But main purposes of this libraries are be part of EJB3 product so I think it should be versioned in one way with one version number for releases of all libraries. So change in library-a should increase version in all libraries ? I have two arguments. 1) It takes time/resources away from dev to re-release projects with no changes. 2) If there's no difference in the code between 1.0.0 and 1.0.1, what does bumping the version number accomplish? You're labelling a new version, signalling that some change has been made. It seems like your concerns would be alleviated with another matrix showing all component versions that comprise an EJB3 release?
