Javafx加载xml文件时出错

我有一个问题,我可以加载某些xml文件,但其他人不能。

sample fxml loaded

但不是startScreen或MainView fxml文件

MainView not being able to load

调用TargetException RuntimeException:应用程序启动方法中的异常 javafx.fxml.LoadException ClassNotFoundException:view.MainView

重建程序并不能解决问题。 我看到一些网站提到一些关于资源文件没有被制作?可能是这样?如果是这样的话,有人能对它有更多的了解吗。

代码如下:

package sample;

 import javafx.application.Application;
 import javafx.fxml.FXMLLoader;
 import javafx.scene.Scene;
import javafx.scene.layout.Pane;
import javafx.stage.Stage;
import java.io.IOException;

public class Main extends Application {

private Pane startLayout, gameFrame;
private Stage primaryStage;

//
@Override
public void start(Stage primaryStage) throws Exception {
    this.primaryStage = primaryStage;
    this.primaryStage.setTitle("Ron");

    showStartScreen();
}
//

public void showStartScreen() throws IOException {

    FXMLLoader loader = new FXMLLoader();
    loader.setLocation(Main.class.getResource("/view   /mainView.fxml"));
    startLayout = loader.load();
    Scene scene = new Scene(startLayout);
    primaryStage.setScene(scene);
    primaryStage.show();


}


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

错误消息:
