Hi. How do I set main class directly from commonMain? Here is my build script for the module I have

plugins {
    kotlin("multiplatform")
    kotlin("plugin.serialization")
    application
}

repositories {
    mavenCentral()
}

application {
    mainClass.set("MainKt")
}

kotlin {
    jvm {
        val main by compilations.getting {
            kotlinOptions {
                jvmTarget = JavaVersion.VERSION_11.toString()
            }
        }
    }

    sourceSets {
        val commonMain by getting {
            dependencies {
                implementation("org.jetbrains.kotlinx:kotlinx-cli:0.3.5")
            }
        }
        val jvmMain by getting
    }
}

There is main.kt file with main() function inside commonMain source set. It also has the run button but when I try to run it this happens

Error: Could not find or load main class MainKt
Caused by: java.lang.ClassNotFoundException: MainKt

This should be correct. You can see the classes in the build folder for debugging. Or send more details.

It looks like this

[Giorgi]

I already had a project and this is just a new module

[Giorgi]

If there is main,kt inside jvmMain and I run it, then it works

[Giorgi]

it is as if there is some kind of limitation to commonMain

The application plugin, doesn't know how to properly play with kotlin multiplatform plugin

[hfhbd]

It does, you need to use jvmTarget { withJava() }

Thanks, it works now.

I wish Kotlin had better errors...

[Giorgi]

wait, this fixed the application plugin task. The green button does not work

Hm, this is another Kotlin Idea Plugin error (KTIJ) project at youtrack
