Here is a post by a blogger who goes by the name of jribble in his blog Ribble’s Code. He gives a nice and easy to follow tutorial on how to automate JMeter (with the Maven plugin) with Jenkins (a branch of Hudson). He first starts up a default local Jenkins instance and adds a performance plugin (and if necessary a git plugin to pull projects from GitHub). Then he creates a new job in Jenkins. He goes on to give some required build steps to work with Maven and builds the project.
This post has some nice tips to get Jenkins and JMeter Maven working smoothly together and includes many screenshots.
He also has a previous post for making JMeter tests run in Maven which is definitely worth checking out as well.
