Allow local JavaFX SDK

JavaFX Gradle Plugin

Simplifies working with JavaFX 11+ for gradle projects.

Getting started

To use the plugin, apply the following two steps:

1. Apply the plugin

Using the `plugins` DSL:

Groovy

plugins {
    id 'org.openjfx.javafxplugin' version '0.1.0'
}

Kotlin

plugins {
    id("org.openjfx.javafxplugin") version "0.1.0"
}

Alternatively, you can use the `buildscript` DSL:

Groovy

buildscript {
    repositories {
        maven {
            url "https://plugins.gradle.org/m2/"
        }
    }
    dependencies {
        classpath 'org.openjfx:javafx-plugin:0.1.0'
    }
}
apply plugin: 'org.openjfx.javafxplugin'

Kotlin

buildscript {
    repositories {
        maven {
            setUrl("https://plugins.gradle.org/m2/")
        }
    }
    dependencies {
        classpath("org.openjfx:javafx-plugin:0.1.0")
    }
}
apply(plugin = "org.openjfx.javafxplugin")

2. Specify JavaFX modules

Specify all the JavaFX modules that your project uses:

Groovy

javafx {
    modules = [ 'javafx.controls', 'javafx.fxml' ]
}

Kotlin

javafx {
    modules("javafx.controls", "javafx.fxml")
}

3. Specify JavaFX version

To override the default JavaFX version, a version string can be declared. This will make sure that all the modules belong to this specific version:

Groovy


javafx {
    version = '17'
    modules = [ 'javafx.controls', 'javafx.fxml' ]
}

Kotlin


javafx {
    version = "17"
    modules("javafx.controls", "javafx.fxml")
}

4. Cross-platform projects and libraries

The plugin will include JavaFX dependencies for the current platform. However, a different target platform can also be specified.

Supported targets are:

linux
linux-aarch64
win or windows
osx or mac or macos
osx-aarch64 or mac-aarch64 or macos-aarch64 (support added in JavaFX 11.0.12 LTS and JavaFX 17 GA)

Groovy


javafx {
    modules = [ 'javafx.controls', 'javafx.fxml' ]
    platform = 'mac'
}

Kotlin


javafx {
    modules("javafx.controls", "javafx.fxml")
    platform = 'mac'
}

5. Dependency scope

JavaFX application require native binaries for each platform to run. By default, the plugin will include these binaries for the target platform. Native dependencies can be avoided by declaring the dependency configuration as compileOnly.

Groovy


javafx {
    modules = [ 'javafx.controls', 'javafx.fxml' ] 
    configuration = 'compileOnly'
}

Kotlin


javafx {
    modules("javafx.controls", "javafx.fxml")
    configuration = "compileOnly"
}

Multiple configurations can also be targeted by using configurations. For example, JavaFX dependencies can be added to both implementation and testImplementation.

Groovy


javafx {
    modules = [ 'javafx.controls', 'javafx.fxml' ]
    configurations = [ 'implementation', 'testImplementation' ]
}

Kotlin


javafx {
    modules("javafx.controls", "javafx.fxml")
    configurations("implementation", "testImplementation")
}

5. Using a local JavaFX SDK

By default, JavaFX modules are retrieved from Maven Central. However, a local JavaFX SDK can be used instead, for instance in the case of a custom build of OpenJFX.

Setting a valid path to the local JavaFX SDK will take precedence:

Groovy


javafx {
    sdk = '/path/to/javafx-sdk'
    modules = [ 'javafx.controls', 'javafx.fxml' ]
}

Kotlin


javafx {
    sdk = "/path/to/javafx-sdk"
    modules("javafx.controls", "javafx.fxml")
}

Migrating from 0.0.14 to 0.1.0

Version 0.1.0 introduced several changes and improvements, including lazy dependency declaration, variant-aware dependency management, and support for Gradle's built-in JPMS functionality. In the previous version, the classpath/module path was rewritten. This is no longer the case. As a result, your past builds might be affected when you upgrade the plugin. In the next section, there are a few troubleshooting steps that might help with the transition if you encounter issues when upgrading. These examples are provided on a best-effort basis, but feel free to open an issue if you believe there's a migration scenario not covered here that should be included.

