我只是尝试使用插件Extras，Hadoop，ExtraLibs和Webdriver在Jmeter上启动webdrivertest。 （全部1.3.0） 当我尝试启动脚本时出现以下错误：
Chrome + IE：

Apache JMeter版本2.13
Java 1.8.0.45
我也使用Jmeter 2.13和相同的插件（1.2.1），它完美地工作。但是为了测试我需要1.3插件。
有没有人使用Jmeter和插件1.3并得到同样的错误？

你有一个问题你在lib中有不同版本的同一个JAR：
您需要保留每个版本的最新版本，而不是两者。
请参阅以下完整的教程：

jmeter.JMeter：
未捕获的异常：java.lang.NoClassDefFoundError： 组织/ openqa /硒/ OS / Kernel32中
要修复上述错误，请在此处下载JNA jar及其依赖项：

并将其放在lib文件夹中。
