Building maven project in Bamboo gives me an empty jar - eclipse

Question

I'm working with Eclipse, Maven 2.0 and Bamboo. I checked out a project from GitHub and debugged it in Eclipse. I had it ready and when I exported the JAR from Eclipse I got a 76KB JAR (which is correct), but when I make Bamboo use a plan to build the same JAR using a maven pom.xml file, Bamboo gives me a 1KB JAR saying there's nothing to compile.
What am I missing? Here's my pom.xml file:
