线程＆＃34; main＆＃34;中的例外情况java.lang.NoClassDefFoundError：javax / websocket / DeploymentException

Question

我正在尝试执行此程序：

public class IosSettings {

    public static AppiumDriver driver;

    public static void main(String[] args) throws MalformedURLException, InterruptedException{

        DesiredCapabilities capabilities = new DesiredCapabilities();
        capabilities.setCapability("deviceName", "sameer's iphone");
        capabilities.setCapability("platformName", "iOS");
        capabilities.setCapability("platformVersion", "11.4");
        capabilities.setCapability("app", "settings");

        driver = new IOSDriver(new URL("https://0.0.0.0:4723/wd/hub"), capabilities);
        driver.manage().timeouts().implicitlyWait(80, TimeUnit.SECONDS);

    }

}

但是，我收到了这个错误：
