My program is running fine, but when trying to export it to a jar, I cant run the jar. I tested it by running mvn clean javafx:run which resulted in the following:

error message:

[ERROR] Failed to execute goal org.openjfx:javafx-maven-plugin:0.0.5:run (default-cli) on project myproject: Error: JavaFX runtime components are missing, and are required to run this application -> [Help 1]

This error occurs because the JavaFX runtime components are not included in the jar file. When you run your program using mvn clean javafx:run, Maven uses the javafx-maven-plugin to automatically download and include the necessary JavaFX dependencies for running the application.

However, when you try to run the jar file, it does not have access to these dependencies, resulting in the error message.

To fix this issue, you need to configure Maven to include the JavaFX dependencies in the jar file. Here's how you can do it:

  1. Add the following plugin configuration to your pom.xml file:
<build>
    <plugins>
        ...
        <plugin>
            <groupId>org.openjfx</groupId>
            <artifactId>javafx-maven-plugin</artifactId>
            <version>0.0.5</version>
            <configuration>
                <mainClass>com.example.MainClass</mainClass> <!-- Replace com.example.MainClass with your main class -->
                <options>
                    <option>--add-modules</option>
                    <option>javafx.controls,javafx.fxml</option>
                </options>
            </configuration>
        </plugin>
        ...
    </plugins>
</build>

  1. Run mvn clean package instead of mvn clean javafx:run. This will create a jar file with all the necessary dependencies included.

  2. You can now run your jar file using java -jar target/myproject.jar.

Make sure to replace com.example.MainClass with the fully qualified name of your main class.

By following these steps, you should be able to create a jar file that includes the JavaFX dependencies and can be run successfully.
