我正在学习一个教程，介绍如何使用maven和eclipse在本地和jenkins 服务器上创建和运行 javaselenium 脚本。
我的脚本非常基本，当通过 maven 和 TestNG 通过 eclipse 运行时在本地运行良好。 当我在 Jenkins 上运行它们时，构建需要 3 分钟到 15 分钟，然后通常会因超时渲染问题而失败。
我的脚本在本地运行时最多只需要大约 2 分钟。
以前有人遇到过这个问题吗？ 我不确定为什么它们超时。

。暗示ChromeDriver无法启动/生成新的WebBrowser，即Chrome浏览器会话。
您的主要问题是您使用的二进制文件版本之间的不兼容，如下所示：
- 您正在使用的 chromedriver=78.0.3904.105
- 您正在使用的 chrome=78.0.3904.108
- 您的Selenium客户端版本是2.45.0的2015-02-27 09：10：26，这是古老的，几乎5年的历史。
- 您的JDK版本是1.8.0_101，这是非常古老的。
所以JDK v8u101、Selenium Client v2.45.0、ChromeDriver v78.0和Chrome浏览器v78.0之间存在明显的不匹配
。溶液
确保：
- JDK已升级到当前级别 JDK 8u222。
- 硒已升级到当前级别 版本 3.141.59。
- 通过IDE清理项目工作中心，并仅使用所需的依赖项重新生成项目。
- 如果您的基本 Web 客户端版本太旧，请通过Revo 卸载程序将其卸载，并安装最新的 GA 和已发布版本的Web 客户端。
- 重新启动系统。
- 以非 root用户身份执行