Troubleshooting

Gradle version

The plugin now requires Gradle 6.1 or higher. Consider updating your Gradle settings, wrapper, and build to a more recent version of Gradle. Additionally, updating your plugins and dependencies can help minimize issues with the plugin.

Mixed JavaFX jars

If you encounter mixed classified JavaFX jars or see errors like Error initializing QuantumRenderer: no suitable pipeline found during executing task like build, test, assemble, etc., it is likely one or more of your dependencies have published metadata that includes JavaFX dependencies with classifiers. The ideal solution is to reach out to library authors to update their JavaFX plugin and publish a patch with fixed metadata. A fallback solution to this is to exclude group: 'org.openjfx' on the dependencies causing the issue.

implementation('com.example.fx:foo:1.0.0') {
    exclude group: 'org.openjfx', module: '*'
}

Variants

If you encounter errors such as Cannot choose between the following variants of org.openjfx... it is possible that your build or another plugin is interacting with the classpath/module path in a way that "breaks" functionality provided by this plugin. In such cases, you may need to re-declare the variants yourself as described in Gradle docs on attribute matching/variants or reach out to the plugin author in an attempt to remediate the situation.

// Approach 1: Explicit Variant
// The following snippet will let you add attributes for linux and x86_64 to a configuration
configurations.someConfiguration {
    attributes {
        attribute(Usage.USAGE_ATTRIBUTE, objects.named(Usage, Usage.JAVA_RUNTIME))
        attribute(OperatingSystemFamily.OPERATING_SYSTEM_ATTRIBUTE, objects.named(OperatingSystemFamily, "linux"))
        attribute(MachineArchitecture.ARCHITECTURE_ATTRIBUTE, objects.named(MachineArchitecture, "x86-64"))
    }
}

// Approach 2: Copy existing configuration into another configuration
configurations.someConfiguration  {
    def runtimeAttributes = configurations.runtimeClasspath.attributes
    runtimeAttributes.keySet().each { key ->
        attributes.attribute(key, runtimeAttributes.getAttribute(key))
    }
}

Extra plugins

In versions 0.0.14 and below, there was a transitive dependency on org.javamodularity.moduleplugin. If your modular project stops working after updating to 0.1.0 or above, it is likely that you need to explicitly add the org.javamodularity.moduleplugin back to your build and set java.modularity.inferModulePath.set(false) to keep things working as they were. This plugin helped with transitive dependencies on legacy jars that haven't been modularized yet, but now you have to option choose which approach to take. This change should not be required for non-modular projects.

Before

plugins {
    id 'org.openjfx.javafxplugin' version '0.0.14'
}

After

plugins {
    id 'org.openjfx.javafxplugin' version '0.1.0'
    id 'org.javamodularity.moduleplugin' version '1.8.12'
}

java {
    modularity.inferModulePath.set(false)
}

Note: There are other recommended alternatives over org.javamodularity.moduleplugin for modular projects such as extra-java-module-info that would allow you to keep inferModulePath set to true by declaring missing module information from legacy jars. More details on how to accomplish can be found on the plugin's source code repository.

Dependency hierarchy

Version 0.1.0 now relies on JavaFX modules defining their transitive modules rather than flattening them. This change allows you to publish metadata declaring only the JavaFX modules you need, meaning it does not include transitive JavaFX modules as part of your published metadata.

Some plugins rely on having all modules (transitive included) declared as "top-level" modules such as the badass-runtime-plugin on non-modular projects. In this particular case, it is necessary to declare all modules to restore previous functionality from 0.0.14 and below.

Before

javafx {
    modules = ['javafx.controls']
}

After

javafx {
    modules = ['javafx.base', 'javafx.graphics', 'javafx.controls']
}

Build configuration	Configuration file	Result
Gradle with plugin	build.gradle	Build fails due to error above
Gradle without plugin (dependencies added manually)	build.gradle	Build passes
Maven with plugin	pom.xml	Build passes
