I cannot run a spring-boot web image built with Paketo Buildpacks by spring-maven-plugin. Error says:
Deploying container to Cloud Run service [bff] in project [merchantloans] region [us-central1]
X Deploying...
- Creating Revision...
. Routing traffic...
Deployment failed
ERROR: (gcloud.run.deploy) Revision 'bff-00002-wtm' is not ready and cannot serve traffic. The user-provided container failed to start and listen on the port defined provided by the PORT=8080 environment variable. Logs for this revision might contain more information.
Any ideas? Even if I try to set PORT=8080 environment variable in local docker it doesn't expose port 8080. Only if I use the docker -p argument does that work, but that doesn't seem to be available in google-cloud-run

You're on the right track! Using the pack CLI and setting the port argument during the build is a good approach to ensure your Spring Boot web image listens on the correct port for Google Cloud Run.
Steps:
pack CLI:pack build my-spring-boot-app:latest --env PORT=8080
Replace my-spring-boot-app:latest with your application name and tag.
This sets the PORT environment variable to 8080 within the container image.
Push the built image to your container registry.
Deploy the image to Cloud Run using gcloud run deploy:
gcloud run deploy SERVICE_NAME --image REGISTRY_URL/my-spring-boot-app:latest
This approach ensures your application listens on the expected port (8080) for Cloud Run.
