Running Jar file application returns NullPointerException with JavaFX 8

Question

everybody !

I'm having some hard time trying to run my JavaFX Application. When I run it inside Eclipse, it works fine, but attempting to run it by means of the jar file, I get the following message error. Am I missing something ?

C:\Users\antonio.a\workspace_cusomization\Checklist\build\deploy\Checklist.jar
java.lang.NullPointerException: Location is required.

Edited:

The package hierarchy:

sidia.org.br
sidia.org.br.controller
sidia.org.br.view

MainView.fxml file is inside sidia.org.br.view

and Main.class is inside sidia.org.br

public class Main extends Application {

    @Override
    public void start(Stage primaryStage) {

        try {

            AnchorPane root = (AnchorPane)FXMLLoader.load(getClass().getResource("./view/MainView.fxml"));
            Scene scene = new Scene(root, 900, 650);
            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);
    }
}
