Update to upstream version 2.7.1
Fixed in plexus-io-2.7.1-1
I believe that this feature is included in plexus-io-2.7.1-1, which is available in Fedora Rawhide, so I am closing this bug now. The build which includes the feature can be found at Koji: http://koji.fedoraproject.org/koji/buildinfo?buildID=756170
