To use

 GoogleCredentials credentials = GoogleCredentials.getApplicationDefault()

You must have the environment variable GOOGLE_APPLICATION_CREDENTIALS must be defined pointing to a file defining the credentials.

Other wise you can do it like shown in the Google drive java quickstart

private static final String CREDENTIALS_FILE_PATH = "/credentials.json";

InputStream in = DriveQuickstart.class.getResourceAsStream(CREDENTIALS_FILE_PATH);
if (in == null) {
  throw new FileNotFoundException("Resource not found: " + CREDENTIALS_FILE_PATH);
}
GoogleClientSecrets clientSecrets =
    GoogleClientSecrets.load(JSON_FACTORY, new InputStreamReader(in));
