  org.sonatype.aether.util.graph.transformer.JavaEffectiveScopeCalculator

All Implemented Interfaces:

DependencyGraphTransformer

public class JavaEffectiveScopeCalculator
extends java.lang.Object
implements DependencyGraphTransformer

A dependency graph transformer that handles scope inheritance and conflict resolution among conflicting scopes as seen in Maven 2.x. For a given set of conflicting nodes, a single scope will be chosen and assigned to all of the nodes. This transformer will query the keys TransformationContextKeys.CONFLICT_IDS and TransformationContextKeys.SORTED_CONFLICT_IDS for existing information about conflict ids. In absence of this information, it will automatically invoke the ConflictIdSorter to calculate it.
