My mixin dosent work

[fringe shard]

Hi! I'm new to modding and don't know much about Java, and I wanted to ask what I'm doing wrong.
I wrote a simple mixin, specified the classes correctly, but when I try to run the game, it doesn't even attempt to start and gives me an error:
Mixin has no targets
@Mixin(DrawContext.class)
^

package com.danrus.appearanceOfDurability.mixin;

import net.minecraft.client.gui.DrawContext;
import net.minecraft.item.ItemStack;
import org.spongepowered.asm.mixin.Mixin;
import org.spongepowered.asm.mixin.injection.At;
import org.spongepowered.asm.mixin.injection.Inject;
import org.spongepowered.asm.mixin.injection.callback.CallbackInfo;

@Mixin(DrawContext.class)
public class DurabilityRender {
    @Inject(method = "drawItemInSlot", at = @At("HEAD"), cancellable = true)
    private void drawItemInSlot(int x, int y, ItemStack stack, CallbackInfo ci) {
        System.out.println("ItemStack: " + stack);
    }
}

....mixin.json

oh

i see the error

You are using a class that does not exist in that context

you need to go to your client package

and add the mixin there

@fringe shard

[fringe shard]

like this?

or src.client.java ?

[chrome veldt]

you need to go here

and create the mixin

mixin.client.DurabilityRender.java in there
