Metadata

Per-directory repository metadata repository-metadata.xml.

A directory may represent 3 types of content: "groupId", "groupId/artifactId" or "groupId/artifactId/version".

Most metadata content has a meaning when the directory represents a "groupId/artifactId" (groupId, artifactId, versioning)

Attribute Type Description
modelVersion String The version of the underlying metadata model.
Element Type Description
groupId String The groupId when this directory represents "groupId/artifactId" or "groupId/artifactId/version".
artifactId String The artifactId when this directory represents "groupId/artifactId" or "groupId/artifactId/version".
versioning Versioning Versioning information when this directory represents "groupId/artifactId" or "groupId/artifactId/version".
version String The base version (i.e. ending in -SNAPSHOT) when this directory represents a "groupId/artifactId/version" for a SNAPSHOT.
plugins/plugin* List<Plugin> (Many) The set of plugins when this directory represents a "groupId".

versioning

Versioning information for "groupId/artifactId" or "groupId/artifactId/version" SNAPSHOT

Element Type Description
latest String What the last version added to the directory is, including both releases and snapshots ("groupId/artifactId" directory only)
release String What the last version added to the directory is, for the releases only ("groupId/artifactId" directory only)
versions/version* List<String> (Many) Versions available of the artifact (both releases and snapshots) ("groupId/artifactId" directory only)
lastUpdated String When the metadata was last updated (both "groupId/artifactId" and "groupId/artifactId/version" directories). The timestamp is expressed using UTC in the format yyyyMMddHHmmss.
snapshot Snapshot The current snapshot data in use for this version ("groupId/artifactId/version" only)
snapshotVersions/snapshotVersion* List<SnapshotVersion> (Many) Information for each sub-artifact available in this artifact snapshot. This is only the most recent SNAPSHOT for each unique extension/classifier combination.

snapshot

Snapshot data for the last artifact corresponding to the SNAPSHOT base version

Element Type Description
timestamp String The timestamp when this version was deployed. The timestamp is expressed using UTC in the format yyyyMMdd.HHmmss.
buildNumber int The incremental build number

Default value: 0
localCopy boolean Whether to use a local copy instead (with filename that includes the base version)

Default value: false

snapshotVersion

Versioning information for a sub-artifact of the current snapshot artifact.

Element Type Description
classifier String The classifier of the sub-artifact. Each classifier and extension pair may only appear once.

Default value:

extension String The file extension of the sub-artifact. Each classifier and extension pair may only appear once.
value String The resolved snapshot version of the sub-artifact.
updated String The timestamp when this version information was last updated. The timestamp is expressed using UTC in the format yyyyMMddHHmmss.

plugin

Mapping information for a single plugin within this group.

Element Type Description
name String Display name for the plugin.
prefix String The plugin invocation prefix (i.e. eclipse for eclipse:eclipse)
artifactId String The plugin artifactId
