自动化 ios 应用中遇到一个邮编的输入框，输入中会弹出一个数字键盘

可以正常输入，但输入完成后使用'driver.hidekeyboard();' 隐藏无效,
webdriver 报错org.openqa.selenium.WebDriverException: An unknown server-side error occurred while processing the command. Original error: [object Object]

网上有看到使用带参数的，官网库里也有实现，
https://github.com/appium/java-client/blob/1991a8a0f9e4a3ff467dbb713cb5c51c8edc060f/src/main/java/io/appium/java_client/HidesKeyboardWithKeyName.java
但 import 了还是无法使用带参数的重载方法
The method hideKeyboard() in the type HidesKeyboard is not applicable for the arguments (String, String)

求助！
