Multi-module Maven project with Flat or Hierarchical structure?

[Tibi Kiss]

There are some pros and cons to choose Flat or Hierarchical maven project structure.

If I choose a hierarchical structure in the Eclipse environment with m2eclipse plugin, seems to have some problems when using CVS instead of SVN.
Several mounth I have been involved in using hierarchical multi-module maven projects with Subversion repository. On a different location now I have to use CVS and when I checkout a hierarchical multimodule project it seems that I have several problems.
The team would like to use flat structure which option seems to be reasonable choice if I consider the previously mentioned issue with CVS repo.

But I know that maven-release-plugin it has some issues on flat structured multi-module maven projects.

Since I never been used flat structured multi-module projects, I would like to ask you if you have experience with them.

SVN does seem to lend itself better to hierarchical structure. It's not that you can't check out subtrees of CVS, but it's not as convenient.

When I did do complex projects in CVS, I made each module a separate project. That maps well in Eclipse where a CVS project and an Eclipse project are usually effectively the same thing.

Thank you!

At least now I have a feedback that not just for me it seems that it is related to CVS.
