Thanks. I moved on to sakai since Drools integration helper requires java 1.6.
Using https://github.com/sakaiproject/nakamura/tree/master/sandbox/drools/drools-maven-plugin I receive the following when compiling a MVEL rule
[ERROR] Unable to resolve ObjectType 'Car' : [Rule name='maserati']
[ERROR] Unable to resolve ObjectType 'Claim' : [Rule name='maserati']
[ERROR] Unable to build expression for 'consequence': [Error: Failed to compile: 2 compilation error(s):
