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

<h3>Parameters</h3>
<table class="attr">
  <tr>
    <th scope="col">Attribute</th>
    <th scope="col">Description</th>
    <th scope="col">Required</th>
  </tr>
  <tr>
    <td>retrycount</td>
    <td>number of times to attempt to execute the nested task</td>
    <td>Yes</td>
  </tr>
  <tr>
    <td>retrydelay</td>
    <td>number of milliseconds to wait between retry attempts task. <em>Since Apache Ant
    1.8.3</em></td>
    <td>No; defaults to no delay</td>
  </tr>
</table>
<p>Any valid Ant task may be embedded within the retry task.</p>

<h3>Example</h3>
<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>
