There might be still a misunderstanding.
I am talking of a small number of two, three or four *.jba projects.
Each of them should be compiled independently.
Afterward, the resulting *.class files are copied together in one central *.jar file.
So, the resulting framework looks like today.
In case of a change in a given class, only the respective *.jba has to be recompiled
and the merge repeated. This should always be faster than a complete recompile of today.
