1. do you have latest? when did you fetch last (I can fetch the same
commit hash to make sure it compiles, I have latest and it compiles)

2. let try to compile the engine without the GWT stub -
 $ovirt_engine_home> cd backend/manager
 $ovirt_engine_home/backend/manager > mvn install -DskipTests

What is the result of the above?

BTW if you want online help I am on the ovirt IRC channel.
