in general it depends where is you jbpm-console running, if it on the same box as your development environment (both have access to the same local maven repo) then it's enough to go to jbpm console and use deployment panel to create new deployment unit. Otherwise you'll need to deploy (maven deploy) the artifact to repository jbpm console cas access to. Here you can find some options on how to deploy projects into jbpm console.
Thanks for the link Maciej. I will give it a go.
