                        The type of dependency. This defaults to
                        <code>jar</code>
                        . 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
                        <code>jar</code>
                        ,
                        <code>war</code>
                        ,
                        <code>ejb-client</code>
                        and
                        <code>test-jar</code>
                        . New types can be defined by plugins that set
                        <code>extensions</code>
                        to
                        <code>true</code>
                        , so this is not a complete list.

                        . 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.
                        <code>relativePath</code>
                        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.
