Hi Guys! I am testing Proguard to apply for all Java project in my company. But after I run obfucate code my jar file cannot run as normal. Could you please help me to check. Here is the error I got:

java -jar tuanna.jar

And Here is the Configuration I used:


-verbose
-ignorewarnings

-injars       spring-boot-hello-world-example/target/spring-boot-hello-world-example-0.0.1-SNAPSHOT.jar
-outjars      tuanna.jar

-libraryjars /Library/Java/JavaVirtualMachines/jdk1.8.0_241.jdk/Contents/Home/jre/lib/rt.jar

-dontshrink
-dontoptimize
-dontobfuscate

Thanks in advance

Dear @tuanna2704 ,

Thanks a lot for posting your question here on the community!

To further assist you, could you please tell us how you are using Proguard? Based on the configuration file attached, I suppose you are using DexGuard Standalone, can you please confirm?
In addition, can you please check if this exception is thrown when you run the jar file you gave ProGuard as an input?

Kind regards,

Ewout
