-Each file has a unique Maven specifier, consisting of a group ID, an artifact ID, a version, a file type and an optional qualifier.
-By default, the group ID is equal to the addon namespace, the artifact ID to the addon ID, the version to the addon version and
-the qualifier to file ID. Those values can be overwritten in this object. If the qualifier is set to an empty string, it will be
-removed from the Maven specifier. The file type is always equal to the file type of the `link`. If the group ID, addon ID and version
-all have their default values and the qualifier is an emptry string, the file type may not be `json`.
