How to share common properties among several maven projects?
I have several projects built by maven, and I want to share some common properties among them - spring version, mysql driver version, svn base url, etc. - so I can update them once and it will be reflected on all projects. 

I thought of having a single super pom with all the properties, but if I change one of the problem I need to either increment its version (and to update all the poms inherit from it) or to delete it from all the developers' machines which I don't want to do.

Can specify these parameters externally to the pom?
