outputtype attribute wouldn't do anything.

* <linecontains> filterreader could swallow lines.

* <sequential> used to configure the tasks (set their attributes)
  before the first task has been executed.  This means that properties
  that have been set by nested task seemed to be unset for the other
  tasks in the same <sequential> element.

* <javac>'s sourcepath setting has been ignored by some compiler
  implementations.

* <javadoc>'s packagelist attribute didn't work.

* the plain mailer would always use port 25 in <mail>.

* Ant's default logger could swallow empty lines.

* ejbjar's iPlanet nested element now can process multiple descriptors.

* IPlanetEjbc was looking in the wrong place for four iiop files.

* <javac> would pass the -source switch to JDK 1.3's javac, even
  though it doesn't support it.

* <zip> and friends would always update existing archive if you set
  the update attribute to true.

* To support backward compatibility with older versions, <pathconvert>
  will once again set the property, even if the result is the empty
  string, unless the new 'setonempty' attribute is set to false|no|off
  (default is "true").

* The manifest task would crash XmlLogger

* A bug existed that prevented generated log files from being deleted as
  part of the build process itself.  This has now been fixed.

* Fixed bug where <move> ignored <filterset>s.

* Ant works properly with the combination of Java1.4/WindowsXP.

* Fixed bug where <java> used to sometimes invoke class constructors twice.

* Fixed bug with 4NT shell support.

* Fixed bug where ant would not perform ftp without remotedir being
  specified even though this was not mandatory.

* Fixed bug where ant would not copy system properties into new Project
  in ant/antcall tasks when inheritall="false" is set.

* <propertyfile> would not close the original property file.

* <ant> will no longer override a subbuild's basedir with inheritall="true".

* Fixed problem with the built-in <junit> formatters which assumed
  that only one test could be running at the same time - this is not
  necessarily true, see junit.extensions.ActiveTestSuite.

* <jar>'s whenEmpty attribute is useless as JARs are never empty, they
  contain at least a manifest file, therefore it will now print a
  warning and do nothing.

* <typedef> hasn't been all that useful as it couldn't be used outside
  of targets (it can now) and nested "unknown" elements have always
  been considered to be tasks (changed as well).

* <fixcrlf> would fail for files that contained lines longer than 8kB.

* Some junit formatters incorrectly assumed that all testcases would
  inherit from junit.framework.TestCase.

* <fixcrlf> dropped the first characters from Mac files.

Other changes:
--------------

* <checksum> now uses a buffer (of configurable size).

* The "Trying to override task definition" warning has been degraded
  to verbose level if the two task definitions only differ in the class
  loader instance that has loaded the definition.

* Add a jvmargs to the ejbjar's weblogic element to allow additional
  arguments to be provided to the VM runnign ejbc. Document the
  jvmdebuglevel attribute which can be used to avoid warnings about
  interface classess being found on the classpath. Document the new
  <sysproperty> element which allows JVM properties to be defined.
  Added an outputdir attribute to allow the destination to be a
  directory into which the exploded jar is written.

* ejbjar now supports Borland Enterprise Server 5 and Jonas 2.5

* added **/.svn and **/.svn/** to the default excludes.

* Selector Elements now provide a way to create filesets based on
  sophisticated selection criteria.

* Gzip and Bzip2 files can now be constructed in the fly when using
  the tar task without having to create the intermediate tar file on
  disk.  The Untar task can also untar GZip and BZip2 files on the fly
  without creating the intermediate tar file.

* New optional type, <classfileset> added.

* <ejbjar> now allows control over which additional classes and interfaces
  are added to the generated EJB jars. A new attribute "dependency" can be
  defined which controls what classes are added. The addition of classes now
  uses the Jakarta-BCEL library rather than reflection, meaning bean classes are
  no longer loaded into Ant's JVM. The default dependency analyzer is known as
  the ancestor analyzer. It provides the same behaviour as the 1.4.1 version of
  <ejbjar>. If the BCEL library is not present, a warning will be issued stating
  the ancestor analyzer is not available. In this case <ejbjar> will continue
  to function but will not add super classes to the jar.

