Failed to open editor: The editor could not be initialized. NoClassDefFoundError

I can import the Play2 project into eclipse and work with scala files, but the problem is that I cannot open image files like 'index.scala.html'. When I try to open the file, I get the following error.

Failed to open editor: The editor could not be initialized.

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

But there is no problem opening other files. I do not know what happened. By the way, I used the typeafe activator to create a game project.

I would be grateful for any suggestions, solutions or workarounds to get it working.

Thank.
