对于OSX，我建议使用jarzilla或JD-GUI

它们都允许你查看罐子、战争等。文件内容并反编译其中的任何类文件。

我尝试了几种，Procyon似乎最适合我。它正在积极开发中，支持最新版本Java的许多特性。

以下是我尝试过的其他方法:

CFR Promising, but often failed method decompilation. I'll be keeping my eye on this one. Also actively developed with support for the latest Java features. Krakatau Takes a different approach in that it tries to output equivalent Java code instead of trying to reconstruct the original source, which has the potential of making it better for obfuscated code. From my testing it was roughly on par with Procyon, but still nice to have something different. I did have to use the -skip command-line flag so it wouldn't stop on errors. Actively developed, and interestingly enough it's written in Python. JD-GUI Worked, but Procyon's output was much better. Here's a page comparing Procyon output to the original and JD-GUI. JD-GUI is also available as an Eclipse plugin, which didn't work for me at all. Doesn't seem to be open source and development seems sporadic. JAD Worked, but only supports Java 1.4 and below. Also available as an Eclipse plugin. No longer under development.

以下是截至2015年2月的反编译器列表:

Procyon，开源，https://bitbucket.org/mstrobel/procyon/wiki/Java%20Decompiler

CFR，免费，没有源代码，http://www.benf.org/other/cfr/

JD，仅供非商业用途免费，http://jd.benow.ca/

Fernflower，开源，https://github.com/fesh0r/fernflower，

JAD -此处仅为历史原因。免费，没有源代码，http://varaneckas.com/jad/ 过时，不受支持，不能正确反编译Java 5及更高版本。

您可以在线测试上述反编译器，不需要安装，并做出自己的选择。

云中的Java反编译器:http://www.javadecompilers.com/

Soot是较新的Java代码的一个选项。至少它的优点是最近还在维护……

此外，Java反编译器是一个具有独立GUI和Eclipse集成的反编译器。

最后，还没有提到Jdec，尽管它没有其他选项那么完善。

JAD不为我工作(Ubuntu 11.10问题)，所以我已经前进和浸泡在JODO。至少它有Open Java源代码，并且能够正确地反编译我的.class。

我建议先查看“分支/通用”分支。树干不稳。

JD-GUI真的很好。您只需打开一个JAR文件，然后浏览代码 你正在开发一个IDE。好东西。
