Method Detail

getRemoteChecksums

public static Optional<List<AetherUtilities.Checksum>> getRemoteChecksums(MavenArtifact artifact)
                                                                   throws MavenException

Throws:

MavenException

getRemoteArtifactMetadata

public static List<org.eclipse.aether.resolution.MetadataResult> getRemoteArtifactMetadata(MavenArtifact a)
                                                                                    throws MavenException

Returns the results of metadata requests regarding the request coordinates represented by the passed MavenArtifact.

Note that the passed artifact really only represents the expected location of the metadata to retrieve. Releases do not have metadata; snapshots have metadata and only the latest one will be returned. To get the meta data about the artifact regardless of its version, leave the version and packaging fields of the given MavenArtifact empty.

Parameters:

a -

Returns:

Throws:

MavenException
