Question

尝试使用离线检测通过jacoco进行覆盖（不能使用即时检测：由于powermock测试用例）用于maven项目。在surefire插件中将jacocoagent.jar添加到classpath，如下所示。将“org.jacoco.agent-0.7.7.201606060606-runtime.jar”（从本地maven存储库）重命名为“jacocoagent.jar”并将其保存在此pom.xml所在的同一文件夹中。我在下面点击甚至在将其添加到类路径后也是例外。

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>

在控制台上看到异常：

Number of foreign imports: 1

遵循的步骤：

“mvn compile”。
“mvn org.jacoco：jacoco-maven-plugin：instrument”
“mvn test” - 此步骤引发异常。

请告诉我如何摆脱这种异常？那是添加类路径的正确位置吗？（在surefire插件中）或者应该在哪里指定??

谢谢。

获得Sonar + JaCoCo + PowerMock的

dr. macphail's trance article为我做了这个工作：

Values in the KV store cannot be larger than 512kb.

正如博文的评论部分所述：

如果您的默认argLine不是“简单”，您可能需要使用以下代码段：

{argLine} -XX：-UseSplitVerifier

否则您可能会遇到ClassNotFoundException - 例如java.lang.ClassNotFoundException：org.jacoco.agent.rt.RT

Jacoco - “引起：java.lang.ClassNotFoundException：org.jacoco.agent.rt.internal_6da5971.Offline”
