I can import the Play2 project in eclipse, and work on scala files, but the problem is I can't open view files likes 'index.scala.html'. When I try to open the file I get following error.

Could not open the editor: Editor could not be initialized.

java.lang.NoClassDefFoundError: scala/util/parsing/input/Positional

at org.scalaide.play2.templateeditor.lexical.TemplatePartitionTokeniser.getScalaCommentAndPlainRegions(TemplatePartitionTokeniser.scala:28)

................

But there is no problem opening other files. I don't know what's wrong.

btw, I used typesafe-activator to create play project.

I will appreciate any suggestions, solutions or workarounds to make it work.

Thank you.
