I have an Eclipse based Scala project but can't install the current Scala plugin on just keeps failing with some random MD5 hash. So I've moved to Intellij Idea. I have the latest IDEA and imported my project through Git. The Cloning went fine and it recognized Scala files. But when I try to build from the Build.xml file in Ant I get an error about the SDK not being specified. But when I look at the SDK choices, none of them are Scala. How do I use the Scala JSDK??
