Using grails 2.1.1, I have java source code in a folder called grails-app/lcs/src/java/, required no special configuration to add this to the build. But "grails doc" generates no javadoc output in the target/docs/api folder.

Documentation on this is sparse- how do i configure this in grails?
thanks,
