| <h2><a name="echo">Do</a></h2> |
| <h3>Description</h3> |
| <p> |
| This task is similar to the |
| <a href="antcall.html"><code><antcall></code></a> |
| task; however, <code><do></code> will not |
| re-run common dependencies. Using |
| <code><antcall></code> to run several targets that all have |
| the same dependency(s) will cause the dependent |
| target(s) for each called target to be run again. |
| This results in common targets, such as "init"-type targets, |
| being run many times. Using <code><do></code> |
| instead of <code><antcall></code> prevents any common dependencies |
| from being run more than once. |
| </p> |
| <p> |
| <strong>Note:</strong> The <code><do></code> task will still re-run |
| any dependent target that was run prior to the <code><do></code> task(s) |
| being run. |

| <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">target</td> |
| <td valign="top">The target to run.</td> |
| <td valign="top" align="center">Yes</td> |
| </tr> |
| </table> |
| |
| <h3>Examples</h3> |
| |
| <pre> |
| <target name="all"> |
| <do target="target1"/> |
| <do target="target2"/> |
| </target> |
| </pre> |
| |
| will run the targets <code>target1</code> and <code>target2</code>. |
| If both <code>target1</code> and <code>target2</code> depend on, |
| for example, the <code>init</code> target, it will only be run once |
| rather than once for <code>target1</code> and again for <code>target2</code>. |
