Eclipse中查看jar包中的源码

Java Decompiler Plugin For Eclipse IDE

1. 下载JAD ,
 1.5.8版本的jad在 http://www.softpedia.com/progDownload/JAD-Download-85911.html 

将展开后的jad.exe放到某个目录，例如 c:/jad/jad.exe

2. 下载JADClipse插件

http://sourceforge.net/projects/jadclipse/files/ 
将展开后的net.sf.jadclipse_3.3.0.jar放入Eclipse的plugins子目录下

3. 启动Eclipse
    注意：eclipse需要重新启动

4. 配置Jadclipse, 在 Windows - Preferences - Java - JadClipse下
配置Jad的路径为 C:/jad/jad.exe;

只需编辑这一个值就ok了

 

如下图所示

 

5：eclipse重新启动，即可。

 

6：

In Eclipse, try F3 into any class which does not has the source, Jad will decompile it automatically.

see examples :

运行过程中可能出现的错误：

  错误原因：

   Make sure your “jad.exe ” in existed in that folder.

     配置Jadclipse, 在 Windows - Preferences - Java - JadClipse下
    配置Jad的正确路径。

其他：

Juno Eclipse版本需要

 配置文件关联关系，在Preference中file associations中配置*.class & *.class without source 的default editors为jad，到此就可以使用jad的反编译功能了。
