If I have more than one source dependency on an external project, and both projects make use of an SBT plugin, then the plugin versions are not shared and the classloader magix become as black as the dark heart of MORDOR (notice that resembles MURDER).

Here's a simple build which demonstrates the issue:

object SbtPluginProjects extends Build with rewire.DependencyAnalysis {
  val root = Project("sbt-plugins", file(".")) aggregate(appengine, assembly)

  lazy val appengine = RootProject(uri("git://github.com/sbt/sbt-appengine.git"))
  lazy val assembly = RootProject(uri("git://github.com/sbt/sbt-assembly.git"))

If you know of a workaround, please list it here!
