How to deploy JavaFX 15 Code to JAR with Java 15

I have a Problem with Deploying my JavaFX Project to a .jar or .exe File to easily execute it (and achive the Project Requirements).
I am trying to get it to work as a .jar File because I think thats the easier Way to go but maybe I am wrong so it would be awesome if you could help me solve this Problem.
I already tried using the Artifacts from Intellij but this is not working. I get an Errormessage which says "Error: JavaFX runtime components are missing, and are required to run this application".
Then I tried using another Way which I found on the Internet: https://github.com/openjfx/samples/tree/master/CommandLine/Non-modular/CLI but this is resulting in exactly the same message when trying to package it to a .jar File.
All of the above I tried on my existing Project and on a completely new one with nothing inside except the prewirtten Stuff from Intellij when you create a new JavaFX Project.
My Project exists of nothing like Maven or Gradle, I just have a basic JavaFX Project (JavaFX 15 and Java 15) with one additional Library: org.json:json version 20201115
I hope these Informations are enough for you to understand my Problem and hopefully help me, but if not just ask for what you need and I will do my best to provide it to you.
Thanks for helping :)
Best Regards
Maxi

this might not concern your particular situation, but maybe it can give you a hint.
Short explanation
I solved the "Error initializing QuantumRenderer: no suitable pipeline found"
by manually including library-files to the fat JAR and adding them to the classpath, which is used for execution, with the assistance of Gradle.
I included:
the required openJFX-JARs from my system's openJFX installation
the accompanying C++ libraries like the renderer libprism_sw.so (*.so on linux, *.dll on Windows)
The hint for the libs came from JavaFX on Linux is showing a "Graphics Device initialization failed for : es2, sw"
"The problem can be in your old JRE version, which doesn't contain all the necessary libraries, such as libprism_es2.so or libglass.so, which should be located in /usr/lib/jvm/java-8-openjdk-amd64/jre/lib/amd64."
...
"Download latest JRE from the official Oracle website and copy lib folder to your current JRE location. That should be enough."
Full explanation
"Error initializing QuantumRenderer" Problem
I had a similar problem with a fat JAR filled with several JFX-example classes from the code for a Java-book. The project uses Gradle for build management and runs the JFX-examples using the fat JAR (build/libs/Java-Profi-all.jar).
The "Error initializing QuantumRenderer" appeared when I tried to execute a simple HelloWorld example for JFX (FirstJavaFxExample) on the command line using bin/java of my current JRE without using Gradle. I almost solved the issue with the hints on JavaFX on Linux is showing a "Graphics Device initialization failed for : es2, sw" , but I got stuck on the same error in the end. Even if I added the required openJFX-JARs and accompanying C++ libraries in the fat JAR and to the classpath via "-cp ...:projectdir/build/requiredLibs".
Used command:
/usr/lib64/jvm/java-1.8.0-openjdk-1.8.0/bin/java -Dfile.encoding=UTF-8 -Duser.country=US -Duser.language=en -Duser.variant -Dprism.verbose=true -cp projectdir/build/libs/Java-Profi-all.jar:projectdir/build/requiredLibs ch14_javafx.basics.FirstJavaFxExample

