Build.scala: specify scala version does not work

Question

I use playframework and here is my appDependencies in Build.scala:

  val appDependencies = Seq(
// Add your project dependencies here,
jdbc,
anorm,
"com.rabbitmq" % "amqp-client" % "3.0.1",
"com.typesafe.akka" %% "akka-agent" % "2.1.0",
"org.mongodb" %% "casbah" % "2.5.0",
"com.novus" % "salat_2.9.1" % "1.9.1",
"se.radley" % "play-plugins-salat_2.9.1" % "1.1"

)

There are no salat and play-salat plugins for scala 2.10 so I specify scala version explicitly. But it takes no effect:

What am I missing?

Since I'm getting the feeling you are trying to mix some Scala library compiled against Scala 2.10 with some other library compiled against Scala 2.9, don't do this! Really, if you don't want to shoot yourself in the foot, never, ever, mix libraries that are compiled against different Scala major versions (Scala versioning scheme is era.major.minor, hence 2.9 and 2.10 have different major version). The reason for this is that Scala only guarantees binary compatiblity across minor releases (shameless plug on binary compatiblity: slideshare.net/mircodotta/managin-binary-compa) — Mirco Dotta
