Java development experience and needs to learn everything from scratch.

Guide covers (1,700+ lines):
- What Java/JDK/IDE/Gradle/NeoForge are (plain English)
- Installing Java 21 JDK (Windows/Mac/Linux)
- Installing IntelliJ IDEA Community Edition
- Creating project structure from scratch
- Understanding folder organization (src/main/java, package names)
- Copy/paste all 10 files (3 build + 1 metadata + 7 Java)
- Running Gradle build (first-time setup)
- Finding the compiled JAR
- Deploying to Pterodactyl server
- Configuring Discord (channel ID, message ID, bot token)
- Testing the /rules command
- Troubleshooting common errors (build failures, runtime issues)
- Holly's editing workflow
- Creating a Discord bot (appendix)

Accessibility features:
- Plain English explanations (no jargon without definition)
- Step-by-step with screenshots described
- Common errors with exact fixes
- Analogies for complex concepts
- Checkpoints after each phase

FILES CHANGED:
- docs/guides/firefrost-rules-mod-beginner-guide.md (new, 1,741 lines)

Firefrost Rules Mod — Complete Beginner's Guide

From Zero Experience to Working Minecraft Mod

For: Michael (or anyone with zero Java/modding experience)
Goal: Build and deploy the Firefrost Rules mod on your Minecraft server
Time: 2-4 hours (first time, including downloads and setup)
Difficulty: Beginner-friendly (we assume you know NOTHING)

🎯 What You're Building

You're creating a Minecraft server mod that:

  • Adds a /rules command players can type in-game
  • Fetches the rules from a Discord message (so Holly can edit them easily)
  • Displays the rules in chat with pretty Fire/Frost/Arcane colors
  • Works on all your Minecraft 1.21.1 NeoForge servers

Why this is cool:

  • Holly never needs to SSH into a server or edit files
  • She just right-clicks a Discord message, edits it, and saves
  • Next time someone types /rules in-game, they see the updated version
  • Zero server downtime, zero technical knowledge needed

🧠 Understanding the Basics

Before we start, let's demystify what everything is:

What is Java?

Java is a programming language. Minecraft is written in Java, so mods are also written in Java.

Think of it like: if Minecraft speaks Spanish, mods need to speak Spanish too. Java is that language.

What is a JDK?

JDK = Java Development Kit. It's the software that lets you write and compile Java code.

Analogy: If Java is Spanish, the JDK is the dictionary and grammar book you need to write in Spanish.

You need: Java 21 JDK (Minecraft 1.21.1 requires this specific version)

What is an IDE?

IDE = Integrated Development Environment. It's a fancy text editor made for writing code.

Analogy: You could write code in Notepad, but an IDE is like Microsoft Word for programmers — it highlights mistakes, auto-completes words, and makes everything easier.

We're using: IntelliJ IDEA Community Edition (free, industry standard for Minecraft mods)

What is Gradle?

Gradle is a build tool. It takes your Java code (which humans can read) and compiles it into a .jar file (which Minecraft can run).

Analogy: You write a recipe (Java code). Gradle bakes it into a cake (the mod file).

You don't need to install Gradle — it comes bundled with your project.

What is NeoForge?

NeoForge is the mod loader for Minecraft 1.21+. It's the framework that lets mods talk to Minecraft.

Analogy: Minecraft is a restaurant kitchen. NeoForge is the system that lets new cooks (mods) work in that kitchen without breaking everything.

What is a .jar file?

JAR = Java Archive. It's a zip file containing compiled Java code.

When you "build" the mod, Gradle creates a .jar file. You put that .jar file in your server's mods/ folder, and Minecraft loads it.


Prerequisites Check

Before you start, make sure you have:

  1. A computer (Windows, Mac, or Linux — all work)
  2. Administrator access (you'll need to install software)
  3. Internet connection (to download Java, IntelliJ, etc.)
  4. At least 4GB free disk space (for tools + project)
  5. A Minecraft 1.21.1 NeoForge server (running and accessible)
  6. Discord bot token (from The Arbiter, or create a new bot)
  7. Patience (first time takes longer, but you'll learn!)

Time you'll need:

  • Software installation: 30-60 minutes
  • Project setup: 15-30 minutes
  • Building the mod: 10-15 minutes
  • Testing: 15-30 minutes
  • Total: 2-4 hours

📥 Phase 1: Installing Software

We need to install 2 things: Java 21 and IntelliJ IDEA.

