To convert the mod, you must extract the Java assets, convert them to Bedrock-compatible formats, and recreate the mod's logic using Bedrock JSON components or the GameTest Framework API. Step 1: Extract the JAR File
Converting a .jar file into a .mcaddon file isn’t as simple as renaming a file or running a quick one-click tool. It’s a complex, multi-step process that bridges two completely different Minecraft versions. However, with the right tools, some patience, and a clear understanding of what’s possible, you can bring your favorite Java Edition mods to Bedrock Edition. This guide will take you through everything you need to know to successfully convert your JAR file into a working MCADDON package.
Create a primary root folder named after your project (e.g., MyMod_Resource_Pack ). Inside this folder, create the following subdirectories:
While there isn't a simple "one-click" converter for every mod, you can use specialized tools and manual steps to bridge the gap. Below is a guide for a post on this topic.
This means the game reads the behavior pack logic but cannot find the texture or 3D geometry mapping. Check your textures/terrain_texture.json or textures/item_texture.json files for typographical errors. Convert Jar To Mcaddon
Move the textures from the extracted Java files into the appropriate directories within your Bedrock Resource Pack folder.
Select your current Java version and the Bedrock version you are targeting. Click to let the browser process the files. Download the newly generated Bedrock-ready .mcpack file. Step 3: Import into Minecraft Bedrock
While these tools focus primarily on world map conversion rather than mod conversion, they can help transfer custom block layouts and worlds utilizing modded elements from one platform to another. Conclusion
Before starting, it is crucial to understand what these files actually contain. To convert the mod, you must extract the
These are essentially renamed ZIP archives. They contain JSON files, JavaScript (via Bedrock Scripting API), textures, and audio files. Bedrock uses a structured data-driven system to load custom entities, blocks, items, and behaviors.
If your .jar file is a (adding new items, dimensions, or complex mechanics), you cannot simply convert it to .mcaddon . You
Converting a (Java Edition) mod into an .mcaddon (Bedrock Edition) file is a highly sought-after but complex task because the two versions of Minecraft use entirely different coding languages— Java vs. C++ .
Look at how the Java mod behaves and recreate it using Bedrock components: However, with the right tools, some patience, and
Bedrock controls entity behavior using components. You will recreate the Java logic inside an entity JSON file located in your Behavior Pack. For our exploding zombie example, you would use Bedrock's component system:
Converting a .jar to an .mcaddon is a rewarding project that bridges the gap between Minecraft's two massive communities. For servers, deploying is the fastest and most efficient way to achieve cross-play compatibility. For offline, standalone mods, utilizing Blockbench alongside manual behavior pack creation will allow you to successfully bring your favorite Java features over to Bedrock.
Select the tool that best fits your needs:
If the Java mod includes complex logic (e.g., custom magical systems, tech networks, advanced machinery), you must write scripts in JavaScript/TypeScript using the official Bedrock Beta APIs or GameTest Framework. Step 7: Package into an MCADDON
