how do I fix Unresolved reference: javafxplugin?

Question

How do I apply the plugin for JavaFX using the Kotlin DSL? The manual suggests:

apply plugin: 'org.openjfx.javafxplugin'

Whereas I'm using the Gradle Kotlin DSL, rather than plain-vanilla Gradle.

Current error:

I'm looking to run the sample from JavaFX.

The Gradle plugins portal provides examples for declaring the plugin in both Groovy and Kotlin. The README of the GitHub repository also provides examples in each language. Basically, applying the plugin looks like:

plugins {
    application // built-in plugins are declared differently
    id("org.openjfx.javafxplugin") version "0.0.7"
}

Then to add the JavaFX modules you need, you would use:

javafx {
    // will pull in transitive modules
    modules("javafx.controls", "javafx.fxml") // replace with what you modules need

    // another option is to use:
    // modules = listOf("javafx.controls", "javafx.fxml")

    version = "12.0.1" // or whatever version you're using
}

repositories {
    mavenCentral() // I believe jcenter() should work as well
}

The above will pull in the javafx.base, javafx.graphics, javafx.controls, and javafx.fxml modules for the operating system the Gradle daemon is running on. It adds them to the implementation configuration. Don't manually declare any JavaFX dependencies.

Note: The org.openjfx.javafxplugin plugin also applies the com.google.osdetector and org.javamodularity.moduleplugin plugins; at least, it does in version 0.0.7.

The rest of your build file will look something like:

java {
    // replace with the Java version you're using
    sourceCompatibility = JavaVersion.VERSION_11
    targetCompatibility = JavaVersion.VERSION_11
}

application {
    mainClassName = /* your main class */
}

dependencies {
    // add your other dependencies
}

tasks {
    test {
        useTestNG()
    }
}

A good starting resource for the Kotlin DSL is the Gradle Kotlin DSL Primer page. If you're new to Kotlin, I suggest reading the reference documentation.
