How+to+convert+jar+to+mcaddon+verified (2024)

This guide covers everything: the , step-by-step translation methods , manual coding tweaks , and how to get your addon "verified" (signed and validated) to avoid the "Import Failed" error. Part 1: Understanding the Core Problem – Why JAR ≠ MCADDON Before touching any tools, understand this: You cannot "directly" convert a JAR to an MCADDON. They are fundamentally different:

"format_version": "1.20", "minecraft:recipe_shaped": "description": "identifier": "converted:ruby_block_recipe" , "tags": ["crafting_table"], "pattern": ["###", "###", "###"], "key": "#": "converted:ruby" , "result": "item": "converted:ruby_block", "count": 1

You must manually map each Java property to a Bedrock component. Java recipe (JSON): how+to+convert+jar+to+mcaddon+verified

"type": "crafting_shaped", "pattern": ["###", "###", "###"], "key": "#": "item": "minecraft:ruby" , "result": "item": "mod:ruby_block"

Bedrock’s block (in blocks/ruby_block.json ): This guide covers everything: the , step-by-step translation

"format_version": 2, "header": "name": "Converted Mod - Ruby Pack", "description": "From Java mod by OriginalAuthor", "uuid": "<generate unique UUID>", "version": [1, 0, 0], "min_engine_version": [1, 20, 70] , "modules": [ "type": "data", "uuid": "<generate second UUID>", "version": [1, 0, 0] ], "dependencies": [ "uuid": "<resource pack UUID from below>", "version": [1, 0, 0] ]

import world, ItemStack from "@minecraft/server"; world.afterEvents.itemUseOn.subscribe((event) => if (event.itemStack?.typeId === "converted:fire_sword") event.target.setFire(5); ); A verified MCADDON means Minecraft Bedrock recognizes it as safe, signed, and properly formatted. Unverified addons cause the dreaded "Import Failed. This pack is not valid" error. Step 5.1: Validate Internally Use Microsoft’s Validation Tool (part of the Minecraft Addon SDK): Step 5
