Missing JavaFX runtime

[carrot-cookie]

Here is my build.gradle file (Gradle 6.1.1):

plugins {
    id "org.jetbrains.kotlin.jvm" version "1.3.72"
    id "application"
    id 'org.openjfx.javafxplugin' version '0.0.9'
}

version "0.1"
group "com.liberty.client"

repositories {
    mavenCentral()
    jcenter()
}

javafx {
    version = "12"
    modules = ['javafx.controls', 'javafx.graphics']
}


dependencies {
    implementation("no.tornado:tornadofx:1.7.20")
    implementation("org.jetbrains.kotlin:kotlin-stdlib")
}

compileKotlin {
    kotlinOptions.jvmTarget = "11"
}

compileTestKotlin {
    kotlinOptions.jvmTarget = "11"
}

Client.kt:

class Client: App(MyView::class) {
    fun main(args: Array<String>) {
        launch<Client>(args)
    }
}

MyView.kt:

class MyView: View("Login") {
    override val root = vbox {
        button("Press me")
        label("Waiting")
    }
}

When i try to start application, i get error:

Error: JavaFX runtime components are missing, and are required to run this application

Took adjustment data from guide.

What could be the problem?

Try moving the main function outside of the App class.

JavaFX can either run the class Client, or launch it from the main Kotlin function (treated like a class by the name of MainKt). I suspect when you launch from inside the app class, it can only access resources within that class, excluding the javafx runtime.

Hello! I did as you said. But compiler says me: Error: Main method not found in class com.app.Application, please define the main method as:

I notice gradle run works best, and my small app is starting. But there is another problem: it works without main function. if I add a main function I get an error:

add Kt to the class name, main.kt -> MainKt
