can't import artifact with classifier when doing multi-project build

Say I have a root project definition in project/build.scala:

import sbt._
import Keys._

object Test extends Build {
  lazy val foo = project in file("foo")
  lazy val bar = project in file("bar")

  val base = "org.apache.james" % "apache-mailet-base" % "2.5.0"
  val baseTest = "org.apache.james" % "apache-mailet-base" % "2.5.0" % "test" classifier "tests" classifier ""
}

and foo project in foo/build.sbt

libraryDependencies ++= Seq(Test.base, Test.baseTest)

and bar project in bar/build.sbt

libraryDependencies ++= Seq(Test.base)

Import this with IDEA13 and scala plugin 0.41.2 leads to single library entry without artifact with test classifier in project structure.

On the other hand, if I include only foo project in root, import leads to single library entry with artifact with test classifier but in scope compile.

What I expected would be two library entrys and one with artifact with test classifier in scope test.
