It's actually out for quite a while now (and therefore already slighly out of date) but I have hardly found some time to blog about it: If you're using JRebel and JBoss Forge, have a look at this Video tutorial how to use both of them together.
Make sure to watch it in HD and full screen mode. Thanks to Chris "Kubrik" Reimann for putting the tutorial together!
As an addition, Forge now also supports checking out specific versions of a plugin, which is in our case version 1.0.0.Beta1 of the JRebel plugin. We've also added the plugin to the Forge plugin repository index so you can search for it.
By the way, if you're only using one of the tools or (even worse) none of them, this is the perfect opportunity to get a quick hands-on.
