 * Integration test intended to deploy the plugin within Nexus Repository manager in a GCP project configured
 * to use Firestore in Native mode. We expect this to fail; we require the project to use Firestore in Datastore mode.
 * Depends on:
 * <ul>
 *   <li>GOOGLE_FIRESTORE_CREDENTIALS being present in your Environment</li>
 *   <li>GOOGLE_FIRESTORE_CREDENTIALS pointing to a service account key file for a project using Firestore in Native mode</li>
 *   <li>The service account has the storage admin account</li>
 * </ul>
 * The last step is needed as the bucket is created first, then the datastore backed entities.
