How can I embed sbt within my Scala program?

Question

I tried to embed SBT by creating a new SBT program and adding sbt-launcher.jar to the lib directory.

package testapp

import xsbt.boot._

object TestMain extends App {
  Boot.main(new Array[String](0))
}

However this fails to run with the following error.

Exception in thread "main" java.lang.IncompatibleClassChangeError: Expected static method scala.Predef$.refArrayOps([Ljava/lang/Object;)Lscala/collection/mutable/ArrayOps;

Can you provide more info - what do you expect from this code, your build.sbt and so on — Dmitry Meshkov, Jul 31 '15 at 07:00
ok i try but a bit later as I go to go out for dinner and things ... — Phil, Jul 31 '15 at 08:04
Current sbt uses Scala 2.10. If you try to host that in Scala 2.11, that won't work. — 0__, Jul 31 '15 at 08:34
