I'm trying to generate models for Cert-Manager CRD.

I followed the documentation here

I'm generating on local environment.

These are some last few lines of logs before the process exits.

--- Running generator inside container...
docker: Error response from daemon: OCI runtime create failed: container_linux.go:380: starting container process caused: exec: "mvn-entrypoint.sh": executable file not found in $PATH: unknown.
ERRO[0000] error waiting for container: context canceled

I tried to debug on my own and found that this container doesn't seem to have maven installed. I also tried this locally and got the same error.

Not sure if I'm doing something wrong or the container is broken.
