<h2><a name="ftp">FTP</a></h2>
<h3>Description</h3>
<p>The ftp task implements a basic FTP client that can send, receive,
list, delete files, and create directories.  See below for descriptions and examples of how
to perform each task.</p>
<p><b>Note:</b> This task depends on external libraries not included in the Ant distribution.
See <a href="../install.html#commons-net">Library Dependencies</a> for more information.</p>
<p>The ftp task attempts to determine what file system is in place on the FTP server.
Supported server types are Unix, NT, OS2, VMS, and OS400.  In addition, NT and OS400 servers
which have been configured to display the directory in Unix style are also supported correctly.
Otherwise, the system will default to Unix standards.
<i>remotedir</i> must be specified in the exact syntax required by the ftp
server. If the usual Unix conventions are not supported by the server,
<i>separator</i> can be used to set the file separator that should be used
instead.</p>
<p>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 does not currently use the proxy information set by the
<a href="setproxy.html">&lt;setproxy&gt;</a> task, and cannot go through
a firewall via socks. 
<p>
<b>Warning: </b> there have been problems reported concerning the ftp get with newer attribute.
Problems might be due to format of ls -l differing from what is expected by commons-net,
for instance due to specificities of langage used by the ftp server in the directory listing.
If you encounter such a problem, please send an email including a sample directory listing
coming from your ftp server (ls -l on the ftp prompt).

</table><h3>Parameters specified as nested elements</h3>
<h4>fileset</h4>
<p>The ftp task supports any number of nested <a
href="../CoreTypes/fileset.html"><code>&lt;fileset&gt;</code></a> elements to specify
the files to be retrieved, or deleted, or listed, or whose mode you want to change.</p>
<p>
The attribute <code>followsymlinks</code> of <code>fileset</code> is fully supported on
local (put) as well as remote (get, chmod, delete) filesets.
<em>Before ant 1.6 there was no support of symbolic links in remote filesets.
In order to exclude symbolic links (preserve the behavior of ant 1.5.x and older),
you need to explicitly set <code>followsymlinks</code> to <code>false</code>.</em>
</p>
<p>
Remote filesets do not support selectors.<br/>
</p>

<h3>Sending Files</h3>
<p>The easiest way to describe how to send files is with a couple of examples:</p>
<pre>
  &lt;ftp server=&quot;ftp.apache.org&quot;
       userid=&quot;anonymous&quot;
       password=&quot;me@myorg.com&quot;&gt;
    &lt;fileset dir=&quot;htdocs/manual&quot;/&gt;
  &lt;/ftp&gt;
</pre>
<p>Logs in to <code>ftp.apache.org</code> as <code>anonymous</code> and 
uploads all files in the <code>htdocs/manual</code> directory 
to the default directory for that user.</p>
<pre>  &lt;ftp server=&quot;ftp.apache.org&quot;
       remotedir=&quot;incoming&quot;
       userid=&quot;anonymous&quot;
       password=&quot;me@myorg.com&quot;
       depends=&quot;yes&quot;
  &gt;
    &lt;fileset dir=&quot;htdocs/manual&quot;/&gt;
  &lt;/ftp&gt;</pre>
<p>Logs in to <code>ftp.apache.org</code> as <code>anonymous</code> and 
uploads all new or changed files in the <code>htdocs/manual</code> directory 
to the <code>incoming</code> directory relative to the default directory
for <code>anonymous</code>.</p>
<pre>  &lt;ftp server=&quot;ftp.apache.org&quot;
       port=&quot;2121&quot;
       remotedir=&quot;/pub/incoming&quot;
       userid=&quot;coder&quot;
       password=&quot;java1&quot;
       depends=&quot;yes&quot;
       binary=&quot;no&quot;
  &gt;
    &lt;fileset dir=&quot;htdocs/manual&quot;&gt;
      &lt;include name=&quot;**/*.html&quot;/&gt;
    &lt;/fileset&gt;
  &lt;/ftp&gt;</pre>
<p>Logs in to <code>ftp.apache.org</code> at port <code>2121</code> as 
<code>coder</code> with password <code>java1</code> and uploads all new or 
changed HTML files in the <code>htdocs/manual</code> directory to the 
<code>/pub/incoming</code> directory. The files are transferred in text mode. Passive mode has been switched on to send files from behind a firewall.</p>
<pre>  &lt;ftp server=&quot;ftp.nt.org&quot;
       remotedir=&quot;c:\uploads&quot;
       userid=&quot;coder&quot;
       password=&quot;java1&quot;
       separator=&quot;\&quot;
       verbose=&quot;yes&quot;</pre>
<PRE>
  &gt;
    &lt;fileset dir=&quot;htdocs/manual&quot;&gt;
      &lt;include name=&quot;**/*.html&quot;/&gt;
    &lt;/fileset&gt;
  &lt;/ftp&gt;</PRE><p>Logs in to the Windows-based <code>ftp.nt.org</code> as 
<code>coder</code> with password <code>java1</code> and uploads all 
HTML files in the <code>htdocs/manual</code> directory to the 
<code>c:\uploads</code> directory.  Progress messages are displayed as each
file is uploaded.</p>
<h3>Getting Files</h3>
<p>Getting files from an FTP server works pretty much the same way as 
sending them does.  The only difference is that the nested filesets
use the remotedir attribute as the base directory for the files on the
FTP server, and the dir attribute as the local directory to put the files
into.  The file structure from the FTP site is preserved on the local machine.</p>
<pre>
  &lt;ftp action=&quot;get&quot;
       server=&quot;ftp.apache.org&quot;
       userid=&quot;anonymous&quot;
       password=&quot;me@myorg.com&quot;&gt;
    &lt;fileset dir=&quot;htdocs/manual&quot;&gt;
      &lt;include name=&quot;**/*.html&quot;/&gt;
    &lt;/fileset&gt;
  &lt;/ftp&gt;
</pre>
<p>Logs in to <code>ftp.apache.org</code> as <code>anonymous</code> and 
recursively downloads all .html files from default directory for that user 
into the <code>htdocs/manual</code> directory on the local machine.</p>
. 
<h3>Deleting Files</h3>
As you've probably guessed by now, you use nested fileset elements to 
select the files to delete from the remote FTP server.  Again, the 
filesets are relative to the remote directory, not a local directory.  In
fact, the dir attribute of the fileset is ignored completely.

