I use CMake for building a multi-platform multi-language project where
for most parts it fits very well.  However, one part of the project is
written in Java, with some native implementations.  So it would be great
to have a nice Java support in CMake.  Using another build system just
for that part adds one to many build-time dependency.

The pitfalls I've encountered in CMake Java support were:

    * All objects are always rebuilt.
    * The generated JAR file is polluted with build system CMake files.

This is why I would like to contribute to the great CMake project and
have a nice simple Java support.
