[MSHARED-1212] Detection that class is required in compile scope not happening because class only used as generic type

[jira-importer]

Richard Eckart de Castilho opened MSHARED-1212 and commented

Let's say we have a class in module A which calls a method List<MyObject> getList() from module B. The class MyObject comes from module C.

Also, there is some test class in module A which uses MyObject.

Eclipse will fail to compile this unless MyObject is in the compile scope.

The dependency analyzer will, however, not detect that MyObject is required in the compile scope because the class file for A does not contain a reference to MyObject (due to generic type erasure) and will indicate that module C/MyObject should be in scope test.

It can be difficult to implemented, bytecode may not contain generic types due to Type Erasure
