无法更改Winium驱动程序中的默认端口

Question

**即使指定了除9999以外的端口，winium驱动程序仍从9999启动。如何更改此默认端口？我正在使用以下代码在Windows 10上启动Winium驱动程序：

Code:**

public class outlook_poc {

    public static void main(String[] args) throws IOException {
    DesktopOptions option = new DesktopOptions();
    option.setApplicationPath("C:/Program Files/Microsoft Office/Office15/outlook.exe");
    System.setProperty("webdriver.winium.desktop.driver","C:\\Winium\\Winium.Desktop.Driver.exe");
    File driverpath = new File("C:/Downloads for Selenium/Winium.Desktop.Driver/Winium.Desktop.Driver.exe");    
    WiniumDriverService service = new WiniumDriverService.Builder().usingDriverExecutable(driverpath).usingPort(18434).withVerbose(true).withSilent(false).buildDesktopService();

    service.start();    
    System.out.println("test");

    WiniumDriver winDriver = new WiniumDriver(service,option);
    winDriver.findElementByName("OK").click();
    service.stop();
    }

}

Output trace :
