------------------------------------------------------------------
I have taken [your
example|https://github.com/khmarbaise/mdep/tree/master/mdep-448] and can
reproduce your problem. I have made a fix for this problem in
[r1622859|http://svn.apache.org/r1622859].
Is it possible that you can check via a 2.9-SNAPSHOT of the
maven-dependency-plugin. I have provided a SNAPSHOT version containing the fix.
It would be nice if you can give feedback if successful or not.

> 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.
