通过 JMeter 插件管理器获取 org.xml.sax.SAXParseException 但 JMeter 工具能够运行测试

Question

使用 JMeter v5.4.3 和 Jmeter plugins manager CMD (v1.7)：

我们在运行 JMX 上的 jmeter 插件管理器和所需的插件 未安装 时收到以下错误，但令人惊讶的是，相同的 JMX 是运行在 JMeter 上很好。我们在这里遗漏了什么吗？

Answer 1

为什么“令人惊讶”？您的 .jmx 脚本文件包含 XML.

中不允许的字符 null character

JMeter 会忽略这一点以提供最大的灵活性，而 JMeter 插件管理器不会。

插件管理器是一个 separate project，它与 JMeter 上游没有任何关系。

此外，这是一条 WARN 严重程度的消息，因此您可以忽略它（或者如果它导致自动日志分析出现问题，您可以 configure JMeter logging 通过添加下一行来不显示此警告log4j2.xml 文件)

<Logger name="org.jmeterplugins.repository.plugins.TestPlanAnalyzer" level="error" />