<pre>
  &lt;ftp action=&quot;del&quot;
       server=&quot;ftp.apache.org&quot;
       userid=&quot;anonymous&quot;
       password=&quot;me@myorg.com&quot;&gt;
    &lt;fileset&gt;
      &lt;include name=&quot;**/*.tmp&quot;/&gt;
    &lt;/fileset&gt;
  &lt;/ftp&gt;
</pre>
<p>Logs in to <code>ftp.apache.org</code> as <code>anonymous</code> and
tries to delete all *.tmp files from the default directory for that user.
If you don't have permission to delete a file, a BuildException is thrown.</p>
<h3>Listing Files</h3>
<pre>
  &lt;ftp action=&quot;list&quot;
       server=&quot;ftp.apache.org&quot;
       userid=&quot;anonymous&quot;
       password=&quot;me@myorg.com&quot; 
       listing=&quot;data/ftp.listing&quot;&gt;
    &lt;fileset&gt;
      &lt;include name=&quot;**&quot;/&gt;
    &lt;/fileset&gt;
  &lt;/ftp&gt;
</pre>
<p>This provides a file listing in <code>data/ftp.listing</code> of all the files on
the FTP server relative to the default directory of the <code>anonymous</code>
user. The listing is in whatever format the FTP server normally lists files.</p>

<h3>Creating Directories</h3>
<p>Note that with the mkdir action, the directory to create is specified using the
remotedir attribute.</p>
<pre>
  &lt;ftp action=&quot;mkdir&quot;
       server=&quot;ftp.apache.org&quot;
       userid=&quot;anonymous&quot;
       password=&quot;me@myorg.com&quot; 
       remotedir=&quot;some/remote/dir&quot;/&gt;
</pre>
<p>This creates the directory <code>some/remote/dir</code> beneath the default root
directory.  As with all other actions, the directory separator character must be correct
according to the desires of the FTP server.</p>
<h3>Removing Directories</h3>
This action uses nested fileset elements to 
select the directories to remove from the remote FTP server.  The 
filesets are relative to the remote directory, not a local directory. 
The dir attribute of the fileset is ignored completely.
The directories to be removed must be empty, or contain only
other directories that have been also selected to be removed by the filesets
patterns, otherwise a BuildException will be thrown.
Also, if you don't have permission to remove a directory, a BuildException is 
thrown.

<pre>
  &lt;ftp action=&quot;rmdir&quot;
       server=&quot;ftp.apache.org&quot;
       userid=&quot;anonymous&quot;
       password=&quot;me@myorg.com&quot; 
       remotedir=&quot;/somedir&quot; &gt;
    &lt;fileset&gt;
      &lt;include name=&quot;dira&quot;/&gt;
      &lt;include name=&quot;dirb/**&quot;/&gt;
    &lt;/fileset&gt;
  &lt;/ftp&gt;
</pre>
<p>Logs in to <code>ftp.apache.org</code> as <code>anonymous</code> and
tries to remove <code>/somedir/dira</code> directory and
all the directories tree starting at, and including, <code>/somedir/dirb</code>.
When removing the <code>/somedir/dirb</code> tree,
it will start at the leaves moving up to the root, so that when
it tries to remove a directory it is sure all the directories under it are
already removed.
Obviuosly all the files in the tree must have been already deleted.
</p>
<p>As an example suppose you want to delete everything contained into 
<code>/somedir</code>, so invoke first the <code>&lt;ftp&gt;</code> task with
<code>action=&quot;delete&quot;</code>, then with 
<code>action=&quot;rmdir&quot;</code> specifying in both cases
<code>remotedir=&quot;/somedir&quot;</code> and

<pre>
    &lt;fileset&gt;
        &lt;include name=&quot;**&quot;/&gt;
    &lt;/fileset&gt;
</pre>

The directory specified in the <code>remotedir</code> parameter is never
selected for remove, so if you need to remove it, specify its parent in
<code>remotedir</code> parameter and include it in the 
<code>&lt;fileset&gt;</code> pattern, like <code>&quot;somedir/**&quot;</code>.
