intellij-idea - Intellij 不会显示某些 kotlin 类的源代码

Question

我在研究 Kotlin 时，在查看一些文档时偶然发现了一些问题。我看到有些类没有附上源代码。例如，似乎没有 SetsKt.class 的源代码/javadoc，尽管其他类有很多。这有什么具体原因吗？

亲切的问候，杰尔默

引自 jetbrains 问题:

The reason for this behaviour is that facade class files (like FilesKt.class) can be generated from several kotlin source files. So when you click on such a file it's not entirely obvious what you want to see. So we went with a conservative decision to show (admittedly ugly) decompiled code for such files, which contain all the declarations inside as opposed to showing some source file (which may not contain the declaration you're looking for). We can improve the behaviour so that when class file is generated from only one Kotlin file it takes you to that file directly but this will not necessarily help with more complex cases (such as kotlin-runtime) when single class file is generated from several source files.
