[ERROR] 

Indeed trying to fetch the mentioned docker image by hand results in a 403 error from gcr.io:

% docker pull gcr.io/paketo-buildpacks/builder/base-platform-api-0.3
Using default tag: latest
Error response from daemon: Head "https://gcr.io/v2/paketo-buildpacks/builder/base-platform-api-0.3/manifests/latest": denied: Caller does not have permission or the resource may not exist 'read'. To configure permissions, follow instructions at: https://cloud.google.com/container-registry/docs/access-control

Trying to figure out why, I stumbled upon this blogpost: https://blog.paketo.io/posts/paketo-gcr-registry-sunset/. I tried to bump to the last version of the 2.3.x spring boot version (2.3.12) but with no luck. As stated in the blogpost, there may be a way to configure the spring boot maven plugin so that it gets the image from docker-hub instead, but I have not been further yet.
