Open command prompt(Not Git-Bash prompt) and run the following commands....

  • play clean-all
  • play compile
  • play run Server should be getting started. Now come back to IDE(Eclipse) and refresh the project. If problem solved then njoy else try something else :)

It could be that you need to install sbt;

try running "sbt" in command prompt/console, If you get 

    Cannot find sbt launcher 0.13.0
Please download: 
  From  http://typesafe.artifactoryonline.com/typesafe/ivy-releases/org.scala-sbt/sbt-launch/0.13.0/sbt-launch.jar
    To  /home/<your home directory>/.sbt/.lib/0.13.0/sbt-launch.jar

then, follow its instructions, everything should work
