雅可可·马文多模块项目覆盖面

似乎有几个问题，这些问题已经很老了，从Java 8支持Jacoco开始就发生了变化。

我的项目包含以下结构

pom.xml
|
|
-----sub module A pom.xml
|
|
-----sub module B pom.xml
|
|
-----sub module C pom.xml

我已经配置了这样的main pom

主要聚甲醛.xml

我正在执行此命令。我可以看到jacoco.exec正在生成，但是我无法看到任何HTML报告正在验证数据。mvn clean package

请帮帮我。另一点是，我的配置对于项目是否正确？Multi-Module

更新

已识别问题。 更改为<destFile>${project.basedir}/../target/jacoco.exec</destFile><destFile>${project.basedir}/target/jacoco.exec</destFile>

现在，它正在为各个模块生成报告。任何想法如何生成合并报告
