java.lang.VerifyError when running obuscated jar

Hello,
I face an issue while running the obfuscated jar


Any idea please & thank you

Hi @Amira ,

This is potentially a bug in ProGuard’s optimization step, which version or ProGuard are you currently using?
If you’re not on the latest version, please update ProGuard and check if the issue persists. You can temporarily work around this issue by setting -dontoptimize in the configuration file.

Kind regards,

Jonas

Hello,
I already set -dontoptimise in my config file
Proguard Version: 6.3.0beta1
Thank you

Hi @Amira ,

Is it possible you have -dontpreverify somewhere in your configuration? If so, please remove it, the preverification step will add the stackmap frames.

Kind regards,

Jonas
