Credentials Example

The documentation for Application Default Credentials.

BigQuery bigquery = BigQueryOptions.getDefaultInstance().getService();

The client library looks for credentials using the following rules:

  1. GOOGLE_APPLICATION_CREDENTIALS environment variable, pointing to a service account key JSON file path.
  2. Cloud SDK credentials gcloud auth application-default login
  3. App Engine standard environment credentials.
  4. Compute Engine credentials.

You can override this behavior using setCredentials in BigQueryOptions.newBuilder() by adding setCredentials(Credentials credentials) from ServiceOptions.builder and Credentials.
