Field Summary

Fields

Modifier and Type	Field	Description
static final String	CONFIG_PROP_EXISTENCE_CHECK_RELABEL	Configuration to restore the legacy "existence check" behavior for artifacts that are present in the local repository but were cached from a remote repository unavailable in the current build context: when enabled, a bare remote existence check (no content transfer, hence no checksum validation) suffices to re-label the cached bytes as originating from the queried repository.
static final String	CONFIG_PROP_SIMPLE_LRM_INTEROP	Configuration to enable "interoperability" with Simple LRM, but this breaks RRF feature, hence this configuration is IGNORED when RRF is used, and is warmly recommended to leave it disabled even if no RRF is being used.
static final String	CONFIG_PROP_SNAPSHOT_NORMALIZATION	Configuration to enable "snapshot normalization", downloaded snapshots from remote with timestamped file names will have file names converted back to baseVersion.
static final String	CONFIG_PROPS_PREFIX
static final boolean	DEFAULT_EXISTENCE_CHECK_RELABEL
static final boolean	DEFAULT_SIMPLE_LRM_INTEROP

Field Details

CONFIG_PROPS_PREFIX

public static final String CONFIG_PROPS_PREFIX

See Also:

• Constant Field Values

CONFIG_PROP_SNAPSHOT_NORMALIZATION

public static final String CONFIG_PROP_SNAPSHOT_NORMALIZATION

Configuration to enable "snapshot normalization", downloaded snapshots from remote with timestamped file names will have file names converted back to baseVersion. It replaces the timestamped snapshot file name with a filename containing the SNAPSHOT qualifier only. This only affects resolving/retrieving artifacts but not uploading those.

• Constant Field Values

DEFAULT_SNAPSHOT_NORMALIZATION

public static final boolean DEFAULT_SNAPSHOT_NORMALIZATION

See Also:

• Constant Field Values

CONFIG_PROP_SIMPLE_LRM_INTEROP

public static final String CONFIG_PROP_SIMPLE_LRM_INTEROP

Configuration to enable "interoperability" with Simple LRM, but this breaks RRF feature, hence this configuration is IGNORED when RRF is used, and is warmly recommended to leave it disabled even if no RRF is being used.

See Also:

• Constant Field Values

DEFAULT_SIMPLE_LRM_INTEROP

CONFIG_PROP_EXISTENCE_CHECK_RELABEL

public static final String CONFIG_PROP_EXISTENCE_CHECK_RELABEL

Configuration to restore the legacy "existence check" behavior for artifacts that are present in the local repository but were cached from a remote repository unavailable in the current build context: when enabled, a bare remote existence check (no content transfer, hence no checksum validation) suffices to re-label the cached bytes as originating from the queried repository. When disabled (the default), the artifact is downloaded again through the regular transfer path, so the content is validated against the repository's checksum policy before it is registered with the local repository for that repository. Enabling this trades integrity for bandwidth and is warmly recommended to leave it disabled.

• Constant Field Values

DEFAULT_EXISTENCE_CHECK_RELABEL

public static final boolean DEFAULT_EXISTENCE_CHECK_RELABEL

Method Details

resolveArtifact

public org.eclipse.aether.resolution.ArtifactResult resolveArtifact(org.eclipse.aether.RepositorySystemSession session,
 org.eclipse.aether.resolution.ArtifactRequest request)
                                                             throws org.eclipse.aether.resolution.ArtifactResolutionException

Description copied from interface: ArtifactResolver

Resolves the path for an artifact. The artifact will be downloaded to the local repository if necessary. An artifact that is already resolved will be skipped and is not re-resolved. Note that this method assumes that any relocations have already been processed and the artifact coordinates are used as-is.

Specified by:

resolveArtifact in interface ArtifactResolver

Parameters:

session - The repository session, must not be null.

request - The resolution request, must not be null.

Returns:

The resolution result, never null.

Throws:

org.eclipse.aether.resolution.ArtifactResolutionException - If the artifact could not be resolved.

• Artifact.getFile()
• RepositorySystem.resolveArtifact(RepositorySystemSession, ArtifactRequest)

resolveArtifacts

public List<org.eclipse.aether.resolution.ArtifactResult> resolveArtifacts(org.eclipse.aether.RepositorySystemSession session,
 Collection<? extends org.eclipse.aether.resolution.ArtifactRequest> requests)
                                                                    throws org.eclipse.aether.resolution.ArtifactResolutionException

Description copied from interface: ArtifactResolver

Resolves the paths for a collection of artifacts. Artifacts will be downloaded to the local repository if necessary. Artifacts that are already resolved will be skipped and are not re-resolved. Note that this method assumes that any relocations have already been processed and the artifact coordinates are used as-is.

Specified by:

resolveArtifacts in interface ArtifactResolver

Parameters:

session - The repository session, must not be null.

requests - The resolution requests, must not be null.

Returns:

The resolution results (in request order), never null.

Throws:

org.eclipse.aether.resolution.ArtifactResolutionException - If any artifact could not be resolved.
