我能够通过命令提示符运行 selenium webdriver 支持的脚本触发 ant。
测试脚本运行成功，生成的 Junit 测试结果在报告中带有屏幕截图。
在 Jenkins 上运行相同的脚本，chrome 浏览器未启动，构建成功，但是 Junit 测试报告不完整，屏幕截图没有出现。看起来脚本中的操作也没有执行。
请参阅下面来自 Jenkins 控制台输出的日志以了解该作业。
我的测试 PC 的操作系统是 windows XP 和 chrome ver30。通过 Jenkins 运行时，相同的脚本在 IE 和 Firefox 浏览器上运行良好（能够看到浏览器启动并执行 action.pls 协助。
