Make sure that your Jad path is correctly set in eclipse.
Start eclipse and open window> preferences> JAVA> jadclipse.
1. Path to decompiler. Set the full path name of The Decompilation tool Jad, for example, % java_home %/bin/jad.exe.
2. Directory for temporary files. Set the temporary file path here.

As for the parameter settings in the debug, direves ves, formatting, and MISC directories in the window-> preferences-> JAVA-> jadclipse directory, we will not be so arrogant.

(3) After the installation is complete, eclipse does not automatically set jadclipse class file viewer to the default open mode of the class file.

If no default value exists, modify "*. the Default Editor associated with class is jadclipse class file viewer ". After setting, double-click the *. Class file and eclipse will automatically decompile the file.
(3) install plug-ins in eclipse
