Error: "/app does not appear to be part of a Grails application" while using docker compose up --build

Hi

The command docker compose up --build ends with error message: /app does not appear to be part of a Grails application and exited with code 255.

Here I have attached the full logfile. Compose Build.log

Maybe someone knows, how to solve this issue?

If further information are needed, please let me know.
