<h2 id="netrexxc">NetRexxC</h2>
<h3>Description</h3>
<p>Compiles a <a href="http://www2.hursley.ibm.com/netrexx" target="_top">NetRexx</a>
source tree within the running (Apache Ant) VM.</p>
<p>The source and destination directory will be recursively scanned for
NetRexx source files to compile.  Only NetRexx files that have no corresponding
class file or where the class file is older than the java file will be compiled.</p>
<p>Files in the source tree are copied to the destination directory,
allowing support files to be located properly in the classpath. The source
files are copied because the NetRexx compiler cannot produce class files in a
specific directory via parameters</p>
<p>The directory structure of the source tree should follow the package
hierarchy.</p>
<p>It is possible to refine the set of files that are being compiled/copied.
This can be done with the <i>includes</i>, <i>includesfile</i>, <i>excludes</i>, <i>excludesfile</i> and
<i>defaultexcludes</i> attributes. With the <i>includes</i> or <i>includesfile</i> attribute you
specify the files you want to have included by using patterns. The
<i>exclude</i> or <i>excludesfile</i> attribute is used to specify the files you want to have
excluded.  This is also done with patterns.  And finally with the
<i>defaultexcludes</i> attribute, you can specify whether you
want to use default exclusions or not. See the section on <a
href="../dirtasks.html#directorybasedtasks">directory based tasks</a>, on how the
inclusion/exclusion of files works, and how to write patterns.</p>
<p>This task forms an implicit <a href="../Types/fileset.html">FileSet</a> and
supports most attributes of <code>&lt;fileset&gt;</code>
(<code>dir</code> becomes <code>srcdir</code>) as well as the nested
<code>&lt;include&gt;</code>, <code>&lt;exclude&gt;</code> and
<code>&lt;patternset&gt;</code> elements.</p>
<p>All properties except classpath, srcdir and destDir are also available as properties in the form
<code>ant.netrexxc.<i>attributename</i></code>, eg.<br>
<code>&lt;property name="ant.netrexxc.verbose" value="noverbose"/&gt;</code><br>
or from the command line as<br>
<code>ant -Dant.netrexxc.verbose=noverbose ...</code>
</p>
<p><strong>Note</strong>: This task depends on external libraries not
included in the Apache Ant distribution. See <a href="../install.html#librarydependencies">Library Dependencies</a>
for more information.</p>
