Camel and Scala is a good combination,
but if you like to be on the bleeding edge and almost done converting your scala app to 2.10 you can find that camel still doesn't have a stable release supporting scala 2.10.
So SNAPSHOT will do the trick in this case, but you know... it's a SNAPSHOT :)
All you need is apache snapshots repo and camel-scala 2.11-SNAPSHOT
resolvers += "Apache Snapshots" at "http://repository.apache.org/snapshots/" libraryDependencies += "org.apache.camel" % "camel-scala" % "2.11-SNAPSHOT"
Add those to your sbt build and you are all set.
