How to deal with name collision when you try to deobfuscate weird code?
问题
我现在正在进行一个应用程序的逆向工程，并且希望能够对其进行修补（提取源代码，重新编译并重新构建）。我开始使用JD-GUI，但发现了一个非常有趣的混淆方法。
所有的类名都是同一个单词（lolkekcheburek），只是大小写不同：
因此，对于JVM来说，所有的类名都没问题，但当你尝试提取它时，Windows会提示名称冲突：
你会如何处理这个问题？
英文:
i am reverse engineering one application now and i want an ability to patch it (extract sources, recompile and build it again). I started with JD-GUI but found very interesting obfuscation method.
All class names are the same word (lolkekcheburek) but in various case variations:
So, for JVM all classes names are fine, but when you try to extract it, Windows notifies about name collision:
How would you deal with this?

默认情况下，Windows 对文件名不区分大小写。如果您真的想在 Windows 上进行操作，您需要在 Windows 10 上启用对特定文件夹的大小写敏感性：
fsutil.exe file setCaseSensitiveInfo C:\folder enable
英文:
By default windows is not case sensitive for the filename. If you really want to work on windows, you have to be on Windows 10 and enable case sensitivity for your specific folder with :
fsutil.exe file setCaseSensitiveInfo C:\folder enable

最简单的方法可能是使用类似 proguard 的混淆工具来“混淆”类和方法名称，但实际上它会将它们命名为 Class1、Class2 等等。但要注意，这可能会破坏一些依赖于堆栈跟踪的混淆技术。
英文:
The easiest way would probably to use an obfuscator like proguard to "Obfuscate" the class and method names again, but it will actually name then Class1, Class2 and so on. But be aware that this might break some obfuscation techniques that rely on the stacktrace.
