无法初始化 class org.apache.jmeter.protocol.Z80791B3AE7002CB88C24687F8ZFA9。

Question

嗨，我正在尝试在 IntelliJ 中运行我的 java 代码，并且还尝试初始化 apache JMeter，但有人可以解释一下可能是错的吗？

Answer 1

根据NoClassDefFoundError描述：

如果 Java 虚拟机或 ClassLoader 实例尝试加载 class 的定义（作为正常方法调用的一部分或作为使用新表达式创建新实例的一部分）并且找不到 ZA2F2ED2AA2A4F8EBC2CBB4C21 的定义。

搜索到的 class 定义在编译当前正在执行的 class 时存在，但无法再找到该定义。

你至少需要：

1. JMeter 的“lib”文件夹中的所有内容
2. JMeter 的“lib/ext”文件夹中的所有内容

在您的项目类路径中，一旦完成，您将能够运行您的代码。
