I assume I have the library jfoenix Why it cannot find it ?I have this project in javafx that I used to run and it would work perfectly. And then I wanted to add JFoenix. I had some hard time trying to make it work. and I wanted to test it so I added one JFXtextfield and I got this error

Exception running application application.Main

This is my main code 

package application;

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.stage.Stage;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.layout.BorderPane;


public class Main extends Application {
    @Override
    public void start(Stage primaryStage) {
        try {
            Parent root = FXMLLoader.load(getClass().getResource("main1.fxml"));
            Scene scene = new Scene(root,952,600);
            scene.getStylesheets().add(getClass().getResource("application.css").toExternalForm());
            primaryStage.setScene(scene);
            primaryStage.show();
        } catch(Exception e) {
            e.printStackTrace();
        }
    }

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

I did import the libraries jfoenix to my javafx code and to the scene builder. I would very much appreciate your help. it's very much needed at this time.

the second error

  • Make sure you are using a version of JFoenix compatible with the JDK you are running on. The JavaFX 8 version of JFoenix will not work with JavaFX 9 or later. – James_D May 20 '20 at 00:20
  • Thank you so much for replying. I checked now. I used to have both jfoenix 9 and 8 . i removed the latter. and I got the second error – sarah8909 May 20 '20 at 00:29
  • Not sure? Looks like it’s not finding the library at all now. – James_D May 20 '20 at 00:30
  • I'm going to put a screenshot of what I have in the library of this porject – sarah8909 May 20 '20 at 00:36
  • @James_D Is there something that I'm missing. I am really new with javafx and jfoenix – sarah8909 May 20 '20 at 00:39
  • Dont think jfoenix is a module hence belongs on the classpath not the module path not sure if that is an issue at all... just saying – Alex May 20 '20 at 18:13
  • Maybe the package was moved in the new jfoenix version – Alex May 20 '20 at 18:14
  • @Alex Thanks that helped. It worked after i placed jfoenix in the classpath. Thank you so much ! – sarah8909 May 22 '20 at 15:08
