org.openqa.selenium.UnsupportedCommandException: touchScroll

Description

When I open h5 using chrome, I swipe the page by implementing the HasTouchScreen method, prompting failure and error

Environment

• java client build version or git revision if you use some shapshot: 6.1.0
• Appium server version or git revision if you use some shapshot: 1.8.1
• Desktop OS/version used to run Appium if necessary:
• Node.js version (unless using Appium.app|exe) or Appium CLI or Appium.app|exe:
• Mobile platform/version under test: android
• Real device or emulator/simulator:

Details

I want to use the TouchActions scroll method, but when I implemented the HasTouchScreen interface, the page did not swipe, but directly reported an error. When I was in java-clien 5.0.4 and selenium 3.5.2 version, I could swipe normally, but I could not swipe at java-client 6.1.0 selenium 3.12.0 ~ 3.14.0, and there was an error

Code To Reproduce Issue [ Good To Have ]

public class TestCase{
//
private RemoteWebDriver driver;
RemoteTouchScreen touch;

public TouchScreen getTouch() {
return touch;
}
@Test
public void beforeMethod() {
try {
DesiredCapabilities caps = new DesiredCapabilities();
caps.setCapability(MobileCapabilityType.PLATFORM_NAME, "android");
caps.setCapability(MobileCapabilityType.DEVICE_NAME, "xxxxxxx");
caps.setCapability(MobileCapabilityType.NEW_COMMAND_TIMEOUT, 600);
caps.setCapability(AndroidMobileCapabilityType.NO_SIGN, true);
caps.setCapability(AndroidMobileCapabilityType.UNICODE_KEYBOARD, true);
caps.setCapability(AndroidMobileCapabilityType.RESET_KEYBOARD, true);
caps.setCapability(AndroidMobileCapabilityType.BROWSER_NAME,"Chrome");
caps.setCapability(MobileCapabilityType.NO_RESET, true);
caps.setCapability(AndroidMobileCapabilityType.RECREATE_CHROME_DRIVER_SESSIONS, true);
driver = new AndroidDriverChild(new URL("http://127.0.0.1:4723/wd/hub"), caps);
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
} catch (MalformedURLException e) {
e.printStackTrace();
}
try {
Thread.sleep(5000);
} catch (InterruptedException e) {
e.printStackTrace();
}
driver.get("http://www.sogou.com");
try {
Thread.sleep(5000);
} catch (InterruptedException e) {
e.printStackTrace();
}
TouchActions touchActions = new TouchActions(driver);
touchActions.scroll(600, 1200).perform();

    public class AndroidDriverChild extends AndroidDriver implements HasTouchScreen {
    private RemoteTouchScreen touch;

    public AndroidDriverChild(URL remoteAddress, Capabilities desiredCapabilities) {
        super(remoteAddress, desiredCapabilities);
        touch = new RemoteTouchScreen(getExecuteMethod());
    }

    public TouchScreen getTouch() {
        return touch;
    }
}

}

Link to Appium logs

Can be provided if needed

Start by tracing RemoteTouchScreen.scroll and TouchActions.scroll through AppiumExecutionMethod and the AppiumCommandExecutor, using the reported java-client 6.1.0, Selenium 3.12.0–3.14.0, and Appium 1.8.1 versions. Reproduce the touchScroll failure with the supplied Android Chrome example and compare it with the older working versions; done means the supported scroll path works or the compatibility limitation is clearly established and covered by a regression test.
