我设置了一个 Jenkins 作业来运行使用 JMeter GUI 构建的 Jmeter 测试，但构建总是失败，报告 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 中找到了这个线程。

本质上，为了使项目构建成功，我所要做的就是在 .jmx 测试文件中搜索并替换为HTTPSamplerProxy，HTTPSamplerjenkins 项目现在可以顺利构建。喜悦！

我遇到过同样的问题。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。所以我安装了一个较低版本并重新创建了移动到远程服务器的 .jmx 文件，一切都很好

<ResultCollector>就我而言，从 JMX中删除解决了这个问题。在 jmeter 3.1 中创建的 JMX，在 jmeter 2.11 下运行 JMX。
