I'm currently playing around with JetBrains' MPS. While the documentation lists a few examples on how to create IntelliJ plugins from your custom languages (https://confluence.jetbrains.com/display/MPSD31/Building+IntelliJ+IDEA+language+plugins), I fail to find an example how you could incorporate your custom language in a Maven build. Does anyone know whether or not this is possible and if it is, how to do it?
ATM, you can only use MPS languages in Ant builds through the provided set of Ant tasks.