* <available> has a new attribute named ignoreSystemClasses.

* New task <cvschangelog/> generates an XML report of changes that occur
  on CVS repository.

* New filter readers: ClassConstants, ExpandProperties, HeadFilter,
  LineContains, LineContainsRegExp, PrefixLines, ReplaceTokens,
  StripJavaComments, StripLineBreaks, StripLineComments, TabsToSpaces,
  TailFilter.

* <copy>, <loadfile>, <loadproperties>, <move> support FilterChains
  of FilterReaders.

* New task <loadproperties> to load contents of file as Ant properties,
  with nested <filterchain> elements.

* New task <loadfile> to load a whole file into a property.

* New task <echoproperties> to list your current properties to the screen
  or a file.

* New tasks <bzip2> and <bunzip2> to pack and unpack files using the
  BZip2 alogrithm.

* New tasks <replaceregexp>, <checksum>, <translate>, <waitfor>,
  <manifest>, <vsscp>, <vssadd>, <vsscreate>, <splash>, <basename>, <dirname>,
  <concat>, <sourceoffsite>, <jarlib-available>, <jarlib-display>,
  <jarlib-manifest>, <jarlib-resolve>.

* A new combined <mail> task, which replaces the old <mail> and
  <mimemail> tasks, has been added.  The <mimemail> task, and
  old SendEmail and MimeMail classes have been deprecated.

* Mail task allows specification of port number.

* Users can control what <zip> and <jar> must do when duplicate files
  are found.  A new element <zipgroupfileset> allows for multiple zip
  files to be merged into the archive.  In addition, <jar> also has
  another new attribute: filesetmanifest.  The existing manifest
  attribute of <jar> now also accepts the name of a jar added through
  a fileset.

* gzip now checks that the zipfile is older than the source file
  before rebuilding the zipfile.

* TarFileset takes in three new attributes - fullpath, prefix
  and preserveLeadingSlashes.

* <move> attempts to rename the directory, if everything inside it is
  included, before performing file-by-file moves.  This attempt will
  be done only if filtering is off and if mappers are not used.  This
  is a performance improvement and there is no change otherwise in
  the functionality of this task.

* Exec task has extra attribute "resultproperty" to get the return code
  into a property.

* Exec task prints a message when a timed-out process is killed.

* Added optional attributes - name, arch and version to the <os> task.

* Unjar, Untar, Unwar and Unzip now support patternsets to
  select files from an archive for extraction.  Filesets may be
  used to select archived files for unarchival.

* Javac task allows debug levels to be specified.  Debug levels
  will have an effect only when the modern compiler or the
  classic compiler (version 1.2 and higher) is used and debugging
  is enabled.

* Added support for specifying CVS_RSH in the <cvs/> task

* The attributes zipfile, jarfile, warfile and earfile (from the Zip,
  Jar, War and Ear tasks) have been deprecated and superseded by a
  new attribute "destfile".

* Added new conditions <isset>, <checksum>, <http>, <socket>, <contains>,
  <filesmatch>.

* <taskdef> and <typedef> will now emit a warning if a task/type of
  the given name already exists.

* A new revision of VAJ tasks: The most important new feature
  is the ability to execute VAJ tasks from the command line by
  exploiting the Remote Tool Access feature of VAJ.

* Improved support for Novell NetWare.

* Added an optional encoding attribute to <fixcrlf>.

* <apply> has a new attribute relative that allows users to pass the
  filenames as relative instead of absolute paths on the command line.

* References can now be copied into the child build by <ant> and
  <antcall> using nested <reference> elements or the new inheritRefs
  attribute.

* <fail> now supports builds to fail based on conditions via if and
  unless attributes.

* Ant now comes with two new BuildLogger implementations - one that
  can send emails containing a log of the build process (MailLogger),
  and one that colorizes the output based on message levels, using
  ANSI color code escape sequences (AnsiColorLogger).

* A "package" mapper type has been added to allow package directory
  names replaced with the dotted form.

* You can now specify environment variables in the <java> and <junit> tasks
  if the fork attribute has been set to true.

* -propertyfile command-line option has been added to load an entire
  property file just as -D properties are declared (as user properties).
  -D properties take precedence over -propertyfile specified ones.

* You can now set an ANT_ARGS environment variable to hold arguments you
  always want passed to the 'ant' command -- for example, if you always
  want to use a different logger or the -find flag.

* <tstamp> now supports a new "prefix" attribute to prefix properties set.

* You can now specify the -sourcepath for <javac> explicitly.

* <javac> now supports a new "listfiles" attribute to list the source
  files it's handing off to the compiler.

* The compiler implementation for <javac> can now be chosen on a task by
  task basis.  The new "compiler" attribute of <javac> can be used to override
  the value of the build.compiler property, if set.

* <javac> has a new nested element, <compilerarg>, which allows you
  to specify additional args for the specific compiler you're using.

* <javac>'s "source" attribute is now enabled for jikes as well.

* <propertyfile>'s <entry> now has a 'unit' attribute to specify the
  increment/decrement unit on date operations.

* <property> now supports a 'prefix' attribute when loading from a file
  or resource.

* In Ant 1.4, a feature has been added to the <junit> task that would
  add ant.jar, optional.jar and junit.jar implicitly to the classpath -
  this feature can now be disabled by setting the new includeantruntime
  attribute to false.

* <style> behaves differently from any other directory-based task, as it
  processes all files that it finds in included directories in
  addition to the files matched by your patterns.  There is now a new
  attribute, 'scanincludeddirectories', to suppress this behavior.

* <javadoc> now supports a <tag> nested element to provide the -tag option
  to the standard Java 1.4 doclet. The element is ignored when not running
  on Java 1.4.

* <ftp> can now chmod files on a remote server that supports
  "site chmod", as well as set the umask before transferring files, if
  the server supports "site umask".

* New <serverdeploy> "optional" task.

* <patternset> now supports nested patternsets.

* Perforce tasks now support a "failonerror" attribute (defaults to "true").

* Open Source application server JOnAS support:
    EJB hot deploy and deploy with <serverdeploy> and <ejbjar>

* Added new DirSet (<dirset>) datatype.

* <path> now supports nested <dirset> and <filelist> elements.

* <pathconvert> now supports nested <dirset> and <filelist> elements.

* <pathconvert>'s "dirsep" and "pathsep" attributes now accept
  multi-character values.

* <copy> task now has a 'failonerror' attribute to allow keep-going
  behaviour when the file to be copied is not found (defaults to "true").

* <uptodate> now has a 'srcfile' attribute to allow specifying a
  full-path filename.

* <exec>, <sql> and <java> now support append attributes to allow
  appending the output to an existing file.

* <java> now supports a timeout attribute analog to <exec> - it is
  highly recommended to only use it together with fork="true".

* <javadoc> now supports a source attribute to enable javadoc to
  handle assertions present in JDK 1.4 source code.

* <replace> supports a new replacefilterfile attribute that
  automatically turns all properties of a given file into
  replacefilters.

* An alias of <xslt> has been added to refer to the <style> task.

* The compiler implementation for <rmic> can now be chosen on a task by
  task basis.  The new "compiler" attribute of <rmic> can be used to override
  the value of the build.rmic property, if set.

* <rmic> has a new nested element, <compilerarg>, which allows you
  to specify additional args for the specific compiler you're using.

* org.apache.tools.ant.XmlLogger now is a BuildLogger, rather than just
  a BuildListener. It can operate in either mode successfully.

* <junit> has a new attribute "showoutput".  If set to true, output
  generated by tests will be sent to Ant's logging system as well as
  to the formatters (instead of sending it to the formatters
  exclusively).

* Ant has now a pluggable way to prompt users for input, which is used
  by the new <input> task.  IDE integrators can provide an
  implementation of the InputHandler interface to decouple Ant's input
  from the console.  An implementation that gets its input from a file
  for unattended builds is part of Ant's distribution.

  For more details see docs/manual/inputhandler.html.

* <patch> has a new attribute that selects the directory in which to
  run the command.

* <javadoc> now supports two new nested elements, <fileset> and <packageset>.


