问题描述

我可以在eclipse中导入Play2项目，并可以处理scala文件，但是问题是我无法打开诸如"index.scala.html"之类的视图文件.当我尝试打开文件时，出现以下错误.

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.

但是打开其他文件没有问题.我不知道怎么了 顺便说一句，我使用typesafe-activator来创建播放项目.

But there is no problem opening other files. I don't know what's wrong. btw, I used typesafe-activator to create play project.

我将不胜感激任何建议，解决方案或变通办法.

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

谢谢.
