Hi all,

I have an issue when I make package for desktop app (behavior is the same for mac and windows11).

Application runs normally from IDE or if I use gradlew.bat run on any machine.

But if I install the packed (deb or msi) It will just try to start? happens in a sec, small loading spinner near cursor and done. App never starts. There is no any error I can tell you.... I get nothing...

Last thing I've added to the app was Koin with annotations (ksp).

Does this require adding anything for the build?

You could try redirecting System.err to a file right at the very start of your main, and see if it’s the app that crashes.

The first thing to do should be to run the gradle task “runReleaseDistributable” from your IDE. Most problems of this kind can be located already this way.

@Michael Paus thank you!! This is the way. Feel so stupid, I did not know this exists.

Error is (Unsupported version number [65.0] (maximum 62.65535, Java 18))

Now I just have to figure it out, but at least I have some input now.

You’re compiling for Java 21

[Michael Paus]

If you want to use Java 21 for packaging you also have to use the latest ProGuard version which can be configured this way:

buildTypes.release {
    proguard {
        version.set("7.4.2")
        isEnabled.set(true)
        optimize.set(false)
        obfuscate.set(false)
        configurationFiles.from(project.file("compose-desktop.pro"))
    }
}

thank you!

It worked with java 17, but with this setup from you it works also with java 21!
Thx a lot!
