I have recently read people from Springsource stating that Maven 3 has issues for Spring Roo projects and that Maven 2 is recommended. Is this an official view of what's the best practice for Spring Roo projects?

If this is the official view does this also mean Roo users will be better off installing Maven 2.2.1 and use that in the preferences of Springsource Tool Suite? Which does come with Maven 3.0.3 as an optional install.

What are the problems avoided using maven 2.2.1 in favor of 3.0.3?

I use Roo 1.2m1 under jdk 1.5 myself, so it's the Spring 3.0.6Release Framework that I use.
