Play 框架教程:无法解析符号“索引"? [英] Play framework tutorial: Cannot resolve symbol 'index'?

问题描述

我遵循了 仅适用于 IntelliJ IDEA Ultimate 版.>

I followed a tutorial here and although I got the entire tutorial working just fine, one of the classes in my IntelliJ project is marked with "red warnings". I cannot figure out what the problem is here? The project works but it shows these warnings? Any ideas on what this is and how to fix it? In the tutorial, about 3.5 minutes into it, the red marks magically disappear and the video presenter doesn't explain it.

解决方案

The Play 2.0 support plugin is only available in the IntelliJ IDEA Ultimate edition.
