        public ConflictResolver.ScopeDeriver getInstance​(org.eclipse.aether.graph.DependencyNode root,
                                                         org.eclipse.aether.collection.DependencyGraphTransformationContext context)
                                                  throws org.eclipse.aether.RepositoryException
        Retrieves the scope deriver for use during the specified graph transformation. The conflict resolver calls this method once per ConflictResolver.transformGraph(DependencyNode, DependencyGraphTransformationContext) invocation to allow implementations to prepare any auxiliary data that is needed for their operation. Given that implementations must be stateless, a new instance needs to be returned to hold such auxiliary data. The default implementation simply returns the current instance which is appropriate for implementations which do not require auxiliary data.
        Parameters:
        root - The root node of the (possibly cyclic!) graph to transform, must not be null.
        context - The graph transformation context, must not be null.
        Returns:
        The scope deriver to use for the given graph transformation, never null.
        Throws:
        org.eclipse.aether.RepositoryException - If the instance could not be retrieved.
      • deriveScope

        public abstract void deriveScope​(ConflictResolver.ScopeContext context)
                                  throws org.eclipse.aether.RepositoryException
        Determines the scope of a dependency in relation to the scope of its parent. Implementors need to call ConflictResolver.ScopeContext.setDerivedScope(String) to deliver the result of their calculation. If said method is not invoked, the conflict resolver will assume the scope of the child dependency remains unchanged.
        Parameters:
        context - The scope context, must not be null.
        Throws:
        org.eclipse.aether.RepositoryException - If the scope deriviation failed.
