Selenium Webdriver Chromedriver在无头模式下启动超时

我正在使用Selenium Webdriver,Ruby 32位1.9.3,Chromedriver v2.9.248315,Chrome 38.0.2125.111 m以及Jenkins 1.588的本地实例

宝石:黄瓜(1.3.17),selenium-webdriver(2.43.0),watir-webdriver(0.6.11)(如果你认为有必要可以提供所有其他的清单)

Windows 7 Professional 64位版.

运行Jenkins作业时,如果使用chromedriver启动Chrome,然后尝试与其进行交互,则会出现超时错误.通过命令提示符窗口在我的桌面上执行相同操作时,它可以正常工作.运行相同的Jenkins工作,启动Firefox而不是Chrome,它完美运行.

简单的例子(C:\ test.rb):

require 'watir-webdriver'
require 'selenium-webdriver'
client = Selenium::WebDriver::Remote::Http::Default.new
$browser = Watir::Browser.new :chrome, :http_client => client
$browser.driver.manage.window.maximize
$browser.close

Jenkins作业配置为运行Windows批处理命令:

cd \
ruby test.rb

我运行作业时的输出:

我尝试在Jenkins服务中启用"允许服务与桌面交互",然后观察窗口(在更复杂的情况下)并打开Chrome窗口,但什么都不做.我最初遇到了"$ browser.cookies.clear"的问题,在评论出该行后,我现在遇到了与$ browser.driver.manage.window.maximize这行相同的问题.

我正在运行复杂的黄瓜场景,使用Chromedriver没有任何问题.然后我重建了我的PC,安装了Jenkins,Ruby,Chromedriver(将两者都添加到PATH)并将旧作业复制到我的新Jenkins安装中后,我遇到了上述问题.然后我创建了上面的简单示例,测试了它并创建了这篇文章.

如果有人对我如何让Chromedriver再次工作有任何想法,那就太棒了.
