Description

On my machine with mvn 3.0.2, I get a ClassCastException trying to use the maven protoc plugin. The issue seems to be that mvn 3.0.2 sees the List<File> parameter, and doesn't see the generic type argument, and stuffs Strings inside instead. So, we get ClassCastException trying to use the objects as Files.
