Maven Repository Metadata Model

Metadata

Per-directory repository metadata, for directories representing un-versioned artifact, snapshot artifact or a group containing Maven plugins.

Notice that most metadata content has a meaning when the directory represents an artifact (groupId, artifactId, versioning), but plugins is used when the directory represents a group.