Step 1.1: Install Java 21 JDK

Windows:

  1. Download Java 21:

  2. Install:

    • Run the downloaded .msi file
    • Click "Next" through the installer
    • IMPORTANT: Check the box that says "Set JAVA_HOME variable"
    • IMPORTANT: Check the box that says "Add to PATH"
    • Click "Install"
    • Wait for it to finish
  3. Verify it worked:

    • Open Command Prompt (press Win+R, type cmd, press Enter)
    • Type: java -version
    • You should see something like: openjdk version "21.0.x"
    • If you see this, Java is installed!

Mac:

  1. Download Java 21:

  2. Install:

    • Run the downloaded .pkg file
    • Follow the installer prompts
    • Enter your password when asked
  3. Verify it worked:

    • Open Terminal (Cmd+Space, type "Terminal", press Enter)
    • Type: java -version
    • You should see: openjdk version "21.0.x"
    • If you see this, Java is installed!

Linux (Ubuntu/Debian):

sudo apt update
sudo apt install openjdk-21-jdk
java -version

You should see: openjdk version "21.0.x"


Step 1.2: Install IntelliJ IDEA Community Edition

Windows:

  1. Download IntelliJ:

  2. Install:

    • Run the downloaded .exe file
    • Click "Next" through the installer
    • IMPORTANT: Check these boxes:
      • "Create Desktop Shortcut"
      • "Add 'Open Folder as Project'"
      • "Add launchers dir to PATH"
    • Click "Install"
    • Restart your computer when it finishes

Mac:

  1. Download IntelliJ:

  2. Install:

    • Open the downloaded .dmg file
    • Drag "IntelliJ IDEA CE" to your Applications folder
    • Open IntelliJ from Applications

Linux:

Option A: Snap (easiest):

sudo snap install intellij-idea-community --classic

Option B: Manual:


Step 1.3: First-Time IntelliJ Setup

  1. Open IntelliJ IDEA

    • First time you open it, it'll ask some questions
  2. Theme:

    • Choose Dark or Light theme (personal preference)
    • Click "Next"
  3. Plugins:

    • It'll suggest plugins — click "Skip Remaining and Set Defaults"
    • (We don't need extra plugins for this project)
  4. Welcome Screen:

    • You should see "Welcome to IntelliJ IDEA"
    • Leave this open — we'll use it in Phase 2

🏗️ Phase 2: Creating the Project

Now we create the folder structure for your mod.

Step 2.1: Create Project Directory

Option A: Using File Explorer (Windows):

  1. Open File Explorer
  2. Navigate to a location you'll remember (e.g., C:\Users\YourName\Documents\)
  3. Right-click → New → Folder
  4. Name it: FirefrostRules

Option B: Using Terminal (Mac/Linux):

cd ~/Documents
mkdir FirefrostRules
cd FirefrostRules

Write down this path — you'll need it in a minute.

Example:

  • Windows: C:\Users\Michael\Documents\FirefrostRules
  • Mac: /Users/michael/Documents/FirefrostRules
  • Linux: /home/michael/Documents/FirefrostRules

Step 2.2: Create Folder Structure

Inside FirefrostRules, we need to create this structure:

FirefrostRules/
├── src/
│   ├── main/
│   │   ├── java/
│   │   │   └── com/
│   │   │       └── firefrostgaming/
│   │   │           └── rules/
│   │   └── resources/
│   │       └── META-INF/

Windows (Command Prompt):

cd C:\Users\YourName\Documents\FirefrostRules
mkdir src\main\java\com\firefrostgaming\rules
mkdir src\main\resources\META-INF

Mac/Linux (Terminal):

cd ~/Documents/FirefrostRules
mkdir -p src/main/java/com/firefrostgaming/rules
mkdir -p src/main/resources/META-INF

Why these weird folder names?

  • src/main/java/ — where Java code lives
  • com/firefrostgaming/rules/ — your "package name" (like an address for your code)
  • src/main/resources/META-INF/ — where mod metadata lives

Step 2.3: Open Project in IntelliJ

  1. In IntelliJ's Welcome Screen:

    • Click Open
  2. Navigate to your project:

    • Find the FirefrostRules folder you just created
    • Select it
    • Click OK
  3. Trust the project:

    • IntelliJ will ask "Trust and Open Project?"
    • Click Trust Project
  4. Wait for indexing:

    • IntelliJ will spend 1-2 minutes "indexing" the project
    • You'll see a progress bar at the bottom
    • Wait for it to finish

📝 Phase 3: Adding the Code

Now we copy/paste all the files into the project.

Step 3.1: Create Build Files (Root Level)

These files go in the root of your project (the FirefrostRules folder itself).

