Taken from this tip.

Useful as a branch point for Maven projects; e.g.,

git checkout -b 1.23.x `git first-child this-project-1.23`
mvn versions:set -DnewVersion=1.23.1-SNAPSHOT
git commit -a -m 'Prep for 1.23.1'

retains

<tag>HEAD</tag>

and anything else besides <version>s that might have changed in the [maven-release-plugin] prepare for next development iteration commit.
