如下，升级 appium 到 1.3.4, 用下面的方法滑动屏幕失败。该如何处理？请大神指教。

public static void swipeScreen(Double startX, Double startY, Double endX,
    Double endY, Double duration, int repeat, AppiumDriver driver) {
    JavascriptExecutor js = (JavascriptExecutor) driver;
    HashMap<String, Double> swipeObj = new HashMap<String, Double>();
    swipeObj.put("startX", startX);
    swipeObj.put("startY", startY);
    swipeObj.put("endX", endX);
    swipeObj.put("endY", endY);
    swipeObj.put("duration", duration);
    for (int i = 0; i < repeat; i++) {
        try {
            js.executeScript("mobile:swipe", swipeObj);
            System.out.println("滑动屏幕成功");
        } catch (WebDriverException ex) {
            System.out.println("滑动屏幕失败");
        }
    }
}
