When trying to start my Spring Boot application, I get google credentials needed even though I set them

Question

Right now, I have a spring boot application built with Maven. In IntelliJ, I'll run it and it will give me this error log. The last error says The Application Default Credentials are not available. They are available if running in Google Compute Engine. Otherwise, the environment variable GOOGLE_APPLICATION_CREDENTIALS must be defined pointing to a file defining the credentials. But I do have them. In my environment variables, I have GOOGLE_APPLICATION_CREDENTIALS pointing to the path of my credentials.json.

Answer 1

If you use Intellij then open menu: Run/Edit Configurations. In the new panel, on left column click + to add Spring Boot application if you don't have one. When you have your Spring Boot Application on left column, on the right, click on Configuration Tab, look for Environment, expand it. Look for Environment variables, click edit icon on the right and add GOOGLE_APPLICATION_CREDENTIALS and path to it. Save and run your application again. This will do the job. If you build jar and run with java -jar, you must export GOOGLE_APPLICATION_CREDENTIALS="path/to/key.json". Another approach: You also can set system-wide environment variables both on Mac and Windows to solve this issue.

Answer 2

Instead of using a service key file and the environment variable GOOGLE_APPLICATION_CREDENTIALS, you can also run the following command:

gcloud auth application-default login

You can then grant the access in the browser and the credentials will be saved in a file called application_default_credentials.json somewhere in your home directory.

The application will look for these credentials automatically if GOOGLE_APPLICATION_CREDENTIALS is not set. In most cases, this is the simpler approach.
