JavaFx : create jar under linux and run it under windows 10

Question

I have a simple Java FX(11.x LTS) application developed under Linux. I want to create a jar file to be executed under win 10. For this I have the following 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"

    </dependencies>
</project>

On Windows I've downloaded JavaFX SDk and put its path to PATH variable( both bin and lib folders ). I'm trying to execute it via java -jar *.jar But I get the following error :

java.lang.ClassNotFoundException: com.sun.glass.ui.win.WinPlatformFactory

What is the reason for the failure? Do I use a valid approach to deploy JavaFX app?

Check out [this answer](https://stackoverflow.com/a/52654791/6395627); it shows creating a fat jar with Maven. I believe the modules which have platform-specific code are `javafx.graphics`, `javafx.media`, and `javafx.web`. Of those that you use, you have to manually declare a dependency for each platform you want to support. So in your case I think you need to add `linux` and `win` dependencies for `javafx.graphics`. — Slaw, Jun 10 '20 at 13:44

As explained by this answer by @JoséPereda, you have to include each platform-specific dependency for certain JavaFX modules—more specifically, the ones which contain platform-specific code—in order to create a cross-platform fat jar. I believe those modules are javafx.graphics, javafx.media, and javafx.web. Of those that you use, you have to manually declare a dependency for each platform you want to support. In your case, I believe the following will be sufficient:

<dependencies>
  <dependency>
    <groupId>org.openjfx</groupId>
    <artifactId>javafx-graphics</artifactId>
    <version>${javafx.version}</version>
    <classifier>win</classifier>
  </dependency>

  <dependency>
    <groupId>org.openjfx</groupId>
    <artifactId></artifactId>
    <version>${javafx.version}</version>
    <classifier>linux</classifier>
  </dependency>

  <dependency>
    <groupId>org.openjfx</groupId>
    <artifactId>javafx-controls</artifactId>
    <version>${javafx.version}</version>
  </dependency>

  <dependency>
    <groupId>org.openjfx</groupId>
    <artifactId>javafx-fxml</artifactId>
    <version>${javafx.version}</version>
  </dependency>
</dependencies>
