How To Convert Jar To Mcaddon Patched · Hot & Extended
A .jar file is essentially a .zip file.
⚠️ The "Patched" catch: Geyser translates vanilla Java features perfectly. But for mods, it only works if the mod uses standard Java packets. Many mods break. There is a community fork called GeyserPlus that patches additional mod compatibility (e.g., for Origins mod).
Converting a .jar to a patched .mcaddon involves extracting assets, reformatting models in Blockbench, writing custom manifest files, and—if you're lucky—using a proxy server like Geyser to simulate the mod's behavior. The process is technical, time-consuming, and rarely perfect. But for those who enjoy the challenge, building your own patched addon teaches you more about Minecraft's internals than a thousand tutorials.
Start with a simple texture pack mod (like a Java shader converted to Bedrock). Once you master the asset pipeline, attempt a simple item mod. Only then should you touch entity or logic conversion. Good luck, and happy patching.
Converting a Java .jar file to a Bedrock .mcaddon is a complex task because Java and Bedrock use different programming languages (Java vs. C++) and rendering engines. In this context, "patched" typically refers to using a modified version of Minecraft Bedrock (like Minecraft Patched PE) that restores features like custom shader support or third-party script compatibility. How to Convert JAR to MCAddon (Step-by-Step)
Since there is no "one-click" tool to fully convert code-heavy Java mods to Bedrock, the process is split between simple asset conversion and manual code rebuilding. 1. Convert Assets (Textures & Models)
If your .jar file contains textures or 3D models, you can port these parts relatively easily.
There is no automated way to convert a Java .jar mod into a Bedrock .mcaddon file. Because Java Edition and Bedrock Edition are built on completely different programming languages (Java vs. C++) and use entirely different rendering and behavior systems, a .jar cannot simply be "patched" or repackaged into an addon.
To bring a Java mod over to Bedrock, you must manually recreate the assets and rewrite the game logic. This guide outlines the proper process for manually converting and structuring your project into a working .mcaddon. 🛠️ Step 1: Extract the Java Assets
To get started, you will extract the original textures, models, and sounds from the Java .jar file to use as a baseline for your Bedrock addon.
Locate the .jar file: Find the Java mod file you wish to port.
Unpack the archive: Change the file extension from .jar to .zip or use an extraction tool like 7-Zip.
Grab the assets: Open the extracted folder and navigate to assets/modid/ (where "modid" is the name of the mod). Copy the textures, models, and sounds folders to a new workspace on your computer. 🎨 Step 2: Convert the Assets for Bedrock how to convert jar to mcaddon patched
Bedrock Edition handles textures and entity models differently than Java. You must adapt these files so the game can read them properly. For Resource Packs (Textures & Models)
Textures: Java uses individual .png files that usually map directly, but you may need to reorganize the folders to match the Bedrock directory (textures/blocks, textures/items).
Entity Models: Java entity models (often written in .java or .json for Geckolib) are formatted differently than Bedrock's geometry files. Use a 3D modeling tool like Blockbench to import your Java models and export them specifically as Bedrock Geometry (.geo.json). 💻 Step 3: Recreate Mod Behaviors (Scripting & JSON)
This is where the actual "conversion" happens. You cannot use the Java code. You must look at what the Java mod does and code it from scratch for Bedrock.
Component System: Bedrock uses a component-based JSON system for entity behaviors. Map out the behaviors from the Java mod (e.g., custom health, movement speed, or attack damage) and write them into Bedrock behavior files inside a behavior_packs folder.
Bedrock Scripting API: For complex logic that JSON cannot handle (like custom UI or advanced magic systems), you will need to use Bedrock's JavaScript-based Scripting API. Read the Java mod's source code to understand its math or logic, and rewrite those functions in JavaScript. 📦 Step 4: Package into an .mcaddon
Once you have created both your Resource Pack (visuals) and your Behavior Pack (logic), you need to combine them into a single installable file. ZIP To MCADDON Tutorial for minecraft mods made easy!!
