scala - 构建 Intellij Scala 插件时出错

Question

我正在尝试按照说明进行操作

https://confluence.jetbrains.com/display/SCA/Setting+up+Scala+plugin+project+in+IntelliJ+IDEA

我正在使用 Idea 14.1.14。
已经下载了源码和downloadIdea。
导入项目后，将项目 SDK 设置为 1.7。

不确定以上信息是否足够继续；但在 make 项目中，我收到以下错误；有没有可能猜出我有什么不正确？

Answer 1

转到 File -> Project structure -> Global libraries 并在那里添加 Scala SDK。就我而言，两个 SDK 已经存在(在 ivy 文件夹中)并可供选择。
