java - 如何在maven中添加JaCoCo

Question

我已经使用 JUnit 编写了一个单元测试用例，现在我想在我正在移动 3.2.1 的构建工具中添加 JaCoCo。我是 Maven 的新手。添加时，我不得不怀疑我要将它添加到依赖项还是插件中？两者都有，如下图

<plugin>
  <groupId>org.jacoco</groupId>
  <artifactId>jacoco-maven-plugin</artifactId>
  <version>0.7.2-SNAPSHOT</version>
</plugin>

<dependency>
   <groupId>org.codehaus.sonar.plugins</groupId>
   <artifactId>sonar-jacoco-plugin</artifactId>
   <version>3.2.1</version>
</dependency>

我希望将它附加到依赖项中，对于插件来说是否足够？

请任何机构澄清
