I have a single Java 11 library (jar) project whose Maven pom refers to a parent pom for common properties and configuration. There are no submodules and the parent pom doesn’t have any submodules. The parent pom contains a <pluginManagement> section. Both the parent pom and the project pom contain configuration for Jacoco, and as expected, the project pom overrides the parent. My parent pom doesn’t have a Jacoco entry in the <reporting> section.