Changes from Ant 1.4 to Ant 1.4.1
===========================================

Fixed bugs:
-----------

* <ant>'s antfile attribute will now also be considered an absolute path on
  Windows systems, if it starts with a \ and no drive specifier.

* The fullpath attribute of <zipfileset> has been ignored if you used
  the src attribute at the same time.

* The manifest file is now always placed as the second entry (after /META-INF)
  in generated jars. This allows the manifest to be read by JarInputStreams

* Fixed bug in depend task which would fail with a NullPointerException if no
  dependency cache was specified.

* sql task now handles REM statements correctly so that lines starying with rem
  but which are not comments are actually processed.

* XMLLogger now uses the task's name rather than the classname

* <mapper>s will now work as expected if the to pattern expands to an
  absolute pathname.

* <javac> didn't ignore memory settings in non-fork mode

* <cab> didn't split the options attribute into several command line
  arguments correctly.

Other changes:
--------------

* New source attribute for <javac> to enable assertion in JDK 1.4

* XmlLogger and <antstructure> now add an encoding declaration to the
  XML files they generate.

* <fileset> has a new attribute "casesensitive" to make it match
  filenames in a case insensitive way (if you set it to false) - by
  default filesets remain case sensitive.

Changes from Ant 1.3 to Ant 1.4
===========================================

Changes that could break older environments:
--------------------------------------------
* JUnitReport now uses the xalan redirect extension for multi-output.
  With Xalan 1.2.2 it forces the use of bsf.jar in the classpath.
  (Available in the xalan distribution). It is recommended to switch
  to Xalan 2.x that do not need it.

* Zip.setWhenempty() has changed its signature.

* <rmic> is now implemented using a factory. This makes extending
  rmic to use a new compiler a lot easier but may break custom
  versions of this task that rely on the old implementation.

* several Zip methods have changed their signature as we now use a Zip
  package of our own that handles Unix permissions for directories.
  Furthermore <zip> will now use the platform's default character
  encoding for filenames - this is consistent with the command line
  ZIP tools, but causes problems if you try to open them from within
  Java and your filenames contain non US-ASCII characters. Use the new
  encoding attribute of the task and set it to UTF8 to get the old
  behavior.

* The <pvcs> task has been moved to a package of its own.

* JUnitResultFormater has two additional methods that must be
  implemented by custom formatters.

* Ant will no longer use the canonical version of a path internally -
  this may yield different results on filesystems that support
  symbolic links.

* The output generated by the xml formatter for <junit> has changed
  again, it doesn't format the numeric value in the time attribute anymore.

* Pattern matching rules have changes slightly, the pattern foo*
  doesn't match files contained in a directory named foo - use foo/*
  instead.

* <fixcrlf> will not remove trailing whitespace at the end of lines anymore.

* The Classloader usage has been changed for the taskdef, property, available
  and sql tasks so that it delegates to the parent classloader. This may cause
  ClassNotFoundExceptions to be thrown if a system class attempts to load a
  class in the taskdef's classpath (typically factory objects).

* Ant now allows multithreading of tasks and the containment of tasks within
  other tasks. This can break customer listeners which do not expect messages
  from a task before the previous task has finished.

* Ant now installs its own ouput stream into System.out to route output to the
  task currently executing on the current thread. This also means that all
  output is now routed as Ant message events. Customer listeners and loggers
  should not call System.out at any time. This has always been true but such
  usage now will cause problems due to possible recursion.

* Invalid manifest files will now cause build failures in the <jar> task.

* Ant Introspection now looks for methods with method names starting with
  addConfigured. When called these methods are passed an argument after it has
  been configured from the build file. Custom tasks supporting nested elements
  starting with the name configured will no longer function.

* The environment variable JAVACMD that can be used to specify the
  java executable to Ant's wrapper scripts must not contain additional
  command line parameters any longer - please use the environment
  variable ANT_OPTS for such parameters now.

* Ant's wrapper scripts now quote the CLASSPATH environment variable, thus
  supporting classpaths which refer to directories containing spaces. This means
  that the CLASSPATH environment variable cannot have quotes. Any quotes should
  be removed. This will not affect the operation of the CLASSPATH environment
  variable in other contexts.

