How re recreate project linkages from decompiled JAR using JD-GUI?

Question

I have a legacy .JAR file. I am able to de-compile it with JD-GUI, but this gives me a set of class files. I am trying to follow code through but there is limited linkage between the various classes.

I can follow the code manually, but is there a way to "re link" or create a project, so that I can navigate more easily.

JD-GUI does this partly when it underlines certain classes, but only takes me to the class. I would like to go direct to a declaration or see all usages.

Answer 1

If I understand your question, you want options similar to eclipse Goto references and declarations etc.

• Open JD-GUI and JAR file from it
• Select Save All sources option it will create zip file with source
• Now extract the zip into a folder
• Open eclipse and create java project.
• Copy the extracted content and paste it in src folder in eclipse

Answer 2

To work more effective you can do the following.

• Open Eclipse IDE, press CTRL + N, choose the option Java Project.

• Unchecked the option Default Location, search the project folder decompiled

• Choose the project, checked the option Default Option again and finish the Wizard.

With this steps you will ready to work.
