package javafx.scene.control not found in Fedora 29

edit

I'm trying to build this code

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.stage.Stage;

public class ButtonExperiment extends Application  {

    @Override
    public void start(Stage primaryStage) throws Exception {
        primaryStage.setTitle("HBox Experiment 1");

        Button button = new Button("My Button");

        Scene scene = new Scene(button, 200, 100);
        primaryStage.setScene(scene);
        primaryStage.show();

    }

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

but I get this error:

package javafx.scene.control does not exist

I'm using openjava 8
