And to go along with this. Is there any way to apply the application plugin together with the kotlin multiplatform plugin?

[Sebastien Leclerc Lavallee]

I just did that and seems to work:

plugins {
    id "org.jetbrains.kotlin.multiplatform" version "$kotlin_version"
    id "org.jetbrains.kotlin.plugin.serialization" version "$kotlin_version"
}

apply plugin: 'kotlinx-serialization'
apply plugin: 'application'

[Sebastien Leclerc Lavallee]

🤔 Might not be that simiple. I’m currently moving to the new MPP plugin. I just did add the application plugin, generate the application but when executing, can’t find main class

[Big Chungus]

Just create custom Jar and JvmExec tasks and add your runtime classpaths. For Jar also configure main class in manifest. Goohle around on that and let me know if you still cannot figure it out

[fkrauthan]

@Big Chungus do you have any sample?

[Big Chungus]

I do, will post it tomorrow once i get to my pc

[fkrauthan]

Perfect thank you

[Big Chungus]

@fkrauthan, there you go:

afterEvaluate {
  tasks {
    val compileKotlinJvm by getting(org.jetbrains.kotlin.gradle.tasks.KotlinCompile::class)
    val jvmProcessResources by getting(Copy::class)
    val jvmRun by creating(JavaExec::class) {
      dependsOn(compileKotlinJvm, jvmProcessResources)
      group = "run"
      main = "lt.petuska.IndexKt"
      classpath = configurations["jvmRuntimeClasspath"] + compileKotlinJvm.outputs.files +
          jvmProcessResources.outputs.files
      workingDir = buildDir
    }
    val jvmJar by getting(Jar::class) {
      manifest {
        attributes["Main-Class"] = jvmRun.main
        attributes["Version"] = project.version
      }
    }
  }
}

[fkrauthan]

Cool that works :)

[Sebastien Leclerc Lavallee]

I add this at the end of the build.gradle ?

[fkrauthan]

Yeah. In addition to that I personally added

args = System.getProperty("exec.args", "").split(" ")

To the jvmRun command. This way I can use -Dexec.args="" to pass along command line arguments (not perfect but will do for some testing in my case)

[fkrauthan]

and I did add

from(kotlin.jvm().compilations.getByName("main").compileDependencyFiles.map { if (it.isDirectory) it else zipTree(it) })

to the jvmJar command to pack dependencies into my fat jar

[Sebastien Leclerc Lavallee]

Thanks, I’ll test these out later

[Sebastien Leclerc Lavallee]

Is it possible to do this in groovy gradle?

[Sebastien Leclerc Lavallee]

I did change to use a .kts file, I did run task jvmJar and the jar is produced. Now how can I use that jar file with the script? Thanks 🙂

[Big Chungus]

Just do ./gradlew jvmRun

[Big Chungus]

It will not produce jar, but rather compile project and run it directly

[Sebastien Leclerc Lavallee]

What I need is to use that jar file from another app. I’m creating a protoc plugin… I did manage to manualy change the .sh file generated from the gradle application plugin. Fingers crossed 🤞 kotlin multiplatform and application plugins will be working in the future

[Big Chungus]

Why not just have another jvmRun task like the one in my example that extends the classpath with the classpath of child project?

[Big Chungus]

or just add zipTree of that jar

[Sebastien Leclerc Lavallee]

I need to have something self contained. That why the jar file.
