Bug 17618 Changing output location should delete all derived resources
F1 1) create a project (autobuild on) 2) import Java sources and resources 3) change output folder to project/bin ->all class files are removed (fine) 4) change output folder back to be the project -> all class files are removed (fine) 5) open project/bin -> all resources are still there Note: When opening the properties dialog on such a resource it is tagged as "Derived". Thus, it should be possible to remove all derived resources as long as they have been created by the Java builder.
