Hi @ryl0125! I'm not being able to reproduce your issue. I've just build a personal project using JP 1.7.5 without problems. Are you sure com.example.demo.MainApp exists? Maybe are you trying to build your project directly from IntellJ?

I see this issue in 1.7.5 with this config:

I'm running with Java 21 with preview features. The app is JavaFX

I think the issue is running it from the maven menu in intellij. I think it uses "mvn javapackager:package" instead of "mvn package". The latter works for this now.

Thanks for the info!
