Description
Several (but not all) module pom.xml files refer to the parent specifying only the directory name. The correct syntax (as per Example 2 on https://maven.apache.org/guides/introduction/introduction-to-the-pom.html) is to include the relative path to parent pom.xml
<parent> <groupId>com.mycompany.app</groupId> <artifactId>my-app</artifactId> <version>1</version> <relativePath>../parent/pom.xml</relativePath> </parent>
