# Real Minecraft servers for live-testing the mod against a running MCMapper-Backend stack —
# see README.md in this directory for the full walkthrough (build the mod, seed a backend server
# token, drop the jar in mods/<loader>/<version>/, docker compose up). Mods are split by loader
# first, then version — Forge and NeoForge mod jars aren't interchangeable even for adjacent MC
# versions, and a future Fabric leaf (Phase 14) would add its own mods/fabric/<version> alongside
# these rather than needing a reshuffle.
#
# Uses itzg/docker-minecraft-server (https://github.com/itzg/docker-minecraft-server, MIT) — the
# de facto standard MC server image, handles EULA/Forge/NeoForge installation, memory flags, etc.
# so this compose file doesn't have to reimplement any of that.
#
# Only `mc-1_12_2` (the actual driving use case — Enigmatica 2, see the plan's version priority)
# runs by default. The other two leaves are opt-in via Compose profiles, since running all three
# at once is a lot of RAM for a local dev box:
#   docker compose up                          # 1.12.2 only (default)
#   docker compose --profile legacy-1_7_10 up   # + 1.7.10
#   docker compose --profile neoforge-26_1 up   # + 26.1.2 (NeoForge) — least tested, lowest MVP priority

    # JDK 8 constraint as this repo's own build toolchain (see ../gradle.properties), just for the
