Peter, I found a problem with your solution. My build uses <antcall/> which mens the script will be executed several times.
But you can only run the script once per build process. Otherwise, beanshell fails with: [script] java.lang.reflect.InvocationTargetException: java.lang.LinkageError: trying to redefine class NameSelector (bad class loader?)

I will try to solve my problem by defining different classes each time.
