collect

@Nonnull
public DependencyResolverResult collect(@Nonnull
 DependencyResolverRequest request)
                                 throws DependencyResolverException,
IllegalArgumentException

Description copied from interface: DependencyResolver

Collects the transitive dependencies 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.

Specified by:

collect in interface DependencyResolver

Parameters:

request - the dependency collection request, must not be null

Returns:

the collection result, never null

Throws:

DependencyResolverException - if the dependency tree could not be built

IllegalArgumentException - if an argument is null or invalid

• DependencyResolver.collect(Session, DependencyCoordinates, PathScope)

flatten

@Nonnull
public List<Node> flatten(@Nonnull
 Session s,
 @Nonnull
 Node node,
 @Nullable
 PathScope scope)
                   throws DependencyResolverException

Description copied from interface: DependencyResolver

Flattens a list of nodes. Note that the PathScope argument should usually be null as the dependency tree has been filtered during collection for the appropriate scope.

Specified by:

flatten in interface DependencyResolver

Parameters:

s - the Session, must not be null

node - the Node to flatten, must not be null

scope - an optional PathScope to filter out dependencies

Returns:

the flattened list of node

Throws:

DependencyResolverException

resolve

public DependencyResolverResult resolve(DependencyResolverRequest request)
                                 throws DependencyResolverException,
ArtifactResolverException

Collects, flattens and resolves the dependencies.

Specified by:

resolve in interface DependencyResolver

Parameters:

request - the request to resolve

Returns:

the result of the resolution

Throws:

DependencyResolverException

ArtifactResolverException
