Rollback with Hudson and Maven?

I've been thinking about implementing rollback with Hudson and Maven. Our projects consists of multiple subprojects which are packaged into .war -files. If these were deployed into Maven repository, it would be possible to use Hudson's "redeploy" artifacts to deploy older versions. After this, you could have a job in Hudson which does the actual deployment to application server.

If that deployment job had dependencies to the .war -files, Hudson might actually spot these changes and do the deployment job automatically after redeploy. I definitely have to check this out.

(Almost) Continuous deployment with Gerrit and Hudson

Here's a somewhat simplified workflow for continuous deployment when working with Gerrit and Hudson.

As you can see, features are deployed into Beta server instead of production server. This is mandatory when working with corporate clients, they don't want to have real continuous deployment.
