Build error in game infrastructure

I'm new to building a framework and just trying to get a basic java-play (hello-play-java) application running. But whenever I try to build it, it gives this error: -

error: object Project is not a member of package play
import play.Project._
        ^
Type error in expression
Failed to load project.`

      

        
        
        
      

    

My build.sbt file looks like this: -

import play.Project._

name := """hello-play-java"""

version := "1.0-SNAPSHOT"

libraryDependencies ++= Seq(
"org.webjars" %% "webjars-play" % "2.2.2", 
"org.webjars" % "bootstrap" % "2.3.1")

playJavaSettings


fork in run := true

      

        
        
        
      

    

I tried looking for it but didn't find much help.
