我设置了一个Jenkins作业来运行一个使用JMeter GUI构建的Jmeter测试，但是构建总是失败，并报告了一个NonGUIDriver java.lang.NullPointerException。
这是JMeter.log文件中显示的内容：

经过太多的搜索，我在github中找到了this thread。
从本质上讲，为了使项目成功构建，我所要做的就是在.jmx测试文件中搜索并将
HTTPSamplerProxy替换为HTTPSampler，现在jenkins项目的构建非常顺利。tpgth1q72#
我遇到了同样的问题。问题是远程服务器上的Jmeter版本是2.6，而创建.jmx文件的版本是2.8。因此，我安装了一个较低的版本，并重新创建了移动到远程服务器上的.jmx文件，一切正常😀

我解决了这个问题，请参考下面的截图。

在我的例子中，从JMX中删除
<ResultCollector>解决了这个问题。JMX在jmeter 3.1中创建，在jmeter 2.11下运行JMX。kadbb4595#
我在jmeter-maven-plugin 2.9.0下运行jmeter 4.0时也遇到了同样的问题。在运行测试之前运行mvn clean可以解决这个问题。
