After migrating to Mavent 3.0.3 Parent poms in several Projects cannot be resolved anymore.
The Projects are structured in a default manner, so I set parent.relativePath
Make sure you Double-Check that the version you refer to in the child-pom is the same as that in the parent-pom. For me, I'd bumped version in the parent and had it as 3.1.0.0-RELEASE, but in the child-pom, I was still referring to the previous version via relativePath, and had it defined as 2.0.0.0-SNAPSHOT. It did not make any difference if I included just the parent directory, or had the "pom.xml" appended to the directory:
eric-project-parent
com.eric.common
2.0.0.0-SNAPSHOT
../../EricParentAsset/projects/eric-project-parent
