That is partially correct. Intellij doesn't use zinc, but it uses the same compilation system that is at the heart of zinc. From http://blog.jetbrains.com/scala

That is partially correct. Intellij doesn't use zinc, but it uses the same compilation system that is at the heart of zinc. From http://blog.jetbrains.com/scala/ http://blog.jetbrains.com/scala/, there is a section showing how their new system relates to zinc. It would have been more accurate for me to say that this release the Scala team developed an SBT incremental compiler that is used by Eclipse, Maven, and, most recently, IntelliJ.
