Custom entity breaks the whole mod

When I make a custom entity and export the mod it fails to export, does anybody know why?

Model file:

package net.mcreator.ccgame.client.model;

import net.minecraftforge.client.model.data.ModelData;

import net.minecraft.world.entity.Entity;
import net.minecraft.client.model.geom.ModelPart;
import net.minecraft.client.model.EntityModel;

import com.mojang.blaze3d.vertex.VertexConsumer;

// Made with Blockbench 3.7.4
// Exported for Minecraft version 1.17+ for Yarn
// Paste this class into your mod and generate all required imports
