         Allows plug-ins to define arbitrary Ant tasks for use 
by the Ant infrastructure.  The standard Ant infrastructure 
allows for the addition of arbitrary tasks.  
Unfortunately, it is unlikely that the Ant Core plug-in 
would have the classes required by these tasks on its 
classpath (or that of any of its prerequisites).  
To address this, clients should define an extension 
which plugs into this extension-point and maps a 
task name onto a class.  The Ant plug-in can then 
request that the declaring plug-in load the specified class.

         The following is an example of an Ant tasks extension point: 
&lt;p&gt;
&lt;pre&gt;
   &lt;extension point=&quot;org.eclipse.ant.core.antTasks&quot;&gt;
      &lt;antTask name=&quot;coolTask&quot; class=&quot;com.example.CoolTask&quot; library=&quot;lib/antSupport.jar&quot;/&gt;
   &lt;/extension&gt; 
&lt;/pre&gt;
&lt;/p&gt;
In the above example the &lt;code&gt;antSupport.jar&lt;/code&gt; must be created using an Ant project builder. For more information about creating project builders and how they work, please refer to the following help topics: &lt;b&gt;Contributing tasks and types&lt;/b&gt;, &lt;b&gt;Ant buildfiles as project builders&lt;/b&gt; and &lt;b&gt;Creating a project builder Ant buildfile&lt;/b&gt;