Found solutions with Gradle
I found two solutions, only the first using a fat JAR:
quick-n-dirty solution with pseudo-launcher class using fat JAR
long term solution with Jmods/modularization (not working with fat JAR for me)
I couln't make the long term solution work with the fat JAR Java-Profi-all.jar. Anyway you can find further infos about the modular solution here:
"Make your app modular" on https://edencoding.com/runtime-components-error/
How to fix "Error: JavaFX runtime components are missing, and are required to run this application" : "In short, you have to compile / run by adding the javafx modules in, either as options passed on the command line, or using a modular project."
Gradle solution without using the Gradle-plugin org.openjfx.javafxplugin
: Task 'run' causes: org.joor.ReflectException: java.lang.NoSuchFieldException: javaExecHandleBuilder - Gluon Mobile Project
quick-n-dirty solution with fat JAR
In order to execute the class ch14_javafx.basics.FirstJavaFxExample with Gradle I wrote the class JfxEdencodingDirtyFixLauncher in the same package:
package ch14_javafx.basics;
public class JfxEdencodingDirtyFixLauncher {
public static void main(String[] args){
FirstJavaFxExample.main(args);
}
}
Additionally I made the following modifications on build.gradle:
A) Ensuring the fitting JRE-version for the used openjfx-version.
sourceCompatibility=1.11
targetCompatibility=1.11
B) manually including the openjfx-JARs and C++ libraries (*.so) to the build-configuration (due to my linux installation):
dependencies
{
...
compile fileTree('/usr/local/manuell/javafx-sdk-11.0.2/lib/') { include '*.jar' }
runtime fileTree('/usr/local/manuell/javafx-sdk-11.0.2/lib/') { include '*' } // also inlcude *.so files for JNI-access
...
The gradle.build-script later copies these *.jar and *.so files to a the subfolder requiredLibs and adds them to the classpath when building the JAR jar:
...
task copyRequiredLibs(type: Copy) {
from configurations.runtime
into "$buildDir/libs/requiredLibs"
}
jar {
dependsOn copyRequiredLibs
baseName = "Java-Profi-all"
manifest {
attributes(
"Created-By" : "Michael Inden",
"Specification-Title" : "Java-Profi",
"Specification-Version" : "3",
"Specification-Vendor" : "Michael Inden",
"Implementation-Title" : "Java-Profi",
"Implementation-Version" : "3",
"Implementation-Vendor" : "Michael Inden",
"Class-Path": configurations.runtime.collect { "requiredLibs/" + it.getName() }.join(' '))
}
// JAR-Dateien mit aufnehmen, dann kann man diese bei Bedarf separat entpacken
into('requiredLibs') {
FileCollection collection = files("$buildDir/libs/requiredLibs")
from { collection.collect { it } }
}
...
For execution of the fat JAR with custom gradle tasks, I added a task definition to the predefined appTasks.txt file:
task JfxEdencodingDirtyFixLauncher (dependsOn: jar, group: 'Java_Profi_Chapter_14') {doLast { executeClass("ch14_javafx.basics.JfxEdencodingDirtyFixLauncher") }}
This task can then be executed using the fat JAR with this command:
gradle JfxEdencodingDirtyFixLauncher

Running .jar with CLI

I am trying to export a runnable .jar file however I am faced with the following problems:
"VM arguments will not be part of the runnable JAR. Arguments can be passed on the command line when launching the JAR"
I ignored the warning and hit finish to create the runnable .jar file. When I double click it doesn't work.
I ran the following code in my command line:
**java -jar C:\path\file.jar --module-path "C:\pathtofxsdk11\lib" --add-modules javafx.controls,javafx.fxml,javafx.base,javafx.swing, javafx.graphics**

I need help with creating the executable Jar.

The options you provided in the command line are in the wrong order. Anything supplied after the name of the jar file (or the main class, if you are not using the -jar option) will be interpreted as an argument to your Java application (as opposed to an argument to the JVM), and passed to the string array in the
public static void main(String[])
method in the main class.
Thus you should use
java --module-path "C:\pathtofxsdk11\lib" --add-modules javafx.controls,javafx.fxml,javafx.base,javafx.swing,javafx.graphics -jar C:\path\file.jar
Note that this doesn't mean the jar file can be used as an "executable jar" that can simply be run on any system, because the JavaFX runtime is not included in the standard Java runtime from version 11 onwards. Instead, you can use the jpackage tool, which is included in JDK 14, to create a native installer bundle. This bundle will include a Java runtime, which you can configure to include JavaFX.
You should first download and unzip the modular version of JavaFX (the "jmods") from here.
Then your jpackage command looks something like the following:
jpackage --module-path "C:\pathtofxmods" --add-modules javafx.controls,javafx.fxml,javafx.swing --input "C:\path" --main-jar file.jar --type exe --name MyApp --dest "C:\path\to\generated\executable"
where C:\pathtofxmods is the library you unzipped in the previous step: it should include a collection of *.jmod files. This will generate an .exe file in C:\path\to\generated\executable which will install the application on a windows system. You can distribute this - note the end users do not even need a JRE, as this will bundle a JRE with the package.
You can also run jlink independently to create the JRE (with JavaFX) that is bundled with the application. See a full tutorial and the full tool documentation.

