Method Details

initService

public void initService(ServiceLocator locator)

Description copied from interface: Service

Provides the opportunity to initialize this service and to acquire other services for its operation from the locator. A service must not save the reference to the provided service locator.

Specified by:

initService in interface Service

Parameters:

locator - The service locator, must not be null.

setRemoteRepositoryManager

public DefaultDependencyCollector setRemoteRepositoryManager(RemoteRepositoryManager remoteRepositoryManager)

setArtifactDescriptorReader

public DefaultDependencyCollector setArtifactDescriptorReader(ArtifactDescriptorReader artifactDescriptorReader)

setVersionRangeResolver

public DefaultDependencyCollector setVersionRangeResolver(VersionRangeResolver versionRangeResolver)

collectDependencies

public CollectResult collectDependencies(RepositorySystemSession session,
 CollectRequest request)
                                  throws DependencyCollectionException

Description copied from interface: DependencyCollector

Collects the transitive dependencies of some artifacts and builds a dependency graph. Note that this operation is only concerned about determining the coordinates of the transitive dependencies and does not actually resolve the artifact files. The supplied session carries various hooks to customize the dependency graph that must be invoked throughout the operation.

Specified by:

collectDependencies in interface DependencyCollector

Parameters:

session - The repository session, must not be null.

request - The collection request, must not be null.

Returns:

The collection result, never null.

Throws:

DependencyCollectionException - If the dependency tree could not be built.
