Set compile target to 1.6.  For some reason it used to compile before but doesn't now as my new maven install is default to Java 1.3... :(
Example error:
[ERROR] /aop/CommandPreprocessListener.java:[21,15] generics are not supported in -source 1.3
[ERROR] (use -source 5 or higher to enable generics)
[ERROR] public List<String> Disabled;
