| 4 | This is the simplest and possibly the most obvious of the "call" type of tasks. It simply calls a target in the current build file and provides exactly the functionality expected by many users of "antcall".
|

| 5 | </p><p>
|
|---|
| 6 | To use this task in your build files, include a task definition like this:
|
|---|
| 7 | </p><pre class="programlisting">
|
|---|
| 8 |
|
|---|
| 9 | <taskdef name="call" classname="ise.antelope.tasks.Call"/>
|
|---|
| 10 |
|
|---|
| 11 | </pre><p>
|
|---|
| 12 | </p><p>
|
|---|
| 13 | There is only one attribute, that is the name of the target to call.
|
|---|
| 14 |
|
|---|
| 15 | </p><div class="table"><a name="id2524808"></a><p class="title"><b>Table 21.1. Call Task Attributes</b></p><table summary="Call Task Attributes" border="1"><colgroup><col><col><col><col></colgroup><thead><tr><th>Attribute</th><th>Description</th><th>Default</th><th>Required</th></tr></thead><tbody><tr><td>target</td><td>The name of a target to execute.</td><td>None</td><td>Yes</td></tr></tbody></table></div><p>

| 17 | There is none of the weird property manipulation done by "ant", "antcall", "antfetch", or "antcallback", and none of the overhead. When you call a target, any properties set in that target are immediately available in the calling target. A simple example should be all that is necessary:
|
|---|
| 18 | </p><pre class="programlisting">
|
|---|
| 19 |
|
|---|
| 20 | <target name="test" description="Test Call">
|
|---|
| 21 | <call target="called"/>
|
|---|
| 22 | <echo>a = ${a}</echo>
|
|---|
| 23 | <echo>b = ${b}</echo>
|
|---|
| 24 | </target>
|
|---|
| 25 |
|
|---|
| 26 | <target name="called">
|
|---|
| 27 | <property name="a" value="A"/>
|
|---|
| 28 | <property name="b" value="B"/>
|
|---|
| 29 | </target>
|
|---|
| 30 |
|
|---|
| 31 | </pre><p>
|
|---|
| 32 | </p></div><div class="navfooter"><hr><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="bk03ch20.html">Prev</a> </td><td width="20%" align="center"><a accesskey="u" href="bk03.html">Up</a></td><td width="40%" align="right"> <a accesskey="n" href="bk03ch22.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">Chapter 20.
