我认为他还在 Eclipse 的 Scala IDE 中实现了该功能，因此您也可以查看一下.最新的是 在线提供.

I think he also implemented the feature into Scala IDE for Eclipse so you also take a look at that. The latest is available online.

我想运行 Scala 代码作为测试的一部分，所以我实现了 CompilerMatcher 关注他的文章.

I wanted to run Scala code as part of testing, so I've implemented CompilerMatcher following his article.
