Building a Javafx Application Using Gradle

Here is my example project with OpenJDK 12, JavaFX 12 and Gradle 5.4. It uses the JavaFX Gradle plugin.

• Opens a JavaFX window with the title "Hello World!"
• Able to build a working runnable distribution zip file (Windows to be tested)
• Able to open and run in IntelliJ without additional configuration
• Able to run from the command line

I hope somebody finds the Github project useful. Feel free to clone it. It is licensed with the Unlicense.

Peter Ledbrook's solution works, but just in case someone wants a solution that doesn't rely on external bintray links, I found one while waiting for an answer:

1) Built the JavaFX plugin from source
2) Put it in the project's libs directory
3) Applied it like this:

buildscript {
    repositories {
        flatDir dirs: "../libs"
    }
    dependencies {
        classpath "org.bitbucket.shemnon.javafxplugin:gradle-javafx-plugin:0.5.0-SNAPSHOT"
        classpath files("${System.properties['java.home']}/../lib/ant-javafx.jar")
    }
}

if (!project.plugins.findPlugin(org.bitbucket.shemnon.javafxplugin.JavaFXPlugin)) {
    project.apply(plugin: org.bitbucket.shemnon.javafxplugin.JavaFXPlugin)
}

Note that including ant-javafx in the classpath is needed due to a bug in the plugin itself (if I understand correctly)

The official gradle plugin for javafx is at .

I have successfully used this plugin from INtelliJ IDEA CE with following to illustrate my build.gradle file:

plugins {
    id 'java'
    id 'application'
    id 'maven'
    id 'maven-publish'
    id 'org.openjfx.javafxplugin' version '0.0.8'
}

javafx {
    // Points to JDK and its JavaFX libraries, also declares target runtime JDK
//    javaRuntime = '/Library/Java/JavaVirtualMachines/jdk1.7.0_40.jdk'

    version = '13' // Specify javafx sdk version
    modules = [ 'javafx.controls', 'javafx.fxml', 'javafx.swing', 'javafx.media', 'javafx.graphics']
    sdk = System.getenv('JAVAFX_HOME')
    if (sdk == null || sdk.isBlank()) {
        throw new InvalidUserDataException("JAVAFX_HOME environment variable is not set. It must be set to root folder where JAVAFX SDK is located")
    }
    application {
        def javafxHome = System.getenv('JAVAFX_HOME')
        mainClassName = 'com.foo.FooApp'
        applicationName = 'foo-app'
        applicationDefaultJvmArgs = [
            "--module-path=${javafxHome}" + File.separator + 'lib',
            '--add-modules=javafx.controls,javafx.swing,javafx.media,javafx.graphics']
        println("applicationDefaultJvmArgs:" + applicationDefaultJvmArgs)
    }
}

dependencies {
  ... ommitted ...
}

I would use the gradle init command as:

thufir@dur:~/NetBeansProjects$ 
thufir@dur:~/NetBeansProjects$ git clone :THUFIR/javaFX.git

here I've first cloned an empty repository (except for the license and readme) from github first, then initialized with gradle. Note that it's of type java-application and is using kotlin for the dsl; those can be omittied or changed to, for example, --type java-library.
