Getting com.google.cloud.datastore.DatastoreException: Unauthenticated Exception

[Omkar-Shetkar]

Hi,
I am learning GCP by following theses tutorials.

Tutorial: bookshelf/2-structured-data

To run this app locally:
mvn clean jetty:run-exploded

After, I am getting following exception.
com.google.cloud.datastore.DatastoreException: Unauthenticated.

According to procedure, I have enabled APIs and created OAuth 2 credentials.
Also, updated pom.xml with client ID and client secret details.

Please let me know if I am missing something here.

Thanks.

Canonical Error Code: UNAUTHENTICATED
Description: The com.google.cloud.datastore.DatastoreException simply indicates that the request did not have valid authentication credentials.
Recommended Action: Do not retry without fixing the problem. In this case you need to check the login credentials again.

More read can be found on this page https://cloud.google.com/datastore/docs/concepts/errors#error_codes

For me the fix was to do the login using below gcloud command

gcloud auth application-default login
