如何让JaCoCo与Maven和JUnit 4.11合作？

Question

我很难让JaCoCo和Maven合作。我一直遇到任何一个。

Skipping JaCoCo execution due to missing execution data file.

或者

The parameters 'rules' for goal org.jacoco:jacoco-maven-plugin:0.8.2:check are missing or invalid

我似乎也无法让JaCoCo只运行mvn clean test，相反，我必须运行 mvn-clean test-JaCoCo:reportor

我尝试了多种编辑POM文件的方法，例如添加destFile和dataFile的配置，以及此处的POM设置：https://howtodoinjava.com/junit5/jacoco-test-coverage/还有这里https://www.lambdatest.com/blog/reporting-code-coverage-using-maven-and-jacoco-plugin/。任何帮助都将不胜感激。下面是我的POM文件

Answer 1

这是因为您正在使用

根据上的Maven文档

pluginManagement:是一个可以在插件旁边看到的元素。插件管理以非常相似的方式包含插件元素，除了不是为这个特定的项目构建配置插件信息，而是打算配置从这个构建继承的项目构建。然而，这仅配置在子元素或当前POM中的plugins元素中实际引用的插件。孩子们完全有权利覆盖插件管理定义。

简而言之，您将使用

我删除了<代码>
