I am using maven-compiler-plugin v2.5.1
我正在使用 maven-compiler-plugin v2.5.1
when I am doing clean test from eclipse it creates the target/jacoco.exec file, once it it created I run it with jacoco:report and it creates the report as well. But the report shows all the packages with 0% code coverage except one package.
当我从 Eclipse 进行干净测试时，它会创建 target/jacoco.exec 文件，一旦它创建，我就用 jacoco:report 运行它，它也会创建报告。但是该报告显示了除一个包之外所有代码覆盖率为 0% 的包。
When I run the report for the same set of classes using cobertura it is showing us the code coverage correctly.
当我使用 cobertura 为同一组类运行报告时，它正确地向我们显示了代码覆盖率。
Can someone please help us in understanding what is the issue.
有人可以帮助我们了解问题所在。

I am using powermock in my application which does not play well with the online instrumentation performed by JaCoCo. so using the offline instrumentation and excluding some clousure classes it worked for me.
我在我的应用程序中使用了 powermock，它不能很好地与 JaCoCo 执行的在线检测配合使用。所以使用离线检测并排除一些对我有用的 clouse 类。
I am running the job using mvn clean verify install, below is the changed snippet of my pom.

Change your jacoco plugin config to
将您的 jacoco 插件配置更改为
<plugin>
<groupId>org.jacoco</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
<version>0.7.5.201505241946</version>
<configuration>
<dataFile>target/jacoco.exec</dataFile>
</configuration>
<executions>
<execution>
<id>pre-unit-test</id>
<goals>
<goal>prepare-agent</goal>
</goals>
<configuration>
<propertyName>jacoco.agent.argLine</propertyName>
<destFile>target/jacoco.exec</destFile>
</configuration>
</execution>
<execution>
<id>default-report</id>
<phase>verify</phase>
<goals>
<goal>report</goal>
</goals>
</execution>
</executions>
</plugin>
and then invoke mvn verify
然后调用 mvn verify
Check also the output of maven, it will hint you whether jacoco was executed within your tests.
还要检查 maven 的输出，它会提示您是否在测试中执行了 jacoco。
