Versioning Software using Maven Versions plugin

I’ve had some experience with the Release plugin, but because of the number of times it commits to the repo, it cannot be used for Continuous Delivery.

Here’s an article that describes a workflow using the Versions plugin. It also leverages the fact that generally speaking, cloning a repo using a DVCS is quite fast, and much faster than it was using SVN. It also focused on reducing the number of steps. Basically, it does 1 clean/compile/test cycle, and doesn’t do any commits to the SCM. It merely tags the changeset in the repo.