How to solve "Graphics Device initialization failed for : d3d, sw" when running a java Jar file with JavaFx

Good Afternoon everyone.
I'm having a problem when I try to run my Java Code as a Runnable Jar file. I'm using Eclipse and I created a normal Java Project. I included the JavaFX jars as a User Libary. The Program runs without a problem when I start it with the IDE. To create the Jar file I use the the build in Export of a Java Project in the Runnable Jar file.
When I check "Extract required libaries into generated JAR" and run it, I get this Error Message:
Error: JavaFX runtime components are missing, and are required to run this application
When I check "Package required libaries into generated JAR" and run it, I get this Error Message:

Does anyone know, why I cannot run the JAR but in the IDE it runs normally?
I installed JavaFX following the Documentation here https://openjfx.io/openjfx-docs/ .

I found a solution to my Problem. When I Export the Libaries into the Generated Jar I got the Error that the JavaFX Runtime components are missing. I now remembered that I got the same Error in Eclipse before although there was no Error in the Code and I used JavaFX elements. But to get it up and running I had to add VM Arguments. So I only had to write this in the command promt when I wanted to run the program.
Assuming you already are in the directory of your build Jar file:
java --module-path "C:\Path\to\javafx-sdk-13.0.2\lib" --add-modules javafx.controls,javafx.fxml -jar YourJar.jar
It's working now for me. Hope it will help others too.
Best Wishes

Check your built jar file manifest file to see what are its dependencies. There will be an variable called Class-path:
U can do this by right clicking on the jar file and opening with winrar or normal explorer META.INF
If they all begin with libs/ then create an libs folder where your built jar file is located and copy all javafx specified jar files into that folder and then execute

Run JavaFX with Visual Studio Code Remote Extension

I'm already trying for a few hours to run a JavaFX application with the help of the Visual Studio Remote Development extension within a Docker Container.
I want to forward the graphic of the application with the help of X11. I already integrated the required packages for X11 in the container, set the DISPLAY environment variable and mounted the X11 socket in the container (/tmp/.X11-unix/).
Unfortunately, it won't work like that... Whenever I try to run the application, I get the following error message:

Exception in thread "main" java.lang.RuntimeException: No toolkit found
I'm using openjdk:11 as base image for the docker container and installed the following packages inside of it:
openjfx
libx11-dev
libxext-dev
libxrender-dev
libxtst-dev
I previously already tried to run IntelliJ within a Docker container, which is working fine. The GUI gets forwarded to my Display and also JavaFX applications are working fine in there.
I would appreciate any help on this matter. Maybe I oversee something.
EDIT:
I think I found the problem. It seems like OpenJDK:11 and OpenJFX do not work correctly, even though I followed tons of tutorials...
So what I did now is that I exported the JDK, which comes with IntelliJ IDEA and mounted it into the container, which gets created of VS Code. After compiling the .java file with the mounted compiler and executing it, it worked flawlessly.
So now my only problem is, that I need a working setup within VS Code to get JavaFX applications working -> so a proper OpenJDK and OpenJFX configuration.

Finally, I was able to fix the problem. So the solution was:
I created an own Dockerfile, where I took the openjdk:12 image as base and copied the JavaFX libraries (which I got from here: https://gluonhq.com/products/javafx/) into the container. Additionally, I added all required packages for X11 (mentioned above).
In VS Code, after the container has been started, I simply had to add the libs to the "Referenced Libraries".
Afterwards, I had to adjust the launch.json and added the following vmArgs:
"vmArgs": "--module-path <Path-to-FX-Folder> --add-modules javafx.controls"
Now when I run the application, the window is going to be created and shown on my DISPLAY.

Build step 'Invoke Gradle script' changed build result to FAILURE
Build step 'Invoke Gradle script' marked build as failure
Finished: FAILURE
I changed the field "Root Build script" to C:\\Workspace\\SSD\\build.gradle , still doesn't work.
When I build my codes using gradle (without Jenkins), it works fine.
Any clue maybe?
Thank you.

From the documentation at https://wiki.jenkins.io/display/JENKINS/Gradle+Plugin, and from the error it gives you, it expects the folder of the build script in that configuration option, not the full path to the script itself. Change it to C:\Workspace\SSD and I expect it will work.
