在 Maven 中运行时，JMeter 失败并出现 ClassNotFoundException

Question

我创建了一个 JMeter 测试文件，它运行我用 java 编写的一些测试

当我在 JMeter 中运行文件时，它们运行良好并且测试通过。现在我已经将 maven 配置为运行 JMX 文件，并且当我运行验证目标时，它会执行 JMX 文件。但是现在它失败并显示以下错误消息：

JMeter.jmx.log: "jmeter.protocol.java.sampler.JUnitSampler: ClassNotFoundException:: com.mynamespace.tests.product.ProductTest"

Jmeter.jtl：“无法创建 com.mynamespace.tests.product.ProductTest 的实例，原因可能是缺少空构造函数和一个字符串构造函数，或者无法实例化构造函数，请检查 jmeter 日志文件中的警告消息”

为了让 JMeter 知道该类，我构建了一个 jar 并将其复制到 Jmeter 的 lib 目录中。运行 jmeter maven 插件时我需要做类似的事情吗？ - 在运行验证目标时，它应该能够看到项目构建时的类..

添加到 pom.xml：

            <plugin>
          <groupId>com.lazerycode.jmeter</groupId>
          <artifactId>jmeter-maven-plugin</artifactId>

您需要修改 pom.xml 文件以将您的 jar 工件作为依赖项包含在内。比如：

  <plugin>
      <groupId>com.lazerycode.jmeter</groupId>
      <artifactId>jmeter-maven-plugin</artifactId>
      <version>1.10.0</version>
      <executions>
          <execution>
              <phase>verify</phase>
              <id>jmeter-tests</id>

              <goals>
                  <goal>jmeter</goal>
              </goals>
          </execution>
      </executions>
      <dependencies>
          <dependency>
              <groupId>com.mynamespace.tests.product</groupId>
              <artifactId>com.mynamespace.tests.product.ProductTest</artifactId>
              <version>1.0-SNAPSHOT</version>
          </dependency>
      </dependencies>
  </plugin>
