Exclude specs2 as transitive dependency of play framework in sbt

Question

I'm trying to use specs2 v3.10.0 with Play Framework v2.2.3 but Play depends on specs2 v2.1.1 and it seems like they are interfering with each other.

In my plugins.sbt file, I have:

addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.2.3" exclude("org.specs2", "specs2"))

See the Dependencies file of Play Framework 2.2.x

Here is a screenshot of my Ivy resolution cache report showing the two versions of specs2 getting resolved as test dependencies:

Plugin dependencies are not resolved to test dependencies as far as I know. You probably need to exclude the dependency in the build.sbt, not in the plugins.sbt.
