Hi, I'm building my desktop app to an MSI but when...

# compose-desktop

[Graham Dean]

Hi, I'm building my desktop app to an MSI but when I run the .exe, nothing happens (the executable just exits immediately). I suspect there are some dependencies missing from the installed files. My app uses javafx and my build.gradle.kts has these dependencies in it. If I rip out the javafx dependencies and associated code, the app installs and runs fine. 1) How can I package up my app to run with javafx?, and 2) is there a way to diagnose the running of the .exe issue (e.g. any diagnostics or logs to view)?
build.gradle.kts excerpts:

plugins {
    kotlin("jvm") version "1.4.30"
    id("org.jetbrains.compose") version "0.3.0"
    id("org.openjfx.javafxplugin") version "0.0.9"
}
...
javafx {
    modules("javafx.controls", "javafx.swing", "javafx.media")
}

Thanks!

maybe your JavaFX dependencies are not picked up by the plugin. I’d suggest to check with jpackage developers on how better identify the issue. Our Gradle plugin provides task runDistributable which could be helpful here.

Thanks! It seems, for debugging the exe, being able to run jpackage with the --win-console option might be useful (https://stackoverflow.com/a/64614660/5670695). How can I change the jpackage options used by the Gradle tasks?
Note: for some reason, runDistributable fails to execute the app for me with:

Starting process 'command 'CorrectAppName.exe''. Working directory: C:\<correct path>\CorrectAppName Command: CorrectAppName.exe

CreateProcess error=2, The system cannot find the file specified

it could be signal of some native dll not found, like in https://github.com/openjfx/javafx-maven-plugin/issues/19. I'd suggest to add packaging required libs manually.

--win-console can be specified like this:

compose.desktop {
    application {
        nativeDistributions {
            windows {
                console = true
            }
        }
    }
}

Also you can check out the DSL reference here.

As for the runDistributable error: could you try a newer build (e.g. 0.4.0-build180)? I remember fixing a similar issue some time ago.

[Graham Dean]

Thanks @alexey.tsvetkov, @olonho. Updating to 0.4.0-build180 fixed the runDistributable 👍 That nativeDistribution DSL is just what I was looking for.
FYI: I did manage to run jpackage myself and set --win-console and discovered the missing packages, which I've added to the build.gradle.kts as follows. I don't think I would have worked it out without having the win-console output.

implementation("org.openjfx:javafx-controls:13")
    implementation("org.openjfx:javafx-swing:13")
    implementation("org.openjfx:javafx-media:13")

    // To resolve: java.lang.NoClassDefFoundError: "jdk/swing/interop/SwingInterOpUtils" when trying to jfxPanel.setScene()
    implementation(files("packaging-libs/jdk.unsupported.desktop-jdk15.jar"))

java.lang.NoClassDefFoundError: "jdk/swing/interop/SwingInterOpUtils"

Im facing this issue @Graham Dean
and I added

implementation(files("packaging-libs/jdk.unsupported.desktop-jdk15.jar"))

but ig this jar isnt at my side so how to do it >

[alexey.tsvetkov]

Have you tried adding jdk.unsupported.desktop module dependency?

compose.desktop {
    application {
        nativeDistributions {
            modules("jdk.unsupported.desktop")
        }
    }
}

If that helps, I recommend reading this section of the docs https://github.com/JetBrains/compose-multiplatform/tree/master/tutorials/Native_distributions_and_local_execution#configuring-included-jdk-modules
