将程序导出到 jar 文件时 JFXDatePicker 不起作用

如何解决将程序导出到 jar 文件时 JFXDatePicker 不起作用

我有一个应用程序，它使用来自 JFoenix 的两个 JFXDatePickers。它们在从 Eclipse 运行时完美运行，但在我将程序导出到 JAR 文件时不起作用。它们仍然返回默认设置的文本，但是当我尝试使用它选择日期时，窗口会冻结并且应用程序没有响应。

我已经搜索过 stackoverflow 和 javafx 以及 jfoenix 文档，但似乎找不到答案。有人可以帮帮我吗？这是一个学校项目。有什么建议吗？

@FXML
private JFXDatePicker startDatePicker;

@FXML
private JFXDatePicker endDatePicker;

@FXML
private void initialize() {
    this.endDatePicker.setValue(LocalDate.Now());
    this.startDatePicker.setValue(LocalDate.Now().withDayOfMonth(1));
}

非常感谢！

编辑：谢谢你的建议，斯劳。我已经通过命令行启动了它并且没有出现任何异常。发生错误的控制器类是这个：

package application;

import java.time.LocalDate;

import com.jfoenix.controls.JFXDatePicker;

import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import javafx.scene.control.Alert;
import javafx.scene.control.Button;

public class SeeAllQuotesFilterScreenController {

    @FXML
    private Button cancelButton;

    @FXML
    private Button enterButton;

    @FXML
    private JFXDatePicker startDatePicker;

    @FXML
    private JFXDatePicker endDatePicker;

    @FXML
    private void initialize() {
        this.endDatePicker.setValue(LocalDate.Now());
        this.startDatePicker.setValue(LocalDate.Now().withDayOfMonth(1));
    }

    @FXML
    void cancelButtonClicked(ActionEvent event) {
        new Alert(Alert.AlertType.informatION,"changes to a different screen on the complete application").showAndWait();
    }

    @FXML
    void enterButtonClicked(ActionEvent event) {

        new Alert(Alert.AlertType.informatION,"changes to a different screen on the complete application").showAndWait();
        
    }
}

此外，fxml：

我的主（）：

package application;

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


public class Main extends Application {
    @Override
    public void start(Stage primaryStage) {
        try {
            borderpane root = (borderpane) FXMLLoader.load(getClass().getResource("SeeAllQuotesFilterScreen.fxml"));
            Scene scene = new Scene(root,500,600);
            primaryStage.setScene(scene);
            primaryStage.show();
        } catch (Exception e) {
            e.printstacktrace();
        }
    }

    public void initialize() {

    }

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

感谢所有帮助！
