As far as I know console currently can access only artifacts from the defaultPackage so you should place your processes in that package. More over make sure that console successfully connects to Guvnor (make sure that changeset.xml file is available to the console). As you could see there is a problem with that:
12:47:42,239 INFO [STDOUT] 12:47:42,239 ERROR [CommandDelegate] Could not load processes from Guvnor: null
