This library is currently available only via the maven2 snapshot repositories. You'll need to include that repository as a maven plugin repository as well as the necessary project dependencies. A sample project using this library might look like:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
