Catch Ant Task Failure

Does anyone know of a way to catch a failure in an ant task and then execute another based on that failure.

I want to mail certian users if the any part of the building process fails. possiably passing some information regarding the failure.

I'm using Ant 1.6.0

Thanks

Afraid not. But it's probably not an uncommon idea, so maybe you can find a condition for the <condition> tag that is true if the contained instructions fail/succeed. Somewhere on the web...
