The problem is that the copy-maven-plugin is incompatible with Maven 3.1. If you use Maven 3.0.x you should not see the problem.

[gmaney]

same result with

Apache Maven 3.2.1 (ea8b2b07643dbb1b84b6d16e1f08391b666bc1e9;

Hello.
We have two PC with maven 3.3 version and the same project with dependecy from the subject.
And surpise: one pc compiles project and another does not want to do it because of the error above.
We have only different java versions for maven (1.7 vs my 1.8).
Who can tell how it could be?
My maven is
$ mvn --version
Apache Maven 3.3.3 (7994120775791599e205a5524ec3e0dfe41d4a06; 2015-04-22T14:57:37+03:00)
Maven home: C:\Program Files\apache-maven-3.3.3
Java version: 1.8.0_45, vendor: Oracle Corporation
