/**
 * Creates enhanced local repository managers for repository types {@code "default"} or {@code "" (automatic)}.
 * Enhanced local repository manager is built upon the classical Maven 2.0 local repository structure but additionally keeps
 * track of from what repositories a cached artifact was resolved.
 * Resolution of locally cached artifacts will be rejected in case the current resolution request does not match the
 * known source repositories of an artifact, thereby emulating physically separated artifact caches per remote repository.
