Hi sebb, as you noticed, Hama uses Maven as a build system but, since this was added recently [1][2], the project "main" build is still based on Ant, therefore Hama still has the lib/*.jar versioned in SVN. Thanks for the hints regarding libraries' versions (but I wouldn't consider it a blocker) and grobo-testing-junit (I didn't manage to find it in any repo). Regards, Tommaso
