<h2><a name="cvs">Cvs</a></h2>
<h3>Description</h3>
<p>Handles packages/modules retrieved from a
<a href="http://www.cvshome.org/" target="_top">CVS</a> repository.</p>
<p>When doing automated builds, the <a href="get.html">get task</a> should be
preferred over the <i>checkout</i> command, because of speed.</p>
<p><b>Important:</b> This task needs &quot;<code>cvs</code>&quot; on the path. If it isn't, you will get
an error (such as error <code>2</code> on windows). If <code>&lt;cvs&gt;</code> doesn't work, try to execute <code>cvs.exe</code>
from the command line in the target directory in which you are working.

<h3>Examples</h3>
<pre>  &lt;cvs cvsRoot=&quot;:pserver:anoncvs@cvs.apache.org:/home/cvspublic&quot;
       package=&quot;ant&quot;
       dest=&quot;${ws.dir}&quot;
  /&gt;</pre>
<p>checks out the package/module &quot;ant&quot; from the CVS
repository pointed to by the <code>cvsRoot</code> attribute, and stores the files in &quot;<code>${ws.dir}</code>&quot;.</p>
<pre>  &lt;cvs dest=&quot;${ws.dir}&quot; command=&quot;update&quot;/&gt;</pre>
<p>updates the package/module that has previously been checked out into
&quot;<code>${ws.dir}</code>&quot;.</p>

<pre>  &lt;cvs command=&quot;-q diff -u -N&quot; output=&quot;patch.txt&quot;/&gt;</pre>

<p>silently (<code>-q</code>) creates a file called <code>patch.txt</code> which contains a unified (<code>-u</code>) diff which includes new files added via &quot;cvs add&quot; (<code>-N</code>) and can be used as input to patch.
The equivalent, using  <code>&lt;commandline&gt;</code> elements, is:
</p>
<pre>
&lt;cvs output=&quot;patch&quot;&gt;
    &lt;commandline&gt;
        &lt;argument value=&quot;-q&quot;/&gt;
        &lt;argument value=&quot;diff&quot;/&gt;
        &lt;argument value=&quot;-u&quot;/&gt;
        &lt;argument value=&quot;-N&quot;/&gt;
    &lt;/commandline&gt;
&lt;/cvs&gt;
</pre>
or:
<pre>
&lt;cvs output=&quot;patch&quot;&gt;
    &lt;commandline&gt;
        &lt;argument line=&quot;-q diff -u -N&quot;/&gt;
    &lt;/commandline&gt;
&lt;/cvs&gt;
</pre>
<p>
You may include as many &lt;commandline&gt; elements as you like. 
Each will inherit the <code>failonerror</code>, <code>compression</code>, and other &quot;global&quot; parameters
from the <code>&lt;cvs&gt;</code> element.
</p>


<pre>  &lt;cvs command=&quot;update -A -d&quot;/&gt;</pre>
<p>Updates from the head of repository ignoring sticky bits (<code>-A</code>) and creating any new directories as necessary (<code>-d</code>).</p>
<p>Note: the text of the command is passed to cvs &quot;as-is&quot; so any cvs options should appear
before the command, and any command options should appear after the command as in the diff example
above. See <a href="http://www.cvshome.org/docs/manual/cvs-1.11.7/cvs.html" target="_top">the cvs manual</a> for details,
specifically the <a href="http://www.cvshome.org/docs/manual/cvs-1.11.7/cvs_16.html" target="_top">Guide to CVS commands</a></p>
