If you have a favorite Java mod that you want to play on a phone, tablet, console, or Windows Bedrock edition, you cannot simply rename the file extension. Converting a JAR to an MCADDON requires translating Java code into JSON structures, behavior packs, and resource packs that Bedrock can interpret.
Go to File > Import > Java Block/Item or Bedrock Model depending on the file types found in the JAR's models/ folder.
JavaBE (by Stonebyte) is an emerging toolkit aimed at automating some of these manual workflows to bridge the gap between Java and Bedrock . 2. Texture and Model Porting (Visuals Only)
Inventory the JAR
and extract it. This gives you access to the original textures, models, and code. Convert Textures/Models : Use tools like the Texture Pack Version Converter to make Java assets compatible with Bedrock. Rewrite Behaviors : Java mods use files, while Bedrock Add-Ons use
Minecraft exists in two distinct ecosystems. Java Edition uses .jar files for mods, while Bedrock Edition utilizes .mcaddon or .mcpack files for its add-ons.
Recreate this in your Behavior Pack under blocks/block_name.json using Bedrock components like "minecraft:light_emission" or "minecraft:destructible_by_mining" . Porting Complex Mechanics (The Scripting API) Convert Jar To Mcaddon
Change the file extension from .jar to .zip . Use an archive utility (such as 7-Zip or WinRAR) to extract the contents into a dedicated working folder on your desktop.
If the .jar only contains new items, blocks, or entities (the visual parts), you can "port" them more easily.
JAR files containing only textures, sounds, and simple models can often be converted automatically using online tools or simple manual renaming. If you have a favorite Java mod that
Fix any broken textures or bounding box issues that occur due to format differences. Go to File > Export > Export Bedrock Geometry and save it. Step 3: Set Up Your Bedrock Add-on Structure
Select both your and Behavior Pack folders simultaneously.
