Maven naming conventions for hierarchical multiple module projects

Question

I\'ve got a question on Maven naming conventions (groupId, artifactId and directory names) in a multiple module project with a hierarchical directory structrure.

In earlier days with maven I followed the following structure which you have described:

appname
  +--- appname-module1
  +--- appname-module2
              +--- appname-module2-chhild1
              +--- appname-module2-chhild2
  +--- appname-module3

But this will become ridiculous if you get more levels.

So I decided to change my mind and now using things like:

appname
  +--- module1
  +--- module2
          +--- chhild1
                 +--- subchild1
          +--- chhild2
  +--- module3

The only thing which I change through the levels is the groupId...

appname (groupId: com.soebes.appname)
  +--- module1 (groupId: com.soebes.appname.module1)
  +--- module2 (groupId: com.soebes.appname.module2)
          +--- chhild1 (groupId: com.soebes.appname.module1.child1)
          +--- chhild2 (groupId: com.soebes.appname.module1.child2)
  +--- module3 (groupId: com.soebes.appname.module3)