* A delete task like
  <delete includeEmptyFilesets="true">
    <fileset dir="somedir" />
  </delete>
  will now remove "somedir" as well, unless there are still files left
  in it (matched by the default excludes).

* The copy task will now fail if the file to be copied is not found.

* Ant properties defined in properties files now behave the same way as
  properties defined in the build file. In particular the $ character needs
  to be escaped in property values by doubling it to $$. So, to define a
  property with the value $hello, you need to define it in a properties file
  as
    test.prop=$$hello
  This was not the case in Ant 1.3

Other changes:
--------------

* New tasks: ear, p4counter, record, cvspass, vsscheckin, vsscheckout,
  typedef, sleep, mimemail, set of tasks for Continuus/Synergy, dependset,
  condition, maudit, mmetrics, jpcoverage, jpcovreport, jpcovmerge

* Ant now uses JAXP 1.1

* rmic now supports Kaffe's and Weblogic's version of rmic.

* <fixcrlf> won't override files that are already in the correct
   format.

* <sql> now supports REM comments as well as // and --

  <war>'s <webinf>.

* <pvcs> can now handle multiple projects.

* <available> now has a "type" attribute you can use in conjunction
  with the "file" attribute to specify whether the "file" you're
  looking for is a file or a directory.

* New <junit> formatter named "brief"

* <ejbjar> changes
  * Add support for Borland Application Server to the <ejbjar> task using
    a <borland> nested element.
  * Add support for iPlanet Application Server to the <ejbjar> task. Also
    includes some iPlanet utility tasks
  * Add support for JBoss Application Server to the <ejbjar> task.
  * Add a naming attribute to control the naming scheme that
    ejbjar uses to name the generated EJB jars.
  * Weblogic element now sets the compiler class for EJB 2.0 beans
  * <dtd> elements can be specified at the <ejbjar> level for building generic
    beans
  * <dtd> elements can now be URLs
  * Allow the manifest to be specified for the generated jars
  * The weblogic element now supprts an attribte noEJBC to skip the processing
    of the jar by ejbc. The ejbc step will then occur at deployment
  * weblogic will tell ejbc to use Jikes compiler if build.compiler is set to
    jikes. It can be restored to the default, javac, operation if desired.

* Allow the <sql> Delimiter to be set in the so that Oracle stored procs may be
  entered

* <execon> and <apply> can now optionally skip empty filesets.

* <javadoc> has a new useexternalfile attribute that makes it use a
  temporary file for sourcefile and package names - helps to defeat
  command line length limitations.

* Data types like <path> can now be defined inside of <target>s

* you can now specify a classpath for <style> - the XSLZ processor
  will be loaded from this path

* added a force attribute to <style> to support dependencies that the
  task cannot determine itself (dependency on parameters, not file
  modification times for example)

* added vmlauncher attribute to exec tasks. This defaults to true. If
  it is set to false, the VM's ability to launch commands in bypassed
  and the OS shell, either directly or through the auxillary antRun
  scripts is used.

* regexp mapper now supports the java.util.regex package of JDK 1.4.

* New filesonly attribute for <zip> and friends to suppress directory
  entries.

* New update attribute for <zip> and friends - update an existing
  archive instead of creating a new one.

* <apply> and <execon> have been merged into a single task.

* added vssver.scc to the default excludes

* <available> has a new filepath attribute/nested element that allows
  you top search for a file in a given path.

* <junit> can now optionally set a property on test failure.

* <taskdef> can now define several tasks at once, reading the
  name/classname pairs from a property file or resource.

* <unzip/unjar/unwar> and <untar> now have an overwrite attribute that
  defaults to true.  If set to false, files that are newer than the
  files in the archive will not be replaced.

* <patternset> and <fileset> now support nested <in/excludesfile>
  elements - using these you can have more than one in/excludes file
  per <patternset>.

* Three new supported compilers for javac: kjc for kopi, gcj for the
  gcc frontend and sj for Symantec's compiler.
  In addition extJavac or the new fork attribute can be
  used to run the JDK's javac in a JVM separate from Ant.

