JavaFX 14 how can I export a package that is not exported?

I'm working on Netbeans 12 maven JavaFX 14.0.1 application.

The application is something like a theme viewer loading css files.

I want to capture Warnings (Errors) of the css 'StyleManager' so I can warn the user as it was proposed on this solution

    StyleManager.errorsProperty().addListener((ListChangeListener<? super CssError>) c -> {
      while (c.next()) {
        for (CssError error : c.getAddedSubList()) {
          // maybe you want to check for specific errors here
          System.out.println(error.getMessage());
        }
      }
    });

The problem is that com.sun.javafx.css.StyleManager is not exported so I get the error:

(package com.sun.javafx.css is declared in module javafx.graphics, which does not export it to module com.johntor.app)

I tried adding

--add-exports javafx.graphics/com.sun.javafx.css=com.johntor.app

without any luck!

Before this the application was working fine!!!

Any Ideas/Suggestions are more than welcome

EDIT: I included my pom file:

Thank you in advance,

Here is my pom that works for a very simple javafx maven project.

</options>
</configuration>
</plugin>
</plugins>
</build>
</project>

I was able to build with mvn package and run the project with mvn javafx:run.

My module is named 'mavenfxied' and my package is 'example'.

Here is the final pom that worked. And I include it to save somebody else.

I had a bad impression that --add-exports enables exporting on both compile and run time so gives greater freedom than --add-opens. But --add-opens enables deep reflection so it must be used here.

        <plugin>
<groupId>org.openjfx</groupId>
<artifactId>javafx-maven-plugin</artifactId>
<version>0.0.4</version>
<configuration>
<mainClass>com.johntor.app.App</mainClass>
<options>
<option>--add-opens</option>
<option>javafx.controls/javafx.scene.control=com.johntor.app</option>
<option>--add-opens</option>
<option>javafx.graphics/com.sun.javafx.css=com.johntor.app</option>                    
</options>
</configuration>
