jacoco合并目标找不到子模块的数据文件

Question

我有一个使用基于PowerMock的单元测试的大型Maven multiproject构建。我正在子模块中生成一个“target/jacoco.exec”，并在子模块的整个父pom中进行插件配置。我有一个附加的子模块，它只使用“报告-聚合”，并将各种子模块指定为依赖项。这些基本上都起作用了。

我现在正在尝试将这些数据与Sonarqube集成。安装的SonarQube Java Analyzer版本似乎不知道如何处理多个Jacoco.exec文件，它只处理单个文件。所以，我正在努力实现“合并”的目标。我阅读了关于这个目标的文档，但我显然没有做正确的事情，因为它只是没有找到数据文件。

如您所见，它执行了“合并”目标，但没有找到任何数据文件，尽管后来的“报告-聚合”目标找到了。

因此，我假设我指定文件集或与之相关的东西的方式在某种程度上是错误的。这里可能出了什么问题？

尝试将 （以及 （如果有））移动到 ，而不是 :

<plugin>
    <groupId>org.jacoco</groupId>
    <artifactId>jacoco-maven-plugin</artifactId>
    <version>0.7.8</version>
    <configuration>
        <fileSets>
            <fileSet>
                <directory>..</directory>
                <include>**/target/*.exec</include>
            </fileSet>
        </fileSets>
    </configuration>
    <executions>
