> 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.
