How to link source from outside of maven project?

问题

In Maven, is it possible to link additional dependent java src from outside the project folders, so that when we build our main package, maven may include such classes into final jar?
just as we can link any source folder to our project in Eclipse and eclipse treats it as regular project source?

Technically, it's possible to add source folders to a build and this is usually done using the build-helper-maven-plugin. However, I would recommend against doing so for directories outside a given module, a maven module should be self contained.
