  3. Added the necessary references to build.sbt

    import NativePackagerKeys._
  4. Changed procfile as follows:

    web: target/universal/stage/bin/<appname> -Dcom.twitter.finatra.config.env=$ENV -Dcom.twitter.finatra.config.adminPort=$ADMIN_PORT -Dcom.twitter.finatra.config.port=:$PORT


  1. I added the $ADMIN_PORT environment variable so I can run formate start on the local command line to have the app boot via the Procfile.

  2. I added $ENV for the same reason, so that the development or whatever environment can be passed locally while still using the production style startup process.
