Terraform example for google app engine standard Java8

Terraform Providers Google

Hi all. I wonder if there’s any knowledge / examples on how to deploy a google app engine service to the standard environment for java 8
https://registry.terraform.io/providers/hashicorp/google/latest/docs/resources/app_engine_standard_app_version
The documents only suggest how to do it for a node application.
I presume you’d have to specify a war or jar file somewhere in the entrypoint?

Thanks!
