/**
 * TCK test class checking that an excluded transitive dependency of another transitive dependency of a project is not
 * included when running generatečPOM() method. The dependency graph looks like this:
 * <pre>
 *   +----------+
 *   | consumer |
 *   +----------+
 *        |
 *        | depends on
 *        V
 *   +---------+
 *   |   dep   |
 *   +---------+
 *        |
 *        | depends on with exclusion of excluded-dep
 *        V
 *   +----------------+  depends on  +--------------+
 *   | transitive-dep |------------->| excluded-dep |
 *   +----------------+              +--------------+
 * </pre>
 *
 * The {@code consumer} is used as the request root artifact. Used preset is "requires", which results in usage of
 * {@link ScopeWithEmbeddedProjectsFilter} with scope runtime, i.e. runtime dependency graph. Consumer pom, dep jar
 * and transitive-dep jar are expected to be in the result.
