I have tried proguard-7.1.0-beta5 where I tried to obfuscate my jar file. it does make the changes in the class and method names, but the contents of methods and class remain untouched. Can you please help me to understand what I am doing wrong?
below is my config file and steps I did.

Command I used: java -jar proguard.jar @democonfig.pro -verbose

Config File ‘democonfig.pro’ entries as below,
Note: RunMe is my main class.

-injars D:\ProGaurd\proguard-7.1.0-beta5\lib\RunMe.jar
-outjars D:\ProGaurd1\RunMe.jar

Hi @Batsi1984 ,

Welcome to the ProGuard community.

ProGuard is intended as a Java optimizer. Besides shrinking and optimizing the Java bytecode it will also apply name obfuscation to classes, methods, and fields as you noticed.

Unfortunately, it does not apply any further obfuscation techniques to the content of the methods. If you’re looking to obfuscate an Android application, we do offer a commercial solution (DexGuard) that will better suit these needs.

Best regards,
