JavaFX-Gradle-Plugin

Using javafx-gradle-plugin enhances your build-script with javapackager-power. No more using Apache Ant-calls, because this gradle-plugin wraps all calls and introduces workarounds and fixes for not-yet-fixed JDK-bugs. This gradle-plugin is a convenient-wrapper for the javapackger, so you have to visit the official documentation to know about the requirements on each operating-system.

Using OpenJDK? Please make sure you have OpenJFX installed too, as the required JavaFX-parts are separated.

Using Maven? Not problem, just switch to the github-project of the javafx-maven-plugin.

Why does this gradle-plugin exist?

In the need of some equivalent of the javafx-maven-plugin just for gradle, this project was born. A lot of you might have used the javafx-gradle-plugin from Danno Ferrin, but he decided to not continue that project.

Requirements

  • Gradle 2.10 and above (works on Gradle 3 too)
  • Java Developer Kit 8 with at least Update 40

OS-specific requirements

  • (Windows) EXE installers: Inno Setup
  • (Windows) MSI installers: WiX (at least version 3.7)
  • (Linux) DEB installers: dpkg-deb
  • (Linux) RPM installers: rpmbuild
  • (Mac) DMG installers: hdiutil
  • (Mac) PKG installers: pkgbuild

Example build.gradle

Please adjust your parameters accordingly:

buildscript {
    dependencies {
        classpath group: 'de.dynamicfiles.projects.gradle.plugins', name: 'javafx-gradle-plugin', version: '8.8.2'
    }
    
    repositories {
        mavenLocal()
        mavenCentral()
    }
}

apply plugin: 'java'

repositories {
    mavenLocal()
    mavenCentral()
}

dependencies{
    // this dependency is only required when using UserJvmOptionsService
    // when using Oracle JDK
    // compile files("${System.properties['java.home']}/../lib/packager.jar")

Minimal setup of build.gradle

buildscript {
    dependencies {
        classpath group: 'de.dynamicfiles.projects.gradle.plugins', name: 'javafx-gradle-plugin', version: '8.8.2'
    }
    repositories {
        mavenLocal()
        mavenCentral()

    }
}
apply plugin: 'java'

repositories {
    mavenLocal()
    mavenCentral()
}

apply plugin: 'javafx-gradle-plugin'


jfx {
    // minimal requirement for jfxJar-task
    mainClass = 'full.qualified.nameOf.TheMainClass'
    
    // minimal requirement for jfxNative-task
    vendor = 'YourName'
}

Customize Icons

To customize the icons used in a native bundle, you have to provide the icons for the appropriate bundle. The icons must follow the file name convention in order to get picked up.

Tip: Set the verbose setting to true, to log which files are picked up from your deploy directory.

macOS

Icon location: src/main/deploy/package/macosx

In macOS you can provide up to three different icons.

  • .app icon
  • volume icon
  • the background of the window, when opening the dmg volume

The icon file name is depended on your appName setting of this plugin.

Type Filename
.app icon <appName>.icns
volume icon <appName>-volume.icns
volume background <appName>-background.png

The icon sizes should follow the specified sizes. http://iconhandbook.co.uk/reference/chart/osx/

Linux

Icon location: src/main/deploy/package/linux

For Linux you can provide one icon.

The icon file name is depended on your appName setting of this plugin.

Type Filename
application icon <appName>.png

Whitespaces in the appName will be removed in order to lookup for the icon. For example a name like 'foo Bar' will lookup for a icon like 'fooBar.png'

Windows

Icon location: src/main/deploy/package/windows

For Windows you can provide two different icons.

  • application icon
  • setup icon - the icon of the installer
Type Filename
.exe icon <appName>.ico
setup exe icon <appName>-setup-icon.bmp

Gradle Tasks

  • gradle jfxJar - Create executable JavaFX-jar
  • gradle jfxNative - Create native JavaFX-bundle (will run jfxJar first)
  • gradle jfxRun - Create the JavaFX-jar and runs it like you would do using java -jar my-project-jfx.jar, adjustable using runJavaParameter/runAppParameter-parameter
  • gradle jfxGenerateKeyStore - Create a Java keystore
  • gradle jfxListBundlers - List all possible bundlers available on this system, use '--info' parameter for detailed information

Using SNAPSHOT-versions

When you report a bug and this got worked around, you might be able to have access to some -SNAPSHOT-version, please adjust your buildscript:

buildscript {
    dependencies {
        classpath group: 'de.dynamicfiles.projects.gradle.plugins', name: 'javafx-gradle-plugin', version: '8.8.3-SNAPSHOT'
    }
    repositories {
        mavenLocal()
        mavenCentral()
        maven { url "https://oss.sonatype.org/content/repositories/snapshots" }

    }
}