* <fixrlf> can now with CR only line-ends and can use an arbitraty
  between 2 and 80.

* The .NET tasks have been adapted to the beta2 release of the framework.

* <move> will now try to rename() files before copying them byte by
  byte - only if filtering is of, of course.

* <ant> and <antcall> tasks now support a new attribute inheritAll. When set to
  false, only user properties are passed through to the target Ant instance.
  This includes properties set on the command line and properties explicitly
  passed

* <javadoc> now skips off line links if the package list cannot be found.

* <wlrun> now allows the security policy file to exist outside the weblogic
  directory.

* <java> task will set the Thread contextClassLoader under JDKs 1.2+ to the
  classloader for the class being executed.

* Introduce the concept of a TaskContainer - a task or element which can contain
  Ant Tasks.

* Add new tasks implementing the TaskContainer interface <parallel> and
  <sequential> which allow parallel execution of tasks to be specified.

* <depend> task will now take into account dependencies on jar files and class
  files from a given classpath.

* <jar> manifest entries may now be specified in the build file either
  completely or to be merged with a manifest file.

* <tstamp> task custom formats now support locales.

* Added a listner which will forward events to Log4J. The log4j configuration
  file should be in the directory from which Ant is run or passed as a system
  property using a JVM argument.

* Introduced the concept of <filtersets> to allow for more control in which
  filters get applied in a <copy> or <move> operation.

* Added nowarn attribute to javac and deprecated the Jikes-magic property
  build.compiler.warnings.

* The <depend> task cache format has changed and all dependency information is
  now stored in a single file.

Fixed bugs:
-----------

* Testcases have been made independent of current working directory.

* Input ZIP-Files will be closed when using a <zipfileset>.

* p4 tasks now don't fail if user, port or client have been omitted
  (and this is acceptable for the context of the command).

* <javah>'s outputfile attribute will be resolved as relative to the
  projects basedir.

* <antstructure> should create a valid DTD for propertyfile.operation.entry
  and omit tasks it fails to load.

* won't try to pass a -bootclasspath flag to javac 1.1 anymore

* <style>'s style attribute no handles absolute paths correctly.

* <delete includeemptydirs="true"> now deletes more than just the leaf
  directories.

* You can now specify a <fileset> for a directory that doesn't exist at
  declaration time but will created before the fileset gets used for the
  first time.

* If the quiet attribute has been set, <delete> will handle <fileset>s
  with non-existing directories gracefully.

* Output written by testcases will now be captured by the <junit> task
  and passed to the formatters.

* Quote the -group parameter to Javadoc as per the specification

* Initialise classes when loaded through the AntClassLoader - that is, run
  static initializers

* Implement getResource() and getResources() in AntClassLoader

* Create the <ejbjar> weblogic command line as a set of arguments rather than
  as a single line. Avoids problems with paths which contain spaces.

* <ejbjar> now fails when the weblogic ejbc compiler reports an error.

* Make the AntClassLoader load resources in the same order as it currently
  loads classes.

* Handle classpaths with spaces

* Make sure XSLT processors close their output files in <style>.

* perform proper uptodate check in <rmic> when compiling for IIOP.

* <jjtree>'s uptodate test works even if outputdirectory is not the
  parent dir of target

* <copy> will remove target file (if it exists) before writing to it -
  this avoids problems with links on filesystems that support them.

* <ftp> now properly recurses remote directories.

* <ftp> closes remote connection when it's done.

* <junit> tries to include all necessary classes for the task itself
  to the classpath when running in fork mode - doesn't work for JDK 1.1

* <apply> and <execon> do now execute the command only once, if you
  specify the parallel attribute - instead of once per fileset.

* directory based tasks and fileset could miss some included files in
  directories that have been excluded

* <fixcrlf> failed for large files.

* <move> removed files you tried to move to themselves.

* <sql> task will not trty to print the result set unless the query succeeded.

* Ant classloader will now ignore paths which are invalid relative to the
  project base

* <ejbjar> weblogic elements check for jar file changes has been fixed.
  Previously some changes would not be included.

