libraryDependencies <<= (scalaVersion, libraryDependencies) { (sv, deps) =>
  // If we're compiling on 2.11, we need to haul the reflection library
  // in separately, since it's no longer bundled in 2.11.
  if (sv.startsWith("2.11.")) {
    deps :+ "org.scala-lang" % "scala-reflect" % "2.11.0"
  }
  else {
    deps
  }
