Maven Builder Helper plugin really helpful

I think I am dumb, cause I just found out this amazingly helpful maven plugin, Builder Helper.

Why? Just take a look at goals its supports:

• build-helper:add-source Add more source directories to the POM.
• build-helper:add-test-source Add test source directories to the POM.
• build-helper:attach-artifact Attach additional artifacts to be installed and deployed.
• build-helper:remove-project-artifact Remove project's artifacts from local repository.
• build-helper:reserve-network-port Reserve a list of random and unused network ports.

The first two allows your maven project using additional directories other than 'main/java' or 'test/java' as your source directories. And these additional directories are involved into standard maven building process.