* properties loaded from properties files are now resolved internally. This
  removes the spurious warnings about usage of properties which have not been
  set.

* <jar> task and friends now process the JAR manifest to ensure it is valid.

* The task finished event now includes any exception thrown by the task.

* <java> task now supports a jvmVersion attribute so that if another JVM is
  being used, Ant can determine which options to use for features such as the
  VM memory limits


Changes from Ant 1.2 to Ant 1.3
===========================================

Changes that could break older environments:
--------------------------------------------

* Ant doesn't search for the buildfile anymore, unless you use the new
  -find argument.

* <perforce> has been replaced by a number of new tasks.

* <javac> is now implemented using a factory. This makes extending
  javac to use a new compiler a lot easier but may break custom
  versions of this task that rely on the old implementation.

* The output generated by the xml formatter for <junit> has changed a
  little, it doesn't append " sec" in the time attribute anymore.

Other changes:
--------------

* A GUI Frontend: Antidote. This is currently in development. At this
  time, this is not part of the Ant release, although the source is
  included if you are interested.

* New tasks: stylebook, propertyfile, depend, antlr, telnet, csc,
  ilasm, apply, javah, several clearcase tasks, junitreport, sound

* Added output attribute to <java>.

* Added nested zipfileset element to <zip>

* Changed <sql> so that printing is at the task level rather than
  the statement level.

* javadoc task will pass -d flag to any doclet if the destDir attribute is
  given. If the doclet does not accept the -d flag then omit the destdir
  attribute.

* <cab> can work on non-Windows platforms with the help of libcabinet.
  See http://trill.cis.fordham.edu/~barbacha/cabinet_library/.

* <ftp> now supports passive mode.

* New <mapper> data type that can be used to get influence on the
  target files for some tasks like <copy> or enable new types of tasks
  like <apply>.

* <execon> provides more control over the command line now, the names
  of the source files are no longer required to be at the end of the
  command.

* Style tasks will now support TraX compliant XSL processors if one is present
  in your classpath.

* Added a failonerror to the javac task. If set to false, the build will
  continue even if there are compilation errors.

* Added nested format elements to the tstamp task allowing additional time
  formats to be defined for arbitrary properties.

* Added classpath attribute and nested classpath element to <property>
  to make the resource attribute more powerful.

* ${} property expansion will now be performed on the patterns read
  from files specified as includesfile or excludesfile attributes.

* The <tar> and <untar> tasks now support GNU format for handling paths
  which are greater than 100 characters in length. In addition the <tar>
  task now supports nested filesets through which the file permissions
  may be controlled.

* wlrun, wlstop and ejbjar now support Weblogic 6.0

* The MPasre task has been updated to work with MParse 2.0

* The documentation has been significantly updated.


Fixed bugs:
-----------

* <signjar> no longer uses deprecated methods.

* javadoc's failonerror attribute works again

* javadoc's additionalparam attribute will now be split into separate
  parameters (on spaces) to allow for more than one parameter.

* Changed <sql> task so that printing result sets works on Oracle

* Changes to ddcreator and ejbc helper to respect the descriptor hierarchy
  keppgenerated in ejbc can now be turned off

* ejbjar now correctly ignores <ejb-ref> elements in the deployment descriptor.
  CMP files are included by parsing the weblogic deployment descriptor rather
  than relying on the naming convention used in ant 1.2

* ejbjar includes super classes and super interfaces into the generated ejb
  jar files. The <support> nested element allows support classes to be
  included in the EJB jar. The toplink element should now correctly locate
  the toplink descriptor.

* <vssget> now correctly deals with spaces in arguments

* <jar> fails early if a given manifest file doesn't exist

* <rmic> doesn't search for the _Skel file anymore when stubversion is
  set to 1.2.

* <rmic> uses the the same classpath to verify a class can be rmic'd
  as it passes to the compiler.

* org.apache.tools.mail.MailMessage (and therefore <mail>) can now
  handle SMTP servers sending multi line responses.

* nested <classpath> elements of <taskdef> now work for <taskdef>s not
  nested into <target> as well.

