CraftBukkit Build Issue

I'm running Bukkit/CraftBukkit on a Jenkins install as theres no up to date Maven Repository for CraftBukkit, Bukkit builds fine without issue and produces the JAR/POM into the local maven repository.

CraftBukkit on the other hand has a weird issue:

Code:

I've got no information on exactly what its failing on, and the project builds perfectly under Eclipse/m2e.

The Jenkins instance is running Maven 3.0.3 and JDK 1.5u22. Has anyone hit a issue like this before?
