| <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><retry></code> to wrap a task which must interact with |
| an unreliable network resource.</p> |
