I want to pre-compile my .drl files to .class files so they do not have to be compiled a run time. The documentation makes it sounds like the kie-maven-plugin does this, but it is not generating anything for me. It compiles the rules files but does not output anything. Any suggestions?

I'm using the mvn package command, and my `pom.xml` file is below:
