Checking if a Target Exists

[Steve Amerige]

Hi all,

I want to be able to check if a target exists and hope you can help.  I'm looking for a generic solution that doesn't rely any 
knowledge of the target name to be checked.  It is not possible to modify the target code.  And, I'd like to avoid any solutions 
that cause the entire JVM to be loaded (e.g., as with antcall).

My environment is Ant 1.7 and allows for the use of Ant-Contrib and Groovy.

Any ideas on how to do this?  Even better, any solutions anyone have to share?!

Thanks,
