通过 Jenkins 运行 JMeter 脚本时出现以下错误。无法找出导致错误的原因。

【问题讨论】：

对 jenkins/jmeter 不太熟悉，但我建议从 jtl 文件中删除第一行（标题）。
谢谢@lucasvw。您对标题行创建问题是正确的。我将 text.jtl 的输出格式从 csv 更改为 xml，现在问题消失了。

标签： java jenkins jmeter

【解决方案1】：

根据Continuous Integration 101: How to Run JMeter With Jenkins 文章，这可能是由于格式不匹配，即Jenkins Performance Plugin 需要 XML 并获取 CSV。

对于您的前几次运行，我建议使用以下方法之一“告诉”JMeter 以 XML 格式存储其结果：

将 ``jmeter.save.saveservice.output_format=xml 行添加到 user.properties 文件（位于您的 /bin 文件夹中） JMeter 安装

通过-J命令行参数传递属性，如：C:\jmeter\bin\jmeter.bat -Jjmeter.save.saveservice.output_format=xml -n -t C:\jmeter\extras\Test.jmx -l Test.jtl

您还可以将 CSV 文件与性能插件一起使用。但是，这需要额外的配置，而 XML 文件可以开箱即用。
