I've just created an empty project in IntelliJ Ultimate 2020.1, using Gradle and Kotlin build script. But IntelliJ isn't recognising my main method - no green arrow. Nor can it find it from "Add Configuration..."

class Launcher {

    fun main(args: Array<String>) {
        println("Hello world")
    }
}

IntelliJ didn't tab-complete either when creating main- I had to write it all out by hand.

try to write psvm somewhere in the file outside of the class

[mzgreen]

intellij should suggest you a quick action, tap enter and it’ll generate the main function

[v79]

So psvm can't happen inside a Kotlin class?

[mzgreen]

it has to be top level: https://discuss.kotlinlang.org/t/is-the-main-function-must-be-a-standalone-function/877

[mzgreen]

seems like @JvmStatic annotation should also work

I've been writing in Kotlin for a couple of years and completely forgot... been a while since I started a new project, clearly!

You could also place it in a companion object.
