maven-dependency-plugin: copy goal with overwrite=false doesn't copy

[Kevin Stembridge]

Hi folks,
There seems to be a problem with the maven-dependency-plugin copy goal
when overwrite is set to false. It says that the dependency already
exists and doesn't copy it in.

This pom is from a bare-bones project that shows my problem.
