Packaging with JavaFX

[dresch86]

I have been looking for an example of how to package JavaFX with this plugin. I added the following to the gradle.build

task packageMyApp(type: io.github.fvarrui.javapackager.gradle.PackageTask, dependsOn: build) {
    // mandatory
    mainClass = 'org.ose.scheduler.MyAppLauncher'

    // optional
    bundleJre = true
    generateInstaller = true
    administratorRequired = false

    additionalModulePaths = [file("$System.env.PATH_TO_FX/lib")]
    additionalModules = ['javafx.base', 'javafx.controls', 'javafx.graphics', 'javafx.fxml']
}

But it looks like the bundled JRE is missing all the JavaFX .dll's. When I copy them manually, the app.exe works fine. Without copying the ,dll's, the executable does not work. I am running on Windows.

Hey there, I fell into this pit too! At issue is that JavaFX jars are platform-specific.

Don't know with Gradle, but with maven, I've solved it with profiles and classifiers. Here is an example:

<!-- Set up profiles -->
  <profiles>
	  <profile>
	  	<id>win</id>
		<activation>
		  <os>
	    	<family>windows</family>
		  </os>	
		</activation> 
		<properties>
		  <os.label>win</os.label>
		  <os.libs>libs</os.libs>
		  <javafx.platform>win</javafx.platform>
	    </properties>
	  </profile>
	  <profile>
	  	<id>mac</id>
		<activation>
		  <os>
	    	<family>mac</family>
		  </os>	
		</activation> 
		<properties>
		  <os.label>mac</os.label>
		  <os.libs>Java/libs</os.libs>
		  <javafx.platform>mac</javafx.platform>
	    </properties>
	  </profile>
	  <profile>
	  	<id>linux</id>
		<activation>
		  <os>
	    	<family>unix</family>
	    	<name>Linux</name>
		  </os>	
		</activation> 
		<properties>
		  <os.label>linux</os.label>
		  <os.libs>libs</os.libs>
		  <javafx.platform>linux</javafx.platform>
	    </properties>
	  </profile>
  </profiles>

<!-- Java FX Dependencies with classifiers -->

<dependencies>
   <dependency>
    <groupId>org.openjfx</groupId>
    <artifactId>javafx-base</artifactId>
    <version>${jfx.version}</version>
    <classifier>${os.label}</classifier>
  </dependency>
   <dependency>
    <groupId>org.openjfx</groupId>
    <artifactId>javafx-fxml</artifactId>
    <version>${jfx.version}</version>
    <classifier>${os.label}</classifier>
  </dependency>
   <dependency>
    <groupId>org.openjfx</groupId>
    <artifactId>javafx-graphics</artifactId>
    <version>${jfx.version}</version>
    <classifier>${os.label}</classifier>
  </dependency>
</dependencies>

Hope this helps!

What versions of java and javafx are used? Maybe you can refer to the following configuration.

java version: 17
javafx verison: 17.0.2

plugins {
    kotlin("jvm") version "1.6.21"
    id("application")
    id("org.openjfx.javafxplugin").version("0.0.10")
}
buildscript{
    repositories {
        mavenCentral()
        gradlePluginPortal()
    }
    dependencies {
        classpath("io.github.fvarrui:javapackager:1.7.5")
    }
}
apply(plugin = "io.github.fvarrui.javapackager.plugin")
tasks.register("trlh",io.github.fvarrui.javapackager.gradle.PackageTask::class.java){
    mainClass = "your mainClass"
    displayName = "your displayName "
    appName = "your appName"
    isBundleJre = true
    isCustomizedJre = false
    isCopyDependencies = true
    isGenerateInstaller = true
    platform = io.github.fvarrui.javapackager.model.Platform.auto
    // vm param
    vmArgs = ArrayList<String?>().apply {
        this.add("-Xms256M")
    }
    // SSL 
//    if(additionalModules == null){
//        additionalModules = ArrayList<String>()
//    }
//    additionalModules.apply {
//        this.add("jdk.crypto.ec")
//    }

    winConfig(null).apply {
        this.headerType = io.github.fvarrui.javapackager.model.HeaderType.console
        isGenerateInstaller = true
        isGenerateSetup = true
        isGenerateMsi = false
        isGenerateMsm = false
        this.isDisableDirPage = false
        this.isDisableFinishedPage = false
        this.isDisableRunAfterInstall = false
    }

    linuxConfig(null).apply {
        isGenerateInstaller = true
        isGenerateDeb = true
        isGenerateAppImage = false
        isGenerateRpm = false
    }
}

javafx{
    version = "17.0.2"
    modules("javafx.base","javafx.controls","javafx.web")
}

@ilacc1 @dresch86 You can try this demo project https://github.com/lhDream/demo/tree/main/java17Demo/javafxDemo

I am using Java 20.0.2 and the matching JavaFX version. I found out what my problem was. For some reason, even though I added the Gradle dependencies, the mods weren't getting included. I fixed that by manually downloading the jmods, setting the path as an environment variable, and including them like this....

additionalModulePaths = [file("$System.env.PATH_TO_FX_MODS")]

Doing it this way adds some work to my CircleCI build, but it works! The repo is here but still undergoing development.
