build: Optimize build procedure.

Each of the interfaces' jars had all three of them included, which
is not ideal, so only include the corresponding interface's classes
on each jar. Furthermore, we don't need debug data appended to each
class, as we already have the source code available with variables,
methods, etc mostly explained.
