Google drive API URL changes

[Pradeep Kr Kaushal via StackOverflow]

The application is running on production server which access https://www.googleapi.com through a proxy server. So how to set the url instead of https://www.googleapi.com to http://www.googleapi.com:443.

The sample code what currently is being used is

    File dataStoreDir = new File(resourceDir, credentials);

    JsonFactory jacksonFactory = JacksonFactory.getDefaultInstance();

    //List<String> scopes = Arrays.asList(DriveScopes.DRIVE);
    List<String> scopes = Arrays.asList("http://www.googleapis.com/auth/drive:443");

    HttpTransport httpTransport = GoogleNetHttpTransport.newTrustedTransport();

    FileDataStoreFactory dataStoreFactory = new FileDataStoreFactory(dataStoreDir);


    String clientSecret = config.getClientSecret();

    InputStream in = new FileInputStream(new File(resourceDir, clientSecret));
    GoogleClientSecrets clientSecrets = GoogleClientSecrets.load(jacksonFactory, new InputStreamReader(in));


    // Build flow and trigger user authorization request.
    GoogleAuthorizationCodeFlow flow =
            new GoogleAuthorizationCodeFlow.Builder(
                    httpTransport, jacksonFactory, clientSecrets, scopes)
                    .setDataStoreFactory(dataStoreFactory)
                    .setAccessType("offline")
                    .setAuthorizationServerEncodedUrl("http://www.googleapis.com/auth/drive:443")
                    .build();
    Credential credential = new AuthorizationCodeInstalledApp(
            flow, new LocalServerReceiver()).authorize("user");

    logger.info("Credentials saved to " + dataStoreDir.getAbsolutePath());


    drive =  new Drive.Builder(
            httpTransport, jacksonFactory, credential)
            .setApplicationName(applicationName)
            .build();

How to change the url in above code? When I change the drive instance creation

drive =  new Drive.Builder(
                httpTransport, jacksonFactory, credential)
                .setApplicationName(applicationName).setRootUrl("http://www.googleapis.com:443/")
                .build();

Then it gives the error
