  /**
   * Execution Listener demo.<br>
   * <b>Question:</b> how to instantiate and inject it to Maven runtime?<br>
   * <b>Answer</b>: LifecycleParticipant (injected by Plexus/Sisu) can get original ExecutionListener from
   * request and replace with this class that should delegate to original listener<br>
   * <b>Example</b>: Maven's <a href=
   * "https://maven.apache.org/ref/current/maven-embedder/xref/org/apache/maven/cli/MavenCli.html#L1446">CLI</a> creates
   * a new instance of
   * <a href=
   * "https://maven.apache.org/ref/current/maven-embedder/apidocs/org/apache/maven/cli/event/ExecutionEventLogger.html"
   * >ExecutionEventLogger</a> that displays to console, and calls
   * {@code eventSpyDispatcher.chainListener(executionListener)}.
   *
   * @see org.apache.maven.execution.MavenExecutionRequest#setExecutionListener(org.apache.maven.execution.ExecutionListener)
