如何让 JaCoCo 与 Maven 和 JUnit 4.11 一起工作？

Question

我无法让 JaCoCo 与 Maven 一起工作。我一直运行宁

Skipping JaCoCo execution due to missing execution data file.

或

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

我似乎也无法通过 mvn clean test 让 JaCoCo 达到运行而我必须运行 mvn clean test jacoco:report 或 mvn clean test jacoco:check

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

Answer 1

这是因为您使用了 <pluginManagement> 标签，并且 <plugins> 被放入其中。

根据 Maven documentation on <pluginManagement>、

pluginManagement: is an element that is seen along side plugins. Plugin Management contains plugin elements in much the same way, except that rather than configuring plugin information for this particular project build, it is intended to configure project builds that inherit from this one. However, this only configures plugins that are actually referenced within the plugins element in the children or in the current POM. The children have every right to override pluginManagement definitions.

简而言之，如果是 multi-module Maven 项目，您将使用 <pluginManagement>。 this answer.

中有更多解释

我从 pom.xml 中删除了 <pluginManagement> 标签，现在构建工作正常并且正在生成 Jacoco 报告。
