<body>

<h2><a name="echo">Do</a></h2>
<h3>Description</h3>
<p>
This task is similar to the
<a href="antcall.html"><code>&lt;antcall&gt;</code></a>
task; however, <code>&lt;do&gt;</code> will not
re-run common dependencies. Using
<code>&lt;antcall&gt;</code> to run several targets that all have
the same dependency(s) will cause the dependent
target(s) for each called target to be run again.
This results in common targets, such as &quot;init&quot;-type targets,
being run many times.  Using <code>&lt;do&gt;</code>
instead of <code>&lt;antcall&gt;</code> prevents any common dependencies
from being run more than once.
</p>
<p>
<strong>Note:</strong> The <code>&lt;do&gt;</code> task will still re-run
any dependent target that was run prior to the <code>&lt;do&gt;</code> task(s)
being run.

<h3>Parameters</h3>
<table border="1" cellpadding="2" cellspacing="0">
  <tr>
    <td valign="top"><b>Attribute</b></td>
    <td valign="top"><b>Description</b></td>
    <td align="center" valign="top"><b>Required</b></td>
  </tr>
  <tr>
    <td valign="top">target</td>
    <td valign="top">The target to run.</td>
    <td valign="top" align="center">Yes</td>
  </tr>
</table>

<h3>Examples</h3>

<pre>
  &lt;target name=&quot;all&quot;&gt;
    &lt;do target=&quot;target1&quot;/&gt;
    &lt;do target=&quot;target2&quot;/&gt;
  &lt;/target&gt;
</pre>

will run the targets <code>target1</code> and <code>target2</code>.
If both <code>target1</code> and <code>target2</code> depend on,
for example, the <code>init</code> target, it will only be run once
rather than once for <code>target1</code> and again for <code>target2</code>.