Converting a .jar file (typically a Minecraft Java Edition mod) into a .mcaddon ( Bedrock Edition
) is a complex process because Java mods use compiled code that Bedrock cannot read. While there is no "one-click" universal converter, new tools like JavaBE from Stonebyte aim to bridge this gap by automating the conversion of assets and basic structures into Bedrock-ready files. Methods for Conversion
Automated Tools (JavaBE):The Stonebyte toolkit (formerly CodeNex) includes a tool called JavaBE. It automates the generation of Bedrock packs, sets up folder structures, and optimizes assets from .jar mods into .mcaddon format.
Visual Asset Porting (Blockbench):If the mod contains custom 3D models or items, you can use Blockbench to import Java models and export them as Bedrock geometry. Import the Java model via File > Add Java block/item model. Adjust pivot points to zero for Bedrock compatibility. Export the file as Bedrock geometry for use in your addon.
Resource Pack Conversion (Thunder):If the .jar is primarily a texture pack, use Thunder by GeyserMC. This GUI tool allows you to select a Java pack and convert it directly into a Bedrock .mcpack. ⚠️ The "Patched" catch: Geyser translates vanilla Java
Manual Code Redesign:Because Java mods use APIs (like Forge or Fabric) that Bedrock does not support, complex logic must often be rewritten manually using Bedrock’s JSON-based components or the Scripting API. Structure of a Converted .mcaddon
A functional .mcaddon patched from a Java source typically requires two main components:
Behavior Pack: Contains the logic (JSON files) for how entities and blocks act. Resource Pack: Contains the textures, models, and sounds.
Manifest.json: Each pack needs a manifest.json file with unique UUIDs to be recognized by Minecraft. Limitations to Consider
Logic Gaps: Complex Java code (like custom AI or world-gen logic) cannot be automatically "patched" and usually requires a complete redesign in Bedrock.
Feature Parity: Some Java features, like specific Optifine shaders or complex GUI modifications, may not work even after conversion.
Converting a Java .jar mod directly into a Bedrock .mcaddon is inherently complex because the two versions use completely different coding languages (Java vs C++). However, you can achieve this by using automated tools like JavaBE or by manually porting the assets. Option 1: Automated Conversion with JavaBE
JavaBE is a specialized toolkit designed to bridge the gap between Java mods and Bedrock addons by automating the file restructuring process.
Obtain JavaBE: Visit the Stonebyte developer page to access the tool.
Upload the .jar: Select your compiled Java mod JAR file within the JavaBE interface.
Process and Map: The tool automatically maps Java entities and structures to their Bedrock equivalents, generating necessary Behavior Packs and Resource Packs.
Download .mcaddon: Once optimization is complete, download the final .mcaddon file. Converting a
Import to Minecraft: Double-click the .mcaddon file to automatically import it into Minecraft Bedrock Edition. Option 2: Manual Porting (Asset-Based)
If you only need the visual elements (textures and models) of a mod, you can port them manually using tools like Blockbench. How to Open a Java JAR File in Windows

Title: How to Convert a Java .jar Mod to a Patched .mcaddon (Bedrock Edition)
Important Disclaimer:
You cannot directly convert a Java .jar mod into a fully functional Bedrock .mcaddon in most cases. Java mods use completely different code (Java vs. C++/JavaScript), APIs (Forge/Fabric vs. Bedrock's addon system), and rendering engines. However, for simple content like items, blocks, entities, or basic behaviors—if you have the source assets and logic—you can manually recreate the addon and package it as a .mcaddon.
This guide shows the manual porting process, not an automated tool. If you're looking for a converter tool, none exists that works for complex mods.
The Minecraft modding community is vast, but a painful divide exists between Java Edition and Bedrock Edition. You find an amazing mod, shader, or UI pack online, only to realize it ends in .jar—useless for console, mobile, or Windows 10 players.
Converting a .jar (Java Edition archive) to an .mcaddon (Bedrock Edition add-on) isn't just a simple file rename. It requires decoding, translating, and patching the files to work within Bedrock’s different architecture.
This guide covers the tools, the process, and how to ensure your converted file is properly "patched" for stability.
Before diving in, it is vital to understand what you are up against:
The Reality Check: You cannot convert complex Java mods (like "Create" or "JEI") directly to Bedrock. Those require rewriting code from scratch. However, you can convert:
This method doesn't create a true .mcaddon, but it allows Bedrock players to use Java mods on a Java server.
If you want to bring a Java mod to Bedrock, here’s the step-by-step process advanced creators use.