* <property> and <available> will search for the resource "foo" instead
  of "/org/apache/tools/ant/taskdefs/foo" when given a relative resource
  name foo.

* Handle build files in directories whose name contained a "#" character

* <junit> can now log to files whose name contains a comma as well.

* The AntClassLoader now refers to the loader which loaded it, any
  requests it does not handle itself. Previously these went to the
  primordial loader.

Changes from Ant 1.1 to Ant 1.2
===============================

Changes that could break older environments:
--------------------------------------------

* Semantics of <property> has changed again in the hope to be more
  intuitive. ${} expansion now happens at runtime and <property> tags
  living inside of targets only take effect if they are visited at
  runtime.

  As a side effect of this change, task's attributes get set at runtime
  not at parser time as well, which might change the results of
  <script>s or other custom tasks that reference other tasks by their id
  attribute.

* copying of support files in <javac> has been removed - as well as
  the filtering attribute.

* the <expand> and <keysubst> tasks have been removed.

* the ignore and items attributes of directory based tasks have been removed.

* the command line switches _not_ starting with - have been removed.

* Path and EnumeratedAttribute have been moved from
  org.apache.tools.ant to org.apache.tools.ant.types.

* the class attributes of <available>, <java>, <rmic> and <taskdef>
  have been removed.

* the src attribute of <chmod> has been removed.

* <patch> and <javadoc> have lost some of their attributes.

* <java> and <cvs> have lost some undocumented attributes.

* the Unix antRun script would search for command.sh in the directory
  it changed to and invoke this instead of command if present. This
  behavior has been dropped.

* <ejbjar> task syntax has been changed significantly

* <exec> is no longer implemented by org.apache.tool.ant.taskdefs.Exec.
  Custom tasks that rely on Project.createTask("exec") to return an
  instance of this class are going to fail.

* nested <include> and <exclude> elements expect the value of their
  name attribute to be a single pattern, they don't accept multiple
  patterns anymore. Split them into multiple elements of the same type.

* <delete dir="somedir" /> will now delete the directory itself as
  well as all included files. If you just want to clean out the
  directory and keep the empty one, use a nested fileset.

Other changes:
--------------

* New tasks: antstructure, cab, execon, fail, ftp, genkey, jlink,
  junit, sql, javacc, jjtree, starteam, war, unwar, uptodate,
  native2ascii, copy, move, mparse.

* copydir, copyfile, deltree and rename are now deprecated. They
  should be replaced with the new copy, delete and move tasks.

* <java> uses a ClassLoader of its own in no-fork mode if a classpath is
  specified.

* <style> will create the necessary target directories and reprocess
  all files if the stylesheet changes.

* New data types fileset and patternset - expected to get a broader use.
  They, as well as PATH like structures, can now be defined on a global
  level and later be referenced by their id attribute.

* You can specify environment variables to <exec>.

* <get> can check whether a remote file is actually newer than a local
  copy before it starts a download (HTTP only).

* Added a -logger option to allow the class which performs logging to be
  specified on the command line.

* Added a -emacs option to tell the logger to leave out taskname adornments
  on log output.

* <chmod> works on all files in parallel and supports multiple filesets.

* <replace> can now use tokens and/or values that cross line boundaries.

* build.compiler supports now jvc as well.

* project specific help can now be obtained with the -projecthelp option.

* Added a -debug option to make -verbose less verbose (and more useful)

* Ant will now search for a file named build.xml in the parent directory
  and above (towards the root of the filesystem) if you didn't specify
  -buildfile and there is no build.xml in the current directory.

* <echo> can now write to a file and accepts nested text.

Fixed bugs:
-----------

* <chmod> didn't work when used as a directory based task.

* Path, Available, Property didn't resolve relative filenames with
  respect to the Project's basedir.

* Project didn't interpret the basedir attribute correctly in all
  cases.

* Nested <src> in <javac> caused NullPointerException.

* Corrupt Zip- and Jar-files ar now deleted if the task fails.

* many more fixes we've forgotten to document here ...

* The packagelistloc attribute of <javadoc>'s <link> child will be
  resolved as a file (i.e. it is either absolute or relative to
  basedir).
