Resolves issue with maven >= 3.1.x

The problem is caused by the plugin using an old version of a  dependency
which I've overriden in our POM. This will now work with maven 3.1.x and 3.2.x.

Also submitting a PR to the plugin repo to bump the dependency version.

Fixes #83
Merge pull request #84 from basho/gh83-maven-incompat
