hey there! Is there any clean way to get executable JAR of an application build with Kotlin MP? I've found a ticket here with some solution: https://youtrack.jetbrains.com/issue/KT-50227/MPP-JVM-target-executable-application which seems to be Open so started wondering if there's any other approach. Is anyone here aware of any other solution to this?

Does executable JAR mean a standalone excutable bundle similar to` .exe` or .app or .dmg in mac?

[Konrad Stanik]

yes, basically an equivalent of .kexe which can be easily exported by binaries.executable() available for Native

If your goal is to have an archive with the Java executable, the application plugin can generate it easily: https://gitlab.com/opensavvy/notes/kotlin-fullstack/-/blob/main/app-cli/build.gradle.kts?ref_type=heads

Note the:
• application in the plugins block
• the jvm { withJava() } block (mandatory, but not documented anywhere!)
• the application block with the main class
The plugin generates either a .zip or .tar.gz which contains a script that starts the application. It's not a single executable JAR, but in my case that was what I was searching for.

looks promising, will give it a try, thanks!

You can also create native distributions like .exe,.app

[Konrad Stanik]

this one is applicable to Compose MP I believe

[Spoudel347]

Yes, you are correct

also something like shadowjar (https://github.com/johnrengelman/shadow can be used, if you want to produce a single shaded jar with all your dependencies.

here are a few non-multiplatform examples:
