<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 valign="top">number of times to attempt to execute the nested task</td>
|

<td valign="top" align="center">Yes</td>

|
|
<p>Any valid Ant task may be embedded within the retry task.</p>

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