尝试使用jacoco的脱机工具获取覆盖范围（由于powermock测试用例，无法使用即时检测工具），将jacocoagent.jar添加到surefire插件的classpath中，如下所示。将“ org.jacoco.agent-0.7.7.201606060606-runtime.jar”（从本地maven存储库中）重命名为“ jacocoagent.jar”，并将其保存在此pom.xml所在的文件夹中。即使将其添加到classpath之后也是如此。

pom.xml片段（surefire-插件配置）

       <plugin>
             <groupId>org.apache.maven.plugins</groupId>
             <artifactId>maven-surefire-plugin</artifactId>
             <configuration>
                     <forkmode>once</forkmode>
                    <additionalClasspathElements>
            <additionalClasspathElement>jacocoagent.jar</additionalClasspathElement>
                                        </additionalClasspathElements>
              </configuration>
     </plugin>

在控制台上看到的异常：
