Maven jacoco：报表聚合要么覆盖范围很浅，要么根本没有

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测试转移到Mockito）。父pom中默认的JacocoMaven插件配置用于“离线”插装，但是带有Mockito测试的模块使用在线插装。我相信模块中的每个jacoco.exec文件都是正确构建的

其中一个子模块称为“jacocoaggregate”，它只是尝试使用“合并”和“报告聚合”目标。我之所以使用“合并”，是因为我正在与SonarQube集成，而我们使用的版本只允许一个exec文件。从我看到的输出来看，“合并”目标似乎工作正常

“报告汇总”目标似乎有问题。目前根本没有覆盖范围。显示的表格为空

以下是我在构建jacoco子模块时得到的电流输出：
