access to task description?

["Hertel, Oliver" <Ol...@Dresdner-Bank.com>]

Hello,

is there a way to access the target description, maybe like this?

  <target name="build" description="Compiles main classes"
          depends="prepare">
    <echo message="${description}" />
  ...
  </target>

Thanks in advance.

Just thinking, perhaps a Document Object Model would be nice for Ant :-) Then 
you could have properties like:

   ant.project --> The current project
   ant.project.name --> The name of the current project
   ant.project.tasks --> All tasks in the current project
   ant.currenttask --> The current task
   ant.currenttask.name --> The name of the current task
   ant.currenttask.description --> The description of the current task
   :

This would be similar to the approach used in HTML (JavaScript/VBscript)
Some of these properties are currently already available as 'magic 
properties'.

You can either add the following to every target you want to have the
description printed out for:
    <script language="javascript"><![CDATA[
      desc = self.getOwningTarget().getDescription();
      if( desc != null ) {
        java.lang.System.out.println(desc);
      }
    ]]></script>

Or compile, jar, and taskdef the following:
  import org.apache.tools.ant.BuildException;
  import org.apache.tools.ant.Task;

  public class PrintDesc extends Task {

      // The method executing the task
      // @param None Executes the task
      public void execute() throws BuildException {
          String desc = getOwningTarget().getDescription();
          if( desc != null ) {
              System.out.println(desc);
          }
      }
  }

and include a <printdesc/> in any target you want the description printed
out for.

(Maybe there's some more clever way, but it's the best I can come up with
while waiting for my coffee to brew :)
