    Normally has conceptually-related sources; invoking the ``compile`` goal
    on this target compiles Java and generates classes. Invoking the ``jar``
    goal on this target creates a ``.jar``; but that's an unusual thing to do.
    Instead, a ``jvm_binary`` might depend on this library; that binary is a
    more sensible thing to bundle.
