My approximation of nvie's git flow when using maven-release-plugin to cut releases. - http://nvie.com/posts/a-successful-git-branching-model/

maven-git-flow.sh

# How to perform a release with git & maven following the git flow conventions
# ----------------------------------------------------------------------------
# Finding the next version: you can see the next version by looking at the 
#	version element in "pom.xml" and lopping off "-SNAPSHOT". To illustrate, 
#	if the pom's version read "0.0.2-SNAPSHOT", the following instructions would 
#	perform the release for version "0.0.2" and increment the development version 
#	of each project to "0.0.3-SNAPSHOT".

# branch from develop to a new release branch
git checkout develop
git checkout -b release/v0.0.2

# perform a maven release, which will tag this branch and deploy artifacts to 
#	nexus (currently: http://10.202.4.52:8081/nexus )
mvn release:prepare
mvn release:perform

# merge the version changes back into develop so that folks are working against 
#	the new release ("0.0.3-SNAPSHOT", in this case)
git checkout develop
git merge --no-ff release/v0.0.2

# housekeeping -- rewind the release branch by one commit to fix its version at "0.0.2"
#	excuse the force push, it's because maven will have already pushed '0.0.3-SNAPSHOT'
#	to origin with this branch, and I don't want that version (or a diverging revert commit)
#	in the release or master branches.
git checkout release/v0.0.2
git reset --hard HEAD~1
git push --force origin release/v0.0.2
git checkout develop

# finally, if & when the code gets deployed to production
git checkout master
git merge --no-ff release/v0.0.2
git branch -d release/v0.0.2

jgitflow looks promising : http://blogs.atlassian.com/2013/05/maven-git-flow-plugin-for-better-releases/ .

I've created a script based on the instructions outlined by @vdemeester here: http://vincent.demeester.fr/2012/07/maven-release-gitflow/

It's fairly straightforward: https://gist.github.com/nwinkler/9213085

The jgitflow plugin looks nice indeed, but only works well when using SSH keys to access the repo. Since I can't do that in our current setup, I can't use the jgitflow plugin - it keeps asking for username/password on the command line. Due to that, it isn't easy to use in a scripted solution.
