I haven't built the entity module from scratch. What I usually do when I need to change something is to modify only the one file and compile only it, placing the identity jar file (and any other jars it needs) in my classpath. The compiler is then happy because it sees the related entity files. I then replace the class file in the entity jar with the newly compiled one.
