java - Selenium Java - - RemoteWebDriver 错误/异常

Question

java版本:1.8

selenium 版本:最新截至 2017 年 4 月

集线器/网格已设置在另一台机器上，该机器是 ec2 windows 实例。节点注册成功。

集线器和节点控制台上没有错误。我可以在浏览器上看到控制台，其中包含已注册的节点和公开的浏览器。

java -Dwebdriver.gecko.driver=C:\selenium_grid\geckodriver\geckodriver.exe -jar selenium-server-standalone-3.4.0.jar -role hub -host <ipaddress> -port 4444

java -jar selenium-server-standalone-3.4.0.jar -role node -port 5555 -hub http://127.0.0.1:4444/grid/register -browser "browserName=firefox,platform=WINDOWS" -browser "browserName=opera,platform=WINDOWS" -browser "browserName=safari,platform=WINDOWS" -browser "browserName=internet explorer,platform=WINDOWS" -browser "browserName=chrome,platform=WINDOWS"

webdriver = new RemoteWebDriver(seleniumGridURL, desiredCapabilities);

public enum DriverType implements DriverSetup {

FIREFOX {
    public DesiredCapabilities getDesiredCapabilities(Proxy proxySettings) {
        DesiredCapabilities capabilities = DesiredCapabilities.firefox();
        capabilities.setCapability("marionette", true);
        return addProxySettings(capabilities, proxySettings);
    }

    public WebDriver getWebDriverObject(DesiredCapabilities capabilities) {
        return new FirefoxDriver(capabilities);
    }
}}`

org.openqa.selenium.WebDriverException:

尝试按照建议启用调试:
java -jar selenium-server-standalone-3.4.0.jar -debug -log c:\selenium_grid\grid.log -role node -port 5555 -hub http://127.0.0.1:4444/grid/register -browser "browserName=firefox,platform=WINDOWS" -browser "browserName=opera,platform=WINDOWS" -browser "browserName=safari,platform=WINDOWS" -browser "browserName=internet explorer,platform=WINDOWS" -browser "browserName=chrome,platform=WINDOWS"

Exception in thread "main" com.beust.jcommander.ParameterException: "-debug": couldn't convert "-log" to a boolean

这是 aws VPC 和私有(private) IP 以及在 Windows 防火墙中打开 TCP 和 UDP 端口 + 修改 EC2 实例中的 sec 组(Windows 计算机的传入端口)的网络问题。
