最近，我在Jenkins的Firefox驱动程序中启动了web app jmeter案例时遇到了一个问题。
我可以在Jenkins服务器终端上使用非GUI模式成功运行它。 我也可以使用Jmeter UI在Jenkins服务器上成功运行它。 但是当我通过Jenkins工作踢它时，它通过以下错误：
jmeter -n -t jmeter.jmx -l result.jtl
Writing log file to: /var/lib/jenkins/workspace/test/srm-bermuda/jmeter.log
Error in NonGUIDriver java.lang.IllegalArgumentException: Problem loading XML from:'/var/lib/jenkins/workspace/test/srm-bermuda/jmeter.jmx', missing class com.thoughtworks.xstream.converters.ConversionException: org/openqa/selenium/remote/SessionNotFoundException : org/openqa/selenium/remote/SessionNotFoundException

如果有人可以帮助我，那就太好了！
更新了完整的jenkins日志，其中也打印出jmeter.log：
+ cd srm-bermuda
+ ls
jmeter.jmx
jmeter.log
jmeter_UI.jmx
simple.jmx
success_login.jmx

+ result=result.jtl
+ [ -f result.jtl ]

答案 0 :(得分：1)
此“NoClassDefFoundError”错误通常表示包含该类的引用.jar文件不在Java Classpath中，或者在JMeter Classpath中。对于JMeter插件，最常见的情况是：人们将插件库安装到“lib / ext”文件夹中，但忘记将依赖项安装到其JMeter安装的“lib”文件夹中。你最有可能患上同样的痛苦。所以我建议2个选项：
比较JMeter安装的“lib”和“lib / ext”文件夹：
并同步所有更改，以使文件夹完全相同。
安装JMeter插件并使其保持最新的推荐方法是使用JMeter Plugins Manager，这样您就可以“干净”地分发最新的JMeter并使用插件管理器安装所有必需的插件
