                                        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.

collectStepTrace

protected RequestTrace collectStepTrace(RequestTrace trace,
 String context,
 List<DependencyNode> path,
 Dependency node)

Creates child RequestTrace instance from passed in RequestTrace and parameters by creating CollectStepDataImpl instance out of passed in data. Caller must ensure that passed in parameters are NOT affected by threading (or that there is no multi threading involved). In other words, the passed in values should be immutable.

Parameters:

trace - The current trace instance.

context - The context from CollectRequest.getRequestContext(), never null.

path - List representing the path of dependency nodes, never null. Caller must ensure, that this list does not change during the lifetime of the requested RequestTrace instance. If it may change, simplest is to pass here a copy of used list.

node - Currently collected node, that collector came by following the passed in path.

Returns:

A child request trance instance, never null.
