/**
 * OAuth 2.0 request for an access token using an authorization code as specified in Access Token Request.
 *
 * 

 * Use {@link Credential} to access protected resources from the resource server using the
 * {@link TokenResponse} returned by {@link #execute()}. On error, it will instead throw
 * {@link TokenResponseException}.
 * 
 *
 * 

 * Sample usage:
 * 
 *
 * 
  static void requestAccessToken() throws IOException {
    try {
      TokenResponse response =
          new AuthorizationCodeTokenRequest(new NetHttpTransport(), new JacksonFactory(),
              new GenericUrl("https://server.example.com/token"), "SplxlOBeZQQYbYS6WxSbIA")
              .setRedirectUri("https://client.example.com/rd")
              .setClientAuthentication(
                  new BasicAuthentication("s6BhdRkqt3", "7Fjfp0ZBr1KtDRbnfVdmIw")).execute();
      System.out.println("Access token: " + response.getAccessToken());
    } catch (TokenResponseException e) {
      if (e.getDetails() != null) {
        System.err.println("Error: " + e.getDetails().getError());
        if (e.getDetails().getErrorDescription() != null) {
          System.err.println(e.getDetails().getErrorDescription());
        }
        if (e.getDetails().getErrorUri() != null) {
          System.err.println(e.getDetails().getErrorUri());
        }
      } else {
        System.err.println(e.getMessage());
      }
    }
  }
 * 
 *
 * 

 * Some OAuth 2.0 providers don't support {@link BasicAuthentication} but instead support
 * {@link ClientParametersAuthentication}. In the above sample code, simply replace the class name
 * and it will work the same way.
 * 
 *
 * 

 * Implementation is not thread-safe.
