Source-only dependencies are not detected

If a class in the `src/main/java` part module A has a source-only dependency on a class in module B, the dependency dependency of A to B is not detected. This can lead to build failures if any class in the `src/main/test` part of module A also has dependencies on module B as the analyzer claims that the dependency of module B should be moved to the `test` scope. Doing so - however - then breaks the build.

One such source-only dependency would be the import of a compile-time constant (e.g. static final String = "XXX") from a class in module B. Such constants are inlined into the class file produced for the class of module A. Thus, the compile-time dependency on module B cannot be determined by inspecting the class file using ASM.
