Проблема компилирования maven в javafx проекте

В общем, при компиляции с помощью maven (mvn clean compile exec:java) выскакивает исключение + как только использую FXMLLoader : Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.2:java (default-cli) on project libraryManagementSystem: An exception occured while executing the Java class. null Если его убрать из кода - всё прекрасно работает. По поводу этой ошибки глянул всё - не помогло, может мой случай какой-то отдельный. Заранее благодарю за любой фидбэк.

Main class(App)

package org.example;

import ...;

public class App extends Application {
    public static void main( String[] args ) {
        launch();
    }

    @Override
    public void start(Stage stage) throws Exception {
        Parent root = FXMLLoader.load(getClass().getResource("/resources/loginStage.fxml"));
        Scene scene = new Scene(root);
        stage.setScene(scene);
        stage.setTitle("just a scene");
        stage.show();
    }
}
