Modifier and Type	Method and Description
void	artifactResolved(org.eclipse.aether.RepositoryEvent event)
(package private) static boolean	isInScope(org.eclipse.aether.artifact.Artifact artifact, org.eclipse.aether.artifact.Artifact nodeArtifact) The event "artifact resolved" if fired WHENEVER an artifact is resolved, BUT it happens also when an artifact descriptor (model, the POM) is being built, and parent (and parent of parent...) is being asked for.
(package private) static boolean	isLocalRepositoryArtifact(org.eclipse.aether.RepositorySystemSession session, org.eclipse.aether.artifact.Artifact artifact) Returns true if passed in artifact is originating from local repository.
(package private) static org.eclipse.aether.collection.CollectStepData	lookupCollectStepData(org.eclipse.aether.RequestTrace trace) Unravels trace tree (going upwards from current node), looking for CollectStepData trace data.

Method Detail

artifactResolved

public void artifactResolved(org.eclipse.aether.RepositoryEvent event)

Specified by:

artifactResolved in interface org.eclipse.aether.RepositoryListener

Overrides:

artifactResolved in class org.eclipse.aether.AbstractRepositoryListener

isLocalRepositoryArtifact

static boolean isLocalRepositoryArtifact(org.eclipse.aether.RepositorySystemSession session,
                                         org.eclipse.aether.artifact.Artifact artifact)

Returns true if passed in artifact is originating from local repository. In other words, we want to process and store tracking information ONLY into local repository, not to any other place. This method filters out currently built artifacts, as events are fired for them as well, but their resolved artifact file would point to checked out source-tree, not the local repository.

Visible for testing.

lookupCollectStepData

static org.eclipse.aether.collection.CollectStepData lookupCollectStepData(org.eclipse.aether.RequestTrace trace)

Unravels trace tree (going upwards from current node), looking for CollectStepData trace data. This method may return null if no collect step data found in passed trace data or it's parents.

Visible for testing.

isInScope

static boolean isInScope(org.eclipse.aether.artifact.Artifact artifact,
                         org.eclipse.aether.artifact.Artifact nodeArtifact)

The event "artifact resolved" if fired WHENEVER an artifact is resolved, BUT it happens also when an artifact descriptor (model, the POM) is being built, and parent (and parent of parent...) is being asked for. Hence, this method "filters" out in WHICH artifact are we interested in, but it intentionally neglects extension as ArtifactDescriptorReader modifies extension to "pom" during collect. So all we have to rely on is GAV only.
