In the Behavior Pack, create a blocks or entities folder. Write JSON files using Bedrock components (like "minecraft:creatable" , "minecraft:health" , or "minecraft:destructible" ) to mimic the behaviors defined in the Java mod's original code.
Ultimately, whether you need to convert a jar to an mcaddon for personal use or to share with the community, the process has shifted from an impossible task to a realistic, tool-supported workflow. While the final results still require patience and attention to detail, the landscape for bridging the two editions of Minecraft has never been more promising.

You don't need the code; you need the data . Use a decompiler like or IntelliJ IDEA . convert jar to mcaddon work
Minecraft is divided into two primary editions: and Bedrock Edition (which includes Windows 10/11, console, and mobile). While they share the same core, they are built on entirely different codebases. Java mods (files ending in .jar ) are designed for the Java ecosystem and generally do not work on Bedrock.
Create BP/blocks/ruby_ore.json :
Bedrock entity textures require exact mapping to match the new Bedrock geometry exported from Blockbench. Step 3: Map the Data (Recipes and Loot Tables) In the Behavior Pack, create a blocks or entities folder

The story begins with a player who finds a legendary Java mod—a
Because of these differences, your primary goal during conversion is to extract the assets (textures, models) and translation files, and then map the logic (behaviors, functions) into Bedrock’s component system. Step 1: Extract the Source Files from the .jar While the final results still require patience and
Both folders require a manifest.json file to tell Minecraft how they interact and to link them together. You can use an online Bedrock manifest generator to create these.

Go to File > Export and choose . This converts the Java model structure into the specific JSON format required by Bedrock Edition. Step 3: Set up the .mcaddon Structure
