How to get ant to not print the BuildException/ExitStatusException stack trace

Question

I have written an ant task (bnd) that needs to indicate failure. The only way to indicate failure that I found is to throw a BuildException/ExitStatusException. However, I do not want a stack trace because it just takes up unnecessary screen space. Any idea how to achieve this?

Check out the tutorial at http://ant.apache.org/manual/tutorial-writing-tasks.html#complex

There they show an example that just fails gracefully, throwing a BuildException in the custom task but not showing the stack trace in the console window.

The code to pay attention to is in the execute() method of the 'HelloWorld' Class, and where the helloworld task is called from the use.fail target.
