jar
type
4.0.0
jar. While it usually represents the extension on
the filename of the dependency, that is not always the case. A type can be mapped to a different
extension and a classifier.
The type often correspongs to the packaging used, though this is also not always the case.
Some examples are jar, war, ejb-client and test-jar.
New types can be defined by plugins that set
extensions to true, so this is not a complete list.

The default value is ../pom.xml.
Maven looks for the parent pom first in the reactor of currently building projects, then in this location on
the filesystem, then the local repository, and lastly in the remote repo.
relativePath allows you to select a different location,
for example when your structure is flat, or deeper without an intermediate parent pom.
However, the group ID, artifact ID and version are still required,
and must match the file in the location given or it will revert to the repository for the POM.
This feature is only for enhancing the development in a local checkout of that project.
