 * Verifies scope inheritance of direct and transitive dependencies.

 *
 * 1. dependencyManagement should override the scope of transitive dependencies.
 * 2. Direct dependencies should override the scope of dependencyManagement.
 * 3. Direct dependencies should inherit scope from dependencyManagement when
 *    they do not explicitly state a scope.
