SBT Scala脱糖项目

如果我有一个小型/中型SBT Scala（带有Akka）项目，并且希望看到scalac的脱糖输出，我将如何做到这一点

我发现了一些用于显示小函数或类文件的示例，但这些示例不使用外部类（即导入）。我想看看ScalaTest中的一个函数是去糖化的，但是有太多的依赖项，一个简单的

scala-print myFile.scala

无法工作

对于如何做到这一点，我们将不胜感激。

使用SBT 0.13，您可以导出命令行，从命令行运行scala编译器，并在类路径上具有所有正确的依赖项：

> compile

您可以将其删除到感兴趣的文件中，然后添加

-print

或类似内容

有一次，我将其自动化，这样您就可以在SBT中使用一个新命令，

compilequick

但是我还没有检查这是否适用于当前的SBT版本。

对于SBT 0.13，您可以从命令行导出命令行以运行scala编译器，并在类路径上具有所有正确的依赖项：

我的方法是编译它，然后使用jd gui进行反编译。有时会搞砸，但可以帮助我理解99%的糖。
