GoogleCredentials credentials =
    ServiceAccountCredentials.getApplicationDefault()
        .createScoped(
            ImmutableSet.of(
                "https://www.googleapis.com/auth/bigquery",
                "https://www.googleapis.com/auth/drive"));

// Initialize client that will be used to send requests. This client only needs to be created
// once, and can be reused for multiple requests.
BigQuery bigquery =
    BigQueryOptions.newBuilder().setCredentials(credentials).build().getService();