File 1: gradle.properties

  1. In IntelliJ, right-click on FirefrostRules (the project root in the left panel)
  2. Click New → File
  3. Type: gradle.properties
  4. Press Enter
  5. Copy/paste this content:
org.gradle.jvmargs=-Xmx3G
org.gradle.daemon=false

# NeoForge 1.21.1 versions
minecraft_version=1.21.1
neo_version=21.1.61

mod_id=firefrostrules
mod_name=Firefrost Rules
mod_version=1.0.0
mod_group_id=com.firefrostgaming.rules
  1. Press Ctrl+S (Windows/Linux) or Cmd+S (Mac) to save

File 2: build.gradle

  1. Right-click on FirefrostRules again
  2. Click New → File
  3. Type: build.gradle
  4. Press Enter
  5. Copy/paste this content:
plugins {
    id 'java-library'
    id 'net.neoforged.moddev' version '2.0.74-beta'
}

version = mod_version
group = mod_group_id

repositories {
    mavenCentral()
}

dependencies {
}

neoForge {
    version = neo_version
    
    runs {
        server {
            server()
            systemProperty 'neoforge.enableGameTest', 'true'
            systemProperty 'neoforge.showVulnerabilities', 'true'
        }
    }

    mods {
        "${mod_id}" {
            sourceSet sourceSets.main
        }
    }
}

tasks.withType(JavaCompile).configureEach {
    options.encoding = 'UTF-8'
    options.release.set(21)
}
  1. Save (Ctrl+S / Cmd+S)

File 3: settings.gradle

  1. Right-click on FirefrostRules again
  2. Click New → File
  3. Type: settings.gradle
  4. Press Enter
  5. Copy/paste this content:
pluginManagement {
    repositories {
        mavenCentral()
        gradlePluginPortal()
        maven { url = 'https://maven.neoforged.net/releases' }
    }
}

rootProject.name = 'firefrostrules'
  1. Save (Ctrl+S / Cmd+S)

Step 3.2: Create Mod Metadata File

This file goes in src/main/resources/META-INF/

  1. In IntelliJ's left panel, expand: src → main → resources → META-INF
  2. Right-click on META-INF
  3. Click New → File
  4. Type: neoforge.mods.toml
  5. Press Enter
  6. Copy/paste this content:
modLoader="javafml"
loaderVersion="[21,)"
license="All Rights Reserved"
issueTrackerURL="https://firefrostgaming.com/support"
showAsResourcePack=false

[[mods]]
modId="firefrostrules"
version="${file.jarVersion}"
displayName="Firefrost Rules"
displayURL="https://firefrostgaming.com"
authors="Firefrost Gaming"
description='''

Built for long-term stability and easy community management.
'''

[[dependencies.firefrostrules]]
modId="neoforge"
type="required"
versionRange="[21.1.61,)"
ordering="NONE"
side="SERVER"

[[dependencies.firefrostrules]]
modId="minecraft"
type="required"
versionRange="[1.21.1,1.22)"
ordering="NONE"
side="SERVER"
  1. Save (Ctrl+S / Cmd+S)

Step 3.3: Create Java Files

Now we create the 7 Java classes. These all go in: src/main/java/com/firefrostgaming/rules/

For each file below:

  1. Right-click on the rules folder
  2. Click New → Java Class
  3. Type the class name (e.g., ServerRules)
  4. Press Enter
  5. Delete everything IntelliJ auto-generated
  6. Copy/paste the full code from below

                })
        );
    }
}

Step 3.4: Let IntelliJ Load Gradle

  1. You should see a notification at the top-right saying "Gradle build scripts found"

  2. Click Load Gradle Project

  3. Wait (this takes 5-10 minutes the first time)

    • IntelliJ is downloading NeoForge and all dependencies
    • You'll see a progress bar
    • Be patient — this is normal
  4. When it's done:

    • The progress bar disappears
    • You see a "Build" tab at the bottom
    • No error messages (if you see errors, see Troubleshooting section)

🔨 Phase 4: Building the Mod

Time to compile the code into a .jar file.

