IntelliJ 2021.2.3 中的 Kotlin 控制台应用程序 -> 无法在运行/调试配置中添加主 class“MainKt”

Question

I have created a new Kotlin Console Application in IntelliJ using Project JDK openjdk.17.

I have changed the gradle version to 7.3 in the file gradle/gradle-wrapper.properties:

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-7.3-bin.zip
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists

When I create a Kotlin Console Application project in IntelliJ it creates a file named "Main.kt". The file is not a class, but a function:

fun main(args: Array<String>) {

}

On one of my computers at home I can run the program by clicking the Run button (SHIFT+F10) in IntelliJ. On another computer with the same setup the Run button is grey. Here I need to add a Run/Debug Configuration.

In "Run/Debug Configuration" I select + then Kotlin. In Main class I cannot select "MainKt".

What I have tried:

• Invalid cache/Restart
• Create new project, but I get the same problem

My source code:

src\main\kotlin\Main.kt:

fun main(args: Array<String>) {
    println("Hello World!")

    // Try adding program arguments via Run/Debug configuration.
    // Learn more about running applications: https://www.jetbrains.com/help/idea/running-applications.html.
    println("Program arguments: ${args.joinToString()}")
}

build.gradle.kts:

import org.jetbrains.kotlin.gradle.tasks.KotlinCompile

plugins {
    kotlin("jvm") version "1.5.10"
    application
}

group = "me.admin"
version = "1.0-SNAPSHOT"

repositories {
    mavenCentral()
}

dependencies {
    testImplementation(kotlin("test"))
}

tasks.test {
    useJUnit()
}

tasks.withType<KotlinCompile>() {
    kotlinOptions.jvmTarget = "1.8"
}

application {
    mainClass.set("MainKt")
}

gradle.properties:

kotlin.code.style=official

settings.gradle.kts:

rootProject.name = "untitled"

gradle\wrapper\gradle-wrapper.properties:

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-7.3-bin.zip
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists

Answer 1

After debugging I found out that I could make a run configuration file manually by creating a directory and a XML file.

.run/MainKt.run:

<component name="ProjectRunConfigurationManager">
  <configuration default="false" name="MainKt" type="JetRunConfigurationType" nameIsGenerated="true">
    <option name="MAIN_CLASS_NAME" value="MainKt" />
    <module name="untitled.main" />
    <shortenClasspath name="NONE" />
    <method v="2">
      <option name="Make" enabled="true" />
    </method>
  </configuration>
</component>

You can change untitled.main with the name of your project.
