<h2><a name="scp">SCP</a></h2>
<h3>Description</h3>
<p><em>since Ant 1.6</em></p>
<p>Copies a file or FileSet to or from a remote machine running SSH daemon.
FileSet <i>only</i> works for copying files from the local machine to a
remote machine.</p>
<p><b>Note:</b> This task depends on external libraries not included
in the Ant distribution. See <a
href="../install.html#librarydependencies">Library Dependencies</a>
for more information. This task has been tested with jsch-0.1.2 and jsch-0.1.3.</p>

<h3>Parameters specified as nested elements</h3>
<h4>fileset</h4>
<p><a href="../CoreTypes/fileset.html">FileSet</a>s are used to select
sets of files to copy.
To use a fileset, the <code>todir</code> attribute must be set.</p>
<h3>Examples</h3>
<p><b>Copy a single local file to a remote machine</b></p>
<pre>
<scp file="myfile.txt" todir="user:password@somehost:/home/chuck"/>
</pre>
<p><b>Copy a single local file to a remote machine with separate
password attribute</b></p>
<pre>
<scp file="myfile.txt" todir="user@somehost:/home/chuck" password="password"/>
</pre>
<p><b>Copy a single local file to a remote machine using key base
authentication.</b></p>
<pre>
<scp file="myfile.txt"
todir="user@somehost:/home/chuck"
keyfile="${user.home}/.ssh/id_dsa"
passphrase="my extremely secret passphrase"
/>
</pre>
<p><b>Copy a single remote file to a local directory</b></p>
<pre>
<scp file="user:password@somehost:/home/chuck/myfile.txt" todir="../some/other/dir"/>
</pre>
<p><b>Copy a remote directory to a local directory</b></p>
<pre>
<scp file="user:password@somehost:/home/chuck/*" todir="/home/sara" />
</pre>
<p><b>Copy a local directory to a remote directory</b></p>
<pre>
<scp todir="user:password@somehost:/home/chuck/">
<fileset dir="src_dir"/>
</scp>
</pre>
<p><b>Copy a set of files to a directory</b></p>
<pre>
<scp todir="user:password@somehost:/home/chuck">
<fileset dir="src_dir">
<include name="**/*.java"/>
</fileset>
</scp>
<scp todir="user:password@somehost:/home/chuck">
<fileset dir="src_dir" excludes="**/*.java"/>
</scp>
</pre>
<p><strong>Security Note:</strong> Hard coding passwords and/or usernames
in scp task can be a serious security hole. Consider using variable
substituion and include the password on the command line. For example:<br>
<pre>
<scp todir="${username}:${password}@host:/dir" ...>
</pre>
Invoke ant with the following command line:
<pre>
ant -Dusername=me -Dpassword=mypassword target1 target2
</pre>
</p>
<p><strong>Unix Note:</strong> File permissions are not retained when files
are copied; they end up with the default <code>UMASK</code> permissions
instead. This is caused by the lack of any means to query or set file
permissions in the current Java runtimes. If you need a permission-
preserving copy function, use <code><exec executable="scp" ... ></code>
instead.
