Usage:
  build.sh --from-local-dist [--archive <archive>] [--image-name <image>] [--build-multi-platform <comma-separated platforms>]
  build.sh --from-release --activemq-version <x.x.x> [--image-name <image>] [--build-multi-platform <comma-separated platforms>]
  build.sh --help

  If the --image-name flag is not used the built image name will be 'activemq'.
  Check the supported build platforms; you can verify with this command: docker buildx ls
  The supported platforms (OS/Arch) depend on the build's base image, in this case [eclipse-temurin:17-jre](https://hub.docker.com/_/eclipse-temurin).
