Execute a default task in ANT in case of failure

Hi, I'm currently using ANT for building my Java project on a Windows XP machine. In my build.xml file I've defined 3 task and I would like that,in case of fail,a default task be executed before closing the building and exiting (like a recovery procedure). I would like to know if it's possible.

thanks

Googled and found this. It's basically a try/catch for Ant. Might be worth a look: http://ant-contrib.sourceforge.net/tasks/tasks/trycatch.html

Thanks for you answer..it looks what I'm looking for but I cannot install ant-contrib. I'm just using the standard ANT

Never heard of such a property/task, but the follwing just comes to my mind: you could use an additional 'Master' ant script.

The master script (a new one) includes all public targets from the original one and delegates the work to the corresponding task in your build script (ant calls)
If the delegate fails, the master should be able to recognize the failure and could call the 'clean-up' task (either on the 'master' or on the original build file)

thanks for your answer. The point is that if I'm able to recognize the failure of the sub-script in the master-script, should not I be able to do it directly with a task in the master?

If you can catch the failure of a task, then you can call another target. But if the ant script stopps because a target fails, then I doubt that you can catch this failure in the same ant script to call another target. (but now I see, you talked about failing tasks, not targets)
