jacoco:report-aggregate 要么得到浅层覆盖，要么根本 none

Question

我有一个大型的多模块 Maven 构建，目前混合了 PowerMock 和 Mockito 测试（很快将所有 PowerMock 测试移至 Mockito）。父 pom 中的默认 jacoco-maven-plugin 配置用于 "offline" 检测，但带有 Mockito 测试的一个模块正在使用在线检测。我相信模块中的每个 jacoco.exec 文件都已正确构建。

其中一个名为 "jacoco-aggregate" 的子模块尝试使用 "merge" 和 "report-aggregate" 目标。我正在使用 "merge" 因为我正在与 SonarQube 集成，而我们使用的版本只允许一个 exec 文件。从输出中我可以看到，"merge" 目标似乎工作正常。

"report-aggregate" 目标似乎有问题。它目前根本没有产生任何报道。显示的table为空

以下是我在 jacoco 子模块本身中构建时得到的当前输出：

请注意，我正在为其他 jacoco 目标指定执行，因为那些是在父 pom 中指定的，预计将由普通代码模块使用。将 "phase" 设置为 "none" 是一种有效禁用该目标的方法（并不是说它特别干净）。

在我运行在 "jacoco-aggregate" 中手动构建之前，我查看了其他模块中引用的几个 "jacoco.exec" 文件，它们都存在并且不存在空。

Answer 1

首先 - 似乎您在 report-aggregate 之后执行 merge，所以最后一个没有看到 jacoco.exec。

另请注意，report-aggregate 会调查反应堆项目，即如果您有

root
  \child_1
  \child_2

然后在 root 中执行 mvn ... 期间，反应堆将包含所有 3 个，而在 cd child_2 && mvn ... 执行期间，反应堆将仅包含 child_2.

jacoco:report-aggregate 要么得到浅层覆盖，要么根本 none

jacoco:report-aggregate either gets shallow coverage or none at all
