Hi

I've downloaded jbilling 3.0.1 comminity src from github, and I'm trying to build it as per the instructions on https://github.com/emilc/jbilling. However I'm unresolved errors, the log is below.
My build environment details:

Windows 7, 64Bit. Grails 1.3.7. Java version "1.6.0_22" Java(TM) SE Runtime Environment (build 1.6.0_22-b04) Java HotSpot(TM) 64-Bit Server VM (build 17.1-b03, mixed mode)

The "grails compile" log:
