How to export JavaFX 11 Project into Jar?

I spent hours googling today most solutions are out of date. I use eclipse on Window the project complies, but I am unable to make it a standalone application without:

java --module-path C:\javafx-sdk-11.0.2\lib\  --add-modules javafx.controls,javafx.fxml,javafx.graphics,javafx.web -jar Jar.jar

What are the ways I can export JavaFX 11 Projects into an executable jar without the need to link it to javafx-sdk-11.0.2 after export?

Thanks.

You may build this project with Maven from your IDE, including necessary dependencies:

<dependency>
    <groupId>org.openjfx</groupId>
    <artifactId>javafx-controls</artifactId>
    <version>11.0.2</version>
</dependency>
<dependency>
    <groupId>org.openjfx</groupId>
    <artifactId>javafx-fxml</artifactId>
    <version>11.0.2</version>
</dependency>
<dependency>
    <groupId>org.openjfx</groupId>
    <artifactId>javafx-graphics</artifactId>
    <version>11.0.2</version>
</dependency>
<dependency>
    <groupId>org.openjfx</groupId>
    <artifactId>javafx-web</artifactId>
    <version>11.0.2</version>
</dependency>

Build your project with Maven and use that kind of pom.xml:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
         http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>tld.group</groupId>

    <version>1.0.0-SNAPSHOT</version>
    <packaging>jar</packaging>

You have to provide two application classes.

The Javafx one:

public class YourJavaFxAppMainClass extends javafx.application.Application {

    @Override
    public void start(Stage stage) throws IOException {
        // ...
    }

    public static void main(String[] args) {
        launch();
    }
    // ...
}

The other which is used to run your program from your IDE (for instance IntelliJ):

public class YourMainClass {

    public static void main(final String[] args) {
        YourJavaFxAppMainClass.main(args);
    }
}

Then you can package your jar using mvn clean package and run it with java -jar target/artifact.jar.
