I'm afraid the instructions in this Wiki have become broken, due to changes in the latest version of CAS. The problem is that the Wiki suggests you use the RELEASE version of CAS, and unfortunately the configuration changes over time. The best thing to do would be to look at the article history and work out the version of CAS that existed at the time the article was written. Then insert the appropriate versions into the maven POM. I'm sorry I can't be of more help at this point.
