无法解析类异常：org.apache.jmeter.protocol.http.sampler.HTTPSamplerProxy

Question

当我尝试通过 java 代码从 eclipse 运行 JMX 文件时，我收到如下错误代码和错误。

我尝试通过添加插件管理器。

Answer 1

您的pom.xml文件似乎缺少ApacheJMeter_http 依赖项

最小的依赖集是：

<dependencies>
    <dependency>
        <groupId>org.apache.jmeter</groupId>
        <artifactId>ApacheJMeter_java</artifactId>
        <version>5.1.1</version>
    </dependency>
    <dependency>
        <groupId>org.apache.jmeter</groupId>
        <artifactId>ApacheJMeter_http</artifactId>
        <version>5.1.1</version>
    </dependency>
</dependencies>

如果您的测试依赖于其他测试元素，您需要找到所需的库并将其显式声明为项目依赖项。
