/**
 * Google-specific implementation of the OAuth 2.0 request for an access token based on an
 * authorization code (as specified in <a
 * href="https://developers.google.com/identity/protocols/OAuth2WebServer">Using OAuth 2.0 for Web
 * Server Applications</a>).
 *
 * <p>
 * Use {@link GoogleCredential} to access protected resources from the resource server using the
 * {@link TokenResponse} returned by {@link #execute()}. On error, it will instead throw
 * {@link TokenResponseException}.
 * </p>
 *
 * <p>
 * Sample usage:
