线程“JavaFX Application Thread”中的异常java.lang.NoClassDefFoundError：javafx / scene / control / ButtonBar

Question

我是JavaFx的新手，我了解到我可以使用controlsfx创建通知。但是，在包含并运行通知代码之后，我得到了一个未找到类的异常，我不知道如何处理它，因为我在研究时没有得到任何网络帮助。我使用的是JDK jdk1.8.0_20，Netbeans 8.0.2和controlsfx 8.40.14。以下是我创建通知的代码

Platform.runLater(() -> { 
    Notifications notifications = Notifications.create().title("Verification successful").text("User has been verified").graphic(null).hideAfter(Duration.seconds(2)).position(Pos.TOP_RIGHT);
                                                                    notifications.show();
});

这是个例外

我下载了jdk1.8.0_181，因为我使用Netbeans，我在Netbeans.conf文件中更改了netbeans_jdkhome以使用它，现在工作正常
