<h1><call></h1>
<p> Calls a NAnt target in the current project. </p>
<p> When the <a href="../tasks/call.html"><call></a> task is used to execute a target, both that target and all its dependent targets will be re-executed. </p>
<p> To avoid dependent targets from being executed more than once, two options are available: </p>
<ul style="list-style-type: disc;">
<li> Add an "unless" attribute with value "${<a href="../functions/target.has-executed.html">target::has-executed</a>('<code><target name></code>')}" to the dependent targets. </li>
<li> Set the <code>cascade</code> attribute on the <a href="../tasks/call.html"><call></a> task to <b>false</b> (<code>recommended</code>). </li>
</ul>

<h3>Examples</h3>
<ul class="examples">
<li>
<p> Call the target "build". </p>
<pre class="code">
<call target="build" />
</pre>
</li>
<li>
<p> This shows how a project could 'compile' a debug and release build using a common compile target. </p>
<pre class="code">
<project default="build">
<property name="debug" value="false" />
<target name="init">
<echo message="initializing" />
</target>
<target name="compile" depends="init">
<echo message="compiling with debug = ${debug}" />
</target>
<target name="build">
<property name="debug" value="false" />
<call target="compile" />
<property name="debug" value="true" />
<call target="compile" />
</target>
</project>
</pre>
<p> The <code>cascade</code> parameter of the <a href="../tasks/call.html"><call></a> task defaults to <b>true</b>, causing the "init" target to be executed for both the "debug" and "release" build. </p>
<p> This results in the following build log: </p>
<pre class="code">build:
init:
[echo] initializing
compile:
[echo] compiling with debug = false
init:
[echo] initializing
compile:
[echo] compiling with debug = true
BUILD SUCCEEDED
</pre>
<p> If the "init" should only be executed once, set the <code>cascade</code> attribute of the <a href="../tasks/call.html"><call></a> task to <b>false</b>. </p>
<p> The build log would then look like this: </p>
<pre class="code">build:
init:
[echo] initializing
compile:
[echo] compiling with debug = false
compile:
[echo] compiling with debug = true
BUILD SUCCEEDED
</pre>
</li>
</ul>
