<h2>Retry</h2>
<h3>Description</h3>
<p>Retry is a container which executes a single nested task until either: there is no failure; or:
its <em>retrycount</em> has been exceeded. If this happens a BuildException is thrown.
<em>Since Ant 1.7.1</em></p>

<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">retrycount</td>
    <td valign="top">number of times to attempt to execute the nested task</td>
    <td valign="top" align="center">Yes</td>
  </tr>
</table>
<p>Any valid Ant task may be embedded within the retry task.</p>

<h3>Example</h3>
<pre>
&lt;retry retrycount="3"&gt;
  &lt;get src="http://www.unreliable-server.com/unreliable.tar.gz" 
       dest="/home/retry/unreliable.tar.gz" /&gt;
&lt;/retry&gt;
</pre>
<p>This example shows how to use <code>&lt;retry&gt;</code> to wrap a task which must interact with an unreliable network resource.</p>