Step 4.1: Open Gradle Panel

  1. Look at the right side of IntelliJ
  2. Click the Gradle tab (vertical text on the right edge)
  3. The Gradle panel opens
  4. Expand: FirefrostRules → Tasks → build

Step 4.2: Run the Build

  1. Double-click on build
  2. A "Run" panel opens at the bottom
  3. You'll see lots of text scrolling
  4. Wait (first build takes 3-5 minutes)

What you're looking for:

  • At the end, you should see: BUILD SUCCESSFUL
  • Total time will show (e.g., BUILD SUCCESSFUL in 3m 24s)

If you see BUILD FAILED:

  • Go to the Troubleshooting section
  • Read the error message carefully
  • Common issues are listed there

Step 4.3: Find Your JAR File

  1. In IntelliJ's left panel, expand: build → libs
  2. You should see: firefrostrules-1.0.0.jar
  3. Right-click on it
  4. Click Show in Explorer (Windows) or Reveal in Finder (Mac)
  5. This is your mod! 🎉

File location: FirefrostRules/build/libs/firefrostrules-1.0.0.jar


🧪 Phase 5: Testing Locally

Before deploying to production, test it locally.

Option A: Test on Your Pterodactyl Server

If you have a test/dev server:

  1. Upload the JAR:

    • Go to your Pterodactyl panel
    • Navigate to your test server's Files
    • Go to the mods/ folder
    • Upload firefrostrules-1.0.0.jar
  2. Start the server

  3. Check logs for: Firefrost Rules Mod Initialized

  4. Join the server

  5. Type: /rules

  6. You should see: Fallback rules (since Discord isn't configured yet)

Option B: Skip Local Testing

If you don't have a test server, you can deploy directly to production (we'll configure Discord first).


🚀 Phase 6: Deploying to Server

Step 6.1: Upload to Production Server

Via Pterodactyl Panel:

  1. Log into your Pterodactyl panel
  2. Select your Minecraft server
  3. Go to Files
  4. Navigate to mods/ folder
  5. Click Upload
  6. Select firefrostrules-1.0.0.jar
  7. Wait for upload to complete

Via SFTP (if you prefer):

scp FirefrostRules/build/libs/firefrostrules-1.0.0.jar user@your-server:/path/to/mods/

Step 6.2: Restart Server

  1. In Pterodactyl, click Console
  2. Type: stop
  3. Wait for server to shut down
  4. Click Start
  5. Watch the console logs

What to look for:

  • [firefrostrules]: Firefrost Rules Mod Initialized
  • [firefrostrules]: Registered /rules command

If you see these, the mod loaded!


🔧 Phase 7: Configuring Discord

The mod is installed, but it doesn't know where to get rules yet.

Step 7.1: Create Discord Rules Channel

  1. In your Discord server:

    • Create a channel called #server-rules (or use existing)
    • Make it read-only for @everyone
    • Only staff can post
  2. Post your rules:

    • Write your rules in a message
    • You can use Discord markdown:
      • **Bold** for headers
      • - Bullet points
      • Emojis: 🔥 ❄️ 💜 (these auto-convert)

Example rules message:

**🔥 FIREFROST GAMING — SERVER RULES**

**Community & Respect**
- Be kind and welcoming to all players
- No harassment, hate speech, or discrimination
- Keep chat appropriate for all ages

**Gameplay**
- No griefing, stealing, or intentional destruction
- No cheating, hacking, or exploiting bugs
- Respect server resources (no lag machines)

**The Foundation**
- Follow staff instructions
- Report issues via Discord ticket system
- Have fun and build something amazing!

Step 7.2: Get Channel ID and Message ID

Enable Developer Mode:

  1. Discord → User Settings (gear icon)
  2. Advanced
  3. Enable Developer Mode
  4. Close settings

Get Channel ID:

  1. Right-click on #server-rules channel
  2. Click Copy Channel ID
  3. Paste somewhere safe (e.g., Notepad)
    • Example: 1260574715546701936

Get Message ID:

  1. Right-click on your rules message
  2. Click Copy Message ID
  3. Paste somewhere safe
    • Example: 1234567890123456789

Get Bot Token:

  • Use The Arbiter's bot token (you already have this)
  • OR create a new Discord bot (see "Creating a Discord Bot" below)

Step 7.3: Edit Config File

  1. On your server, find the config:

    • Path: config/firefrostrules-server.toml
    • (This file is created the first time the server starts with the mod)
  2. Stop your server (to edit the config)

  3. Edit the file:

[discord]
bot_token = "YOUR_ARBITER_BOT_TOKEN_HERE"
channel_id = "1260574715546701936"  # Your channel ID
message_id = "1234567890123456789"  # Your message ID

[performance]
cooldown_seconds = 60
cache_minutes = 30

Replace:

  • YOUR_ARBITER_BOT_TOKEN_HERE with your actual bot token
  • 1260574715546701936 with your actual channel ID
  • 1234567890123456789 with your actual message ID
  1. Save the file

  2. Start your server

Step 7.4: Test It!

