java - 无法初始化类 org.apache.jmeter.protocol.http.parser.CssParser - JMeter

问题描述

我正在尝试在 Apache JMeter 5.2 上运行 LoadTest，当我尝试运行测试时，它显示了这个错误 =>

解决方案

很可能您的 JMeter 安装以某种方式损坏，尝试使用JMeter 插件管理器jmeter - HTTP Protocol Support卸载组件，然后重新安装

在此处输入图像描述

它应该可以解决您的安装问题。

另请注意，根据 JMeter 最佳实践，您应该始终使用最新版本的 JMeter，因此鉴于您当前的 JMeter 安装已损坏，可能是升级到JMeter 5.3的好时机（或JMeter 下载页面上提供的最新稳定版本）)
