  I  use the  java server side sample then change the my  `project_id` variable in `com.google.firebase.quickstart.Messaging.java' . The following logs show in my project. I  don't know why.

I have generated my account-service.json file. My project is virtually same as the quick-java simple.

I also encountered the same problem, how did you solve it in the end?
