How do I change the default port 9000 in Play 2.3.x in the build definition?

With Play 2.2.x I can set the default port with the build.sbt ie file:

  play.Project.playScalaSettings

  play.Project.playDefaultPort := 9001

      

        
        
        
      

    

After update 2.3.x play.Project.playDefaultPort

no longer exists.

I do not want to type -Dhttp.port=9001

orrun 9001
