We currently produce weekly release of all of our artifacts which can be found here:

Unfortunately, making use of these is difficult for a variety of reasons. First, you need to identify the bundle that you want to roll back. Then you need to update the version of that bundle in your pom.xml. This isn't everything that you need though because it's possible that others are using the older version of the bundle which will cause incompatibilities, so you really need to convert every pom.xml (possibly in every project).

This means, that there is no meaningful way to roll back partially to a weekly release without either a script or some other form of support to roll back.

Some ideas I've heard tossed around are:

• A script that takes a bundle name and a version and changes the version for that bundle and changes the version to the specified one everywhere. This would likely even work for versions defined using variables.
• A script that basically just allows you to change between the latest weekly version and the latest snapshots for all bundles in all files at will.
