Two consecutive client_scripts errors traced to jei_hides.js: 1. Array-spread syntax not supported by Rhino (fixed in 0.21.1) 2. JEIEvents global is not defined in KubeJS 2101.7 -- the actual JEI event API uses classes like JEIRemoveEntriesKubeEvent but the binding name is something different we haven't identified yet. Rather than ship more guesses, drop the script entirely. Functional impact is minimal: recipes for waystones + coins are still removed server-side (recipes_waystones.js, recipes_numismatics.js), so players cannot craft these items even if they appear in JEI search. The only loss is some JEI clutter. When we identify the correct JEI hide API in KubeJS 2101.x, can add back as kubejs/client_scripts/jei_hides.js with the right binding.
Brass & Sigil
Self-hosted Minecraft modpack distribution + administration system. Three components, one repo:
brass-and-sigil/
├── launcher/ ← Avalonia desktop client (Windows .NET 8)
│ Auths with Microsoft, syncs the modpack, launches the game.
├── server/ ← brass-sigil-server daemon (Linux .NET 8)
│ Wraps the MC subprocess, exposes the admin web panel,
│ syncs mods, runs backups + BlueMap, handles whitelist.
├── pack/ ← Modpack content
│ ├── pack.lock.json Source of truth for mod versions / URLs / hashes
│ ├── tweaks/ Hand-written data-only tweak source
│ └── overrides/ Build output / hand-placed local files (gitignored)
├── scripts/ ← Build + deploy entry points (run from repo root)
│ ├── Update-Pack.ps1 Refresh pack.lock.json from Modrinth/CurseForge
│ ├── Check-Updates.ps1 Non-mutating "what's new?" report
│ ├── Build-Tweaks.ps1 Compile tweaks/ into pack/overrides/mods/*.jar
│ ├── Build-Pack.ps1 Generate manifest.json from the lockfile
│ └── Deploy-Brass.ps1 One-shot build + deploy everything
└── docs/ ← Operational notes, deploy runbook, schema docs
Quick start
# Pull dependencies, copy and edit the deploy profile
git clone <remote> brass-and-sigil
cd brass-and-sigil
Copy-Item scripts\deploy.config.template.ps1 scripts\deploy.config.ps1
notepad scripts\deploy.config.ps1 # fill in deploy share, SSH host, etc.
# Build + deploy everything in one go
.\scripts\Deploy-Brass.ps1
deploy.config.ps1 is gitignored -- local values never get committed.
Component reference
| Component | What it does | Technology |
|---|---|---|
launcher/ |
Friend-distributed client. Auths with Microsoft via WebView2 + XboxAuthNet, downloads mods, launches Minecraft. Single self-contained .exe published from publish/. |
Avalonia 12 + CmlLib.Core |
server/ |
Daemon running alongside the MC process on Linux. Hosts a Kestrel web panel for admin (cookie-auth, rate-limited), bridges RCON, runs scheduled backups + BlueMap renders, handles whitelist requests. | ASP.NET Core minimal APIs |
pack/ |
Lockfile-driven modpack content. pack.lock.json resolves mod slug → URL+SHA-1; Build-Pack.ps1 walks it and produces manifest.json for the launcher and the server-tool to consume. |
PowerShell tooling |
Workflow
- Bump mod versions:
.\scripts\Update-Pack.ps1(queries Modrinth + manual CurseForge entries). - Sanity-check:
.\scripts\Check-Updates.ps1for a non-mutating availability report. - Edit tweaks under
pack/tweaks/<name>/if you're changing recipes / loot / etc. - Deploy:
.\scripts\Deploy-Brass.ps1-- builds launcher + server, regenerates manifest, mirrors everything to the deploy share, scp's the server binary.
