Hi Andreas,
I'm a dyed-in-the-wool Java developer (and also Fedora user) so it makes 
me very happy to know that someone are working to integrate Java in 
CMake. My question is: shouldn't Ant be enough? Or better, Could 
invoking an Ant file as pre/post build command in CMakeLists always 
accomplish any kind of build requirement?
