在我的QUKUS应用程序中，我有2个模块，module-api和module-impl。这两个模块的单元测试都在module-impl中。当我运行mvn验证时，报告仅包含module-impl中代码的覆盖率。module-api中的代码为0%，即使我对它进行了单元测试。

但是，如果我将api测试从module-impl移动到module-api，那么我将获得module-api代码的正确覆盖率。为什么当我在单个模块中拥有所有测试时它不起作用？

我遵循官方指南：https://quarkus.io/guides/tests-with-coverage#coverage-for-tests-not-using-quarkustest

项目结构：

|- pom.xml (root)
|
|-- module-api
|--- src
|---- main
|--- pom.xml
|
|-- module-impl
|--- src
|---- main
|---- test
|--- pom.xml
