      Description

      The execution of the copy-dependencies goal fails if the classifier "sources" is selected the mojo fails with a NullPointerException.

      Somehow i can work around the bug by removing the classifier afterwards: <stripClassifier>true</stripClassifier>.
      But then the <overwriteIfNewer> flag is ignored. which results in lot's of unwanted file copy changes during my builds.