  1. Join your Minecraft server
  2. Type: /rules
  3. You should see:
    • "Fetching latest rules..." (brief message)
    • Then your rules from Discord, formatted in Fire/Frost/Arcane colors!

If it works: 🎉 YOU'RE DONE!


🛠️ Troubleshooting

Common Build Errors

Error: "Java version mismatch"

Symptom: Gradle fails with "Java 21 required" Fix:

  1. Verify Java 21 is installed: java -version
  2. In IntelliJ: File → Project Structure → Project → SDK → Select Java 21
  3. Re-run build

Error: "Cannot resolve symbol"

Symptom: Red underlines in code, imports don't work Fix:

  1. File → Invalidate Caches → Invalidate and Restart
  2. Wait for IntelliJ to re-index
  3. Re-run Gradle: Gradle panel → Reload All Gradle Projects

Error: "BUILD FAILED" with cryptic Gradle errors

Fix:

  1. Check your internet connection (Gradle needs to download dependencies)
  2. Delete .gradle folder in your project root
  3. Re-run build

Common Runtime Errors

"/rules command not found"

Cause: Mod didn't load Fix:

  1. Check server logs for: Firefrost Rules Mod Initialized
  2. If not found, mod isn't in mods/ folder
  3. Re-upload the JAR

"Invalid Discord Message ID"

Cause: Config has wrong message ID format Fix:

  1. Message IDs are 17-20 digits
  2. Check you copied the full ID (no spaces)
  3. Verify with: https://discordlookup.com/message-id

"Discord API returned status: 401"

Cause: Bot token is invalid Fix:

  1. Verify token is correct
  2. Regenerate token in Discord Developer Portal
  3. Update config

"Discord API returned status: 404"

Cause: Message or channel doesn't exist / bot can't see it Fix:

  1. Verify message ID is correct
  2. Verify channel ID is correct
  3. Ensure bot is in your Discord server
  4. Ensure bot has "Read Message History" permission

Rules show as fallback text

Cause: Discord fetch failing, using hardcoded fallback Fix:

  1. Check server logs for errors
  2. Verify bot token, channel ID, message ID
  3. Test bot permissions in Discord

👩‍💼 Holly's Editing Guide

Once everything is working, here's how Holly updates rules:

How to Edit Rules

  1. Go to Discord #server-rules channel
  2. Find the message with the rules for the server
  3. Right-click the message
  4. Click "Edit"
  5. Make your changes (use Discord markdown)
  6. Click "Save"

That's it! Next time someone types /rules in-game (or after 30 minutes when cache expires), they'll see the new version.

Discord Formatting Tips

Headers:

**This is a header**

Bullet points:

- First point
- Second point

Emojis that auto-convert:

  • 🔥 becomes [Fire] in orange
  • ❄️ becomes [Frost] in cyan
  • 💜 becomes [Arcane] in purple

Other emojis are removed (Minecraft can't display them)

Multi-Server Setup

If you have multiple servers (Fire Path, Frost Path, etc.):

  1. Create separate messages in #server-rules

    • Message 1: Fire Path Server Rules
    • Message 2: Frost Path Server Rules
    • Message 3: Creative Server Rules
  2. Each server's config points to its message:

    • Fire Path config → Message 1's ID
    • Frost Path config → Message 2's ID
    • Creative config → Message 3's ID
  3. Holly can edit each independently


📚 Appendix: Creating a Discord Bot

If you need a new bot (instead of using The Arbiter):

Step 1: Create Application

  1. Go to: https://discord.com/developers/applications
  2. Click New Application
  3. Name it: Firefrost Rules Bot
  4. Click Create

Step 2: Create Bot User

  1. Click Bot in the left sidebar
  2. Click Add BotYes, do it!
  3. Under Token, click Reset TokenYes, do it!
  4. Copy the token — save it somewhere safe
    • This is your bot token (only shown once!)

Step 3: Set Bot Permissions

  1. Still on Bot page
  2. Scroll to Privileged Gateway Intents
  3. DISABLE all three (you don't need them)
  4. Save Changes

Step 4: Invite Bot to Server

  1. Click OAuth2URL Generator in sidebar
  2. Under Scopes, check: bot
  3. Under Bot Permissions, check: Read Message History
  4. Copy the generated URL at the bottom
  5. Paste in browser → Select your Discord server → Authorize
  6. Bot joins your server!

Step 5: Use Token in Config

Copy the bot token into config/firefrostrules-server.toml:

bot_token = "YOUR_BOT_TOKEN_HERE"
