Retry Task

## Retry

### Description

Retry is a container which executes a single nested task until either: there is no failure; or: its retrycount has been exceeded. If this happens a BuildException is thrown. Since Apache Ant 1.7.1

### Parameters

Attribute | Description | Required
retrycount | number of times to attempt to execute the nested task | Yes

Any valid Ant task may be embedded within the retry task.

### Example

    <retry retrycount="3">
      <get src="http://www.unreliable-server.com/unreliable.tar.gz"
           dest="/home/retry/unreliable.tar.gz" />
    </retry>

This example shows how to use `<retry>` to wrap a task which must interact with an unreliable network resource.
