我正在努力让 Jenkins 运行 Selenium/Xvfb 来对项目进行一些功能测试。Jenkins 要么会挂起，作业永远无法完成，要么最终因错误而终止。这是使用 Xvfb 插件。这是最近的回溯之一——

这可能与 Xvfb 仍在运行的问题有关，即使我终止了该作业也是如此。以下是我的设置：
在构建之前启动 Xvfb，并在构建后将其关闭 = 已选中 Xvfb 特定显示名称 = 99 超时（秒） = 10 Xvfb 显示名称偏移量 = 0 记录 Xvfb 输出 = 已选中
我尝试使用注入环境变量插件添加以下环境变量——DISPLAY=:99.0
我尝试搜索日志，但在 Google 上找不到任何有关日志位置的信息。有人能帮我指出正确的方向吗？
