For Maven, at compile time the absolute paths of the jars in the local  
repository are used. In case of creating a distribution Maven is capable  
of detecting filename collisions, in which case the files will be renamed  
according to a strategy. Most common way is to prefix the name with the  
groupId, but the renaming strategy is up to the end-user.
This also made me aware that this would suddenly change the name of the  
automodule, unless the module-info is rewritten.
