Intellij Idea setup for Scala, clarification needed
提问by James Raitsev
Using IntelliJIdea 12, i downloaded the Scala plugin and created a HelloWorld application.
使用 IntelliJIdea 12，我下载了 Scala 插件并创建了一个 HelloWorld 应用程序。
The following import seems odd. Why does IDEA not recognize this to be a Scala Application? Is my setup incomplete?
以下导入似乎很奇怪。为什么 IDEA 不承认这是一个 Scala 应用程序？我的设置不完整吗？
I checked to see where does my compiler points to and got this. Don't really see a way to navigate IDEA to my scala installation.
我检查了我的编译器指向哪里并得到了这个。真的没有看到将 IDEA 导航到我的 Scala 安装的方法。
Please advise.
请指教。

You need to add Scala as a framework for your project.
您需要将 Scala 添加为您的项目的框架。
To do this, right click on the top level directory in your project, choose "Add Framework Support..." and select Scala. Then Scala will be added as a "Facet" of your project.
为此，请右键单击项目中的顶级目录，选择“添加框架支持...”并选择 Scala。然后 Scala 将被添加为您项目的“方面”。

I got around this by downloading the Scala library from scala-lang.org, unzipping it and then pointing the project to it. It worked fine after that. But of course, I'm an eclipse guy so perhaps someone else might be able to give you a better automated (?) solution. Here's what my project looks like in Module Settings -> Libraries:
我通过从 scala-lang.org 下载 Scala 库，解压缩它，然后将项目指向它来解决这个问题。在那之后它工作得很好。但是，当然，我是一个 eclipse 人，所以也许其他人可以为您提供更好的自动化（？）解决方案。这是我的项目在模块设置 -> 库中的样子：
