我正在尝试使用命令行在我的服务器上运行JMeter测试。我从我的Windows机器上连接ssh到rabbitMQ服务器，我在rabbitmq服务器上运行jmeter，我有想运行的jmx文件，但是当我运行像“jmeter -n -t server.jmx”这样的命令时“我得到这样的错误”NonGUIDriver中的错误java.lang.NullPointerException“
我经历了很多问题和答案，但没有一个能解决我的问题。我已将jar文件包含在lib / ext文件夹中。我已经检查了我的jmeter版本，比较我的Windows机器和Linux服务器，在.jmx测试文件等中搜索并替换HTTPSamplerProxy和HTTPSampler等。
这是我的“jmeter.log”文件：
