Hi all;
I was looking at the hibernate source code, obviously it is a maven project in a parent/module structure. I am having difficulty understanding the structure. It is very much maven related, but I was hoping some of the insiders of hibernate give an insight.

The main folder called core is has a pom which defines all the modules, it also defines a parent project which is one of its modules!!! How can the parent project be a module inside its child?

Would be very grateful for any clue.

Thanks
