[X] Pick one library and one or two clients: Working with commons-cli and a couple of clients
[X] Manually debloat with JDbl and Proguard: Debloat successfully with JDbl, not possible to debloat with Proguard since it requires an entry-point and the library doesn't provide one.
[X] Run the build of the clients with the versions of the library: The build passes, but it seems to be because of the clients only use a small part of the library in the tests (or not use it at all).
