我想查看从我自己的源代码生成的代码，但似乎IDEA没有使用IntelliJ API Decompiler使用新的fernflower插件反编译它们。
至少我有标题评论
// IntelliJ API Decompiler stub source generated from a class file
// Implementation of methods is not available
和那样的方法：public void update() { /* compiled code */ }
同时，在外部库（例如JDK）中，我看到了正常的头文件和反编译代码。
// Source code recreated from a .class file by IntelliJ IDEA
// (powered by Fernflower decompiler)
我可以使反编译工作，如果我将代码编译为jar并将其添加到某个模块，但它看起来不像一个普通的解决方案。
我可以使用fernflower使IDEA反编译任何类文件吗？
编辑：打开文件时，我在IDEA日志文件中得到一个异常。请参阅片段。

</pre>在我的情况下，问题是我安装了“Java Decompiler IntelliJ Plugin”。 Unistall它可以完成这项工作。
