The main reason for this fork is the upgrade to selenium 2.0rc2. I did this mainly to upgrade selenium to 2.0 with webdriver so I could test facebook canvas apps more easily. The inspiration came from this post
This fork upgrades everything to grails 1.3.7, for the spock test suite spock-core is upgraded to 0.5-groovy-1.7.
You should install gradle build tool. Then just do a gradle in the project root folder. If everything is ok you didn't brake anything. If it fails fix before pushing.
