Constructor Detail

ArtifactVersionCollector

public ArtifactVersionCollector()

Default constructor using default artifact comparator.

ArtifactVersionCollector

public ArtifactVersionCollector(Comparator<Artifact> sortingComparator)

Create a new collector using a custom sorting comparator.

Parameters:

sortingComparator - the comparator to determine the order of artifacts

Method Detail

collectArtifacts

public static Set<Artifact> collectArtifacts()

Collect all artifact coordinates and their versions using service loader.

Returns:

sorted set of artifacts

collect

public Set<Artifact> collect()

Collect all artifact coordinates and their versions using service loader.

Returns:

sorted set of artifacts

findArtifact

public static Artifact findArtifact(String groupId,
                                    String artifactId)

Find a given artifact by its coordinates (just without the version).

Parameters:

groupId - the group id

artifactId - the artifact id

Returns:

the artifact identified by its coordinates or null in case it is not found

findArtifactsByGroupId

public static Set<Artifact> findArtifactsByGroupId(String groupId,
                                                   boolean exact)

Find a set of artifacts by groupId or groupId prefix.

Parameters:

groupId - the groupId or groupId prefix

exact - true to check for exact groupId, false to use groupId as a prefix

Returns:

a set of artifacts matching the criteria

artifactsByGroupId

public Set<Artifact> artifactsByGroupId(String groupId,
                                        boolean exact)

Find a set of artifacts by groupId or groupId prefix. Use the instance sorting comparator to create Set.

Parameters:

groupId - the groupId or groupId prefix

exact - true to check for exact groupId, false to use groupId as a prefix

Returns:

a set of artifacts matching the criteria

iterateArtifacts

public static Artifact iterateArtifacts(ArtifactConsumer consumer)

Iterate list of artifacts and check them using a given lambda. See findArtifact(String, String) and artifactsByGroupId(String, boolean) for examples.

Parameters:

consumer - the artifact consumer (see ArtifactConsumer for details

Returns:

an artifact or null
