Xvfb和修昔底德/Selenium运行Firefox的默认路径

Question

CI Jenkins在非root用户的情况下运行在CentOS无头计算机上。

Xvfb packege已安装，当我尝试"How can I specify a display？"中的提示时？，即在控制台中手动设置

export DISPLAY=127.0.0.1:0
Xvfb :0
firefox &

它工作起来了——Xvfb输出显示一些firefox请求，firefox输出到控制台。

当我从maven运行同样的东西时，什么都不会发生。请查看我的pom.xml：

firefox和Xvfb实用程序是为jenkins-linux用户和chmoded777选择的，因此权限不是问题的根源。

export DISPLAY=127.0.0.1:0

设置为预生成操作。Xvfb应该由maven selenium插件启动，它是根据mavn输出和自己的Xvfb日志启动的。

我想知道修昔底德/Selenium是如何定义如何找到要运行的Firefox二进制文件的？也许它们应该以某种方式在jenkins配置文件中显式配置？

Answer 1

事实上，我无法以我喜欢的方式解决这个问题，因为尽管有DISPLAY变量的任何组合，将文件和二进制文件归因于jenkins用户并返回到root，但不可能从maven插件配置中运行Xvfb。然而，Xvfb-Jenkins插件运行良好！如果对我来说更完美，因为我不再需要不同的mvn配置文件来在本地机器和CI上运行（插件的Xvfb运行存储为jenkins配置文件），
