I am just getting started with Play framework, I hardly converted the play-java project to eclipse project and imported it into the Eclipse IDE as eclipse required some additional plugin, I tried downloading the Scala IDE which has play supportive plugins inbuilt and imported the project, it works.
But when I open the two default html files, index.scala.html and main.scala.html, the editor shows errors as shown below.


How to resolve these setup issues? I am using the latest Play framework Play 2.4.2 and my Scala IDE downloaded file name: scala-SDK-4.1.0-vfinal-2.11-win32.win32.x86_64
