# Fallback only — see go-Dockerfile's header comment for the general
# rule, including the Harbor base-images sourcing (also applies here).
# Simplified from the real java-Dockerfile: no JFrog artifact
# resolution, no Homelab-internal Maven mirror. Assumes a standard Maven
# repo producing a single runnable jar under target/. Switched both
# stages from their Debian defaults to the -alpine variant — smaller,
# still keeps a shell (not distroless). Maven itself still reaches out
# to Maven Central for plugins/dependencies during the build regardless
# of base image — this only removes the Docker Hub dependency for the
# base image layer, not package-registry traffic during the build.
