I want to craft a tool which has a enchant it self. e.g a pickaxe has EFFICIENCY

Forge added an NBT tag (called "nbt" obviously) to outputs as they return an ItemStack and not a simple ingredient. The format is the same as any other nbt tag out in the wilderness of the Minecraft files.

You're creating a recipe. You're making it in a json file. You need it on the output. The json object is called "nbt".

您正在创建食谱。您正在json文件中创建它。您需要在输出中使用它。json对象称为“ nbt”。

Correct, that is not valid JSON.

Please install a JSON plugin in your IDE if it doesn't have one already.

But how can i correct it

"nbt":{
        "ench":{"id":32,"lvl":2}
        }

I write down this but the item still has enchant when i craft it

Let's see, first the version you are referencing with an id number is no longer supported. Second, you should look over ItemStack::addEnchantment to see how enchantment tags are written to.

 

In case you don't understand, I'll do a bit of translation. Almost everything inside your nbt tag is wrong. First, the ListNBT (JsonArray) name is called "Enchantments" and not "ench". Second, the ListNBT hold an list of CompoundNBTs (JsonObjects). Each CompoundNBT holds two parameters: a String "id" holding the registry name of the enchantment and a short "lvl" holding the enchantment level. The value for "lvl" is clamped between 0-255 anyways so you should not exceed those bounds.

 

Follow the link that diesieben07 sent and if you really need more of an example, enchant an item in game and open the player data file through an NBT reader so you can see how its structured.
