我正在学习自动化，我的java代码中有一个例外。使用Intellij IDEA

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

    DesiredCapabilities caps = new DesiredCapabilities();
    caps.setCapability("deviceName", "84B7N16401000731");
    caps.setCapability("platformName", "Android");
    caps.setCapability("app", "C:\\Appium\\node_modules\\appium\\build\\unlock_apk\\unlock_apk-debug.apk");
    Thread.sleep(5000);
 AndroidDriver driver = new AndroidDriver<MobileElement>(new URL("http://0.0.0.0:4723/wd/hub"), caps);

    driver.findElementByAndroidUIAutomator("new UiSelector().description(\"Apps\")").click();
    driver.findElementByAndroidUIAutomator("new UiSelector().text(\"Speech Morphing\")").click();

    driver.quit();
}

还有一条例外消息
