I'm trying to develop on the Scala compiler project with the help of ScalaIDE. I followed this guide to set up the development environment. When I now try to build the mentioned projects, the reflect project won't get built. Instead, I get the following error via the console output:

uncaught exception during compilation: scala.reflect.internal.MissingRequirementError    reflect     Unknown Scala Problem

Having tried the provided ANT script of the project via the console, everything seems to work fine.

Does anyone know if I'm missing a hidden compiler flag, dependency or something like this?

Thanks!

With the IDE for Scala 2.10 you can only build the 2.10.x branch of the Scala compiler. If you want to work on master, you need to install a 2.11-based version of the IDE. We don't publicise IDE for 2.11 nightlies yet, but they are available at:
