Question

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，报告一个NonGUIDriver java.lang.NullPointerException。

这是JMeter.log文件中显示的内容：

Answer 1

经过太多的狩猎，我在github中找到了this thread。

基本上，为了使项目成功构建，我所要做的就是在.jmx测试文件中用HTTPSamplerProxy搜索并替换HTTPSampler，而jenkins项目现在不需要拴住。快乐！

Answer 3

就我而言，从JMX删除<ResultCollector>可解决此问题。在jmeter 3.1中创建的JMX，在jmeter 2.11下运行JMX。
