Where in build.sbt to put PlayKeys.devSettings?

[Rapierian]

Hello, per this page the solution to my play.core.server.ServerStartException: No ServerProvider configured with key 'play.server.provider' Error would seem to be to add a PlayKeys.devSettings += "play.server.provider" -> "play.core.server.AkkaHttpServerProvider" somewhere in my build.sbt file, but I can't seem to find a location to do so that doesn't generate a "Reference to undefined setting"

Can you post (at least part) of you build.sbt? Did you enable the PlayScala or the PlayJavaPlugin?

Ah, that was it. I didn't realize that the project didn't have the PlayScala plugin enabled.
