java - 为什么在 Java 中会出现 NoSuchFieldError 异常？

Question

我正在尝试使用 Eclipse 内部浏览器显示任何网站。

这是我正在尝试的代码:

public class WebTest {

    public static void main(String[] args) {
        NativeInterface.open();
        SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                JFrame frame = new JFrame("YouTube Viewer");
                frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
                frame.getContentPane().add(getBrowserPanel(),
                        BorderLayout.CENTER);
                frame.setSize(800, 600);
                frame.setLocationByPlatform(true);
                frame.setVisible(true);
            }
        });
        NativeInterface.runEventPump();
        // don't forget to properly close native components
        Runtime.getRuntime().addShutdownHook(new Thread(new Runnable() {
            @Override
            public void run() {
                NativeInterface.close();
            }
        }));
    }

    public static JPanel getBrowserPanel() {
        JPanel webBrowserPanel = new JPanel(new BorderLayout());
        JWebBrowser webBrowser = new JWebBrowser();
        webBrowserPanel.add(webBrowser, BorderLayout.CENTER);
        webBrowser.setBarsVisible(false);
        webBrowser.navigate("https://www.youtube.com/v/b-Cr0EWwaTk?fs=1");
        return webBrowserPanel;
    }
}

但是，当我尝试运行它时，出现以下异常:

Exception in thread "main" java.lang.NoSuchFieldError: DEPENDENCIES_CHECKVERSIONS

at WebTest.main(WebTest.java:14)

所以我的依赖项显然有问题......但我不知道如何解决这个问题，我已经包含了所有必要的 jar :

有什么想法吗？
