# Reference Homebrew formula for `amy`, the Amethyst CLI.
#
# This file is NOT consumed by any build in this repo. It is the artifact you
# submit to Homebrew/homebrew-core (`brew bump-formula-pr` / a new-formula PR).
# Once accepted, homebrew-core's copy is the source of truth; keep this in sync
# for reference and to make version bumps a copy-paste.
#
# Why a pre-built jar bundle instead of building from source:
#   homebrew-core builds inside a network sandbox, so a Gradle build cannot
#   resolve its Maven dependencies there. The accepted pattern for JVM tools is
#   to download a pre-built, no-JRE jar bundle and depend on the system openjdk.
#   We publish exactly that as `amy-<version>-jvm.tar.gz` (bin/amy + lib/*.jar,
#   no bundled runtime) from .github/workflows/create-release.yml.
#
# Before submitting: replace the version in the url and the sha256 with the
# values for the actual published release asset:
#   curl -fsSL -o amy-jvm.tar.gz \
#     https://github.com/vitorpamplona/amethyst/releases/download/vX.Y.Z/amy-X.Y.Z-jvm.tar.gz
#   shasum -a 256 amy-jvm.tar.gz
