<h2 id="cvs">Cvs</h2>
<h3>Description</h3>
<p>Handles packages/modules retrieved from a <a href="https://www.nongnu.org/cvs/"
target="_top">CVS</a> repository.</p>
<p><strong>Important:</strong> This task needs <code>cvs</code> binary 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.  Also note that this task assumes that the cvs executable is compatible with the Unix
version, this is not completely true for certain other CVS clients&mdash;like CVSNT for
example&mdash;and some operation may fail when using such an incompatible client.</p>

<p><strong>CVSNT Note</strong>: CVSNT prefers users to store the passwords inside the registry.  If
the <a href="cvspass.html">cvspass task</a> and the <var>passfile</var> attribute don't seem to work
for you, the most likely reason is that CVSNT ignores your <samp>.cvspass</samp> file completely.
See <a href="https://issues.apache.org/bugzilla/show_bug.cgi?id=21657#c5">bugzilla report 21657</a>
for recommended workarounds.</p>

<h3>Parameters</h3>
<table class="attr">
  <tr>
    <th>Attribute</th>
    <th>Description</th>
    <th>Required</th>
  </tr>
  <tr>
    <td>command</td>
    <td>the CVS command to execute.</td>

  <tr>
    <td>compressionlevel</td>
    <td>A number between <q>1</q> and <q>9</q> (corresponding to possible values for

<h3>Parameters specified as nested elements</h3>

<h4>module</h4>

<p>Specifies a package/module to work on, unlike the package attribute modules specified using this
attribute can contain spaces in their name.</p>

<table class="attr">
  <tr>
    <th>Attribute</th>
    <th>Description</th>
    <th>Required</th>
  </tr>
  <tr>
    <td>name</td>
    <td>The module's/package's name.</td>
    <td>Yes</td>
  </tr>
</table>

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

<pre>&lt;cvs dest=&quot;${ws.dir}&quot; command=&quot;update&quot;/&gt;</pre>
<p>updates the package/module that has previously been checked out into <samp>${ws.dir}</samp>.</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 <samp>patch.txt</samp> which contains a unified
(<code>-u</code>) diff which includes new files added via <code>cvs add</code> (<code>-N</code>) and
can be used as input to <code>patch</code>.  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>
<p>or:</p>
<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 <code>&lt;commandline&gt;</code> elements as you like.  Each will inherit
the <var>failonerror</var>, <var>compression</var>, 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 <code>cvs</code> &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://cvsbook.red-bean.com/cvsbook.html" target="_top">the CVS
book</a> for details, specifically
the <a href="http://cvsbook.red-bean.com/cvsbook.html#Commands%20And%20Options" target="_top">Guide
to CVS commands</a></p>
