我正在运行一个 shell 脚本来在 Jenkins 中执行测试用例。当我构建测试用例时，出现以下错误。
Failed to open connection to "session" message bus: Unable to autolaunch a dbus-daemon without a $DISPLAY for X11

我在 Jenkins 中使用自定义工作区，在我的情况下，它是“/demo/JarFolder”
并使用 shell 脚本（java -cp“./*:bin”org.testng.TestNG testng.xml）来构建它.
我是 Linux 新手，我正在使用 CentOS 7。我无法解决问题。
