Question

I’m trying to make a program using Netbeans 21 + Jdk 17 with Project Gradle
This program has a dependency on another project. This project has been obfuscated using Proguard 7.4.2

the obfuscation process that I do is

downlad the source code from https://sourceforge.net/projects/proguard.mirror/files/v7.4.2/7.4.2%20source%20code.zip/download
Then build using Netbeans 21 Jdk 17, the results are in the lib folder like:
- proguard.jar
- proguard-ant.jar
- proguardgui.jar
- retrace
run proguargui.jar
java -jar D:libproguardgui.jar

by using the Coba.pro file, here are the contents of the file
note: I copied the rt.jar file from Jdk 7
