Just a reminder for those still reading my little helper post on how to setup JAVA_HOME, ANT and MAVEN environment paths on MacOSX. I have just upgraded my mac to the latest JDK7 from Oracle and thought it would be nice to 'update' my post as well. I am already running the latest MacOSX 10.8 and I am quite happy with it. So...happy coding!
