我有一些用Selenide/Java编写的测试。我的Windows上也有本地Jenkins，测试在这个Jenkins下运行得很好，但是我在外部Jenkins（Linux）上运行同一个仓库的测试时有问题。
Jenkins的日志：

在每次测试中，我们都有：java.lang.IllegalStateException:没有Web驱动程序绑定到当前线程：您有类似情况的经验吗？为什么在本地机器上测试是正确的，但在公司的主Jenkins上只有故障是由没有webdriver绑定到当前线程引起的？只有操作系统不同。这是Linux下的Jenkins配置问题吗？当我在本地运行测试时，使用Jenkins（使用Maven），我得到了同样的消息，但是WebDriver实际上已经创建并运行了我的测试用例。mvn清洁测试-Puat
测试中的铬声明：

@BeforeClass
public void setUp() throws Exception {
    Configuration.holdBrowserOpen = false;
    Configuration.browser = "chrome";
    Configuration.timeout = 10000;
    Configuration.headless = true;
    SelenideLogger.addListener("AllureSelenide", new AllureSelenide().screenshots(true).savePageSource(true));
    objReader.environmentPropertiesLoader();
}

现在我在Jenkins作业构建环境中检查了构建前启动Xvfb，并在构建后关闭它，我读到这一点非常重要，可能是Xvfb的原因，我不知道，现在在控制台中我有

java.io.IOException: Cannot run program "Xvfb": error=2, No such file or directory
