Play - Querydsl not generating Q classes - scala

Question

I am new in using Play framework. I am trying to generate Q classes in play framework project. When I compile program using activator by running command compile it did not generate Q classes.
My build.sbt content is
import codetroopers.QueryDSLPlugin
import play.PlayJava
name := """trainers"""
version := "1.0-SNAPSHOT"
lazy val root = (project in file(".")).enablePlugins(PlayJava, QueryDSLPlugin)

My plugin.sbt:
resolvers += "Typesafe repository" at "https://repo.typesafe.com/typesafe/releases/"
// The Play plugin
addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.3.8")

Do I need to run any specific command to generate the classes. My Scala version is 2.11.7. My Activator version is 1.3.6.
