 Depending on what the directory represents ("groupId", "groupId/artifactId" or "groupId/artifactId/version"),
 the Maven Repository Metadata file contains 3 different sets of metadata:

 [[1]] in a "groupId" directory: a "groupId" directory may contain Maven plugins artifacts, which are described in metadata's <<<plugins>>> element,

 [[2]] in a "groupId/artifactId" directory: metadata describes <<<groupId>>>, <<<artifactId>>> and <<<versioning>>> element that

    <artifactId>p0</artifactId>

    <version>1.0</version>
