1.16.5的cot如何添加一个新的创造栏

ItemGroup.create("contenttweaker2", () => <item:minecraft:dragon_egg>);

#loader contenttweaker
import mods.contenttweaker.item.ItemBuilder;
import mods.contenttweaker.item.tool.ItemBuilderTool;
import crafttweaker.api.food.MCFood;

// 创建工具
new ItemBuilder()
    .withMaxDamage(100) // 耐久
    .withType<ItemBuilderTool>() // 将物品转换为工具，进行进一步关于工具的参数设定
    .withAttackDamage(10.0F) // 伤害值
    .withAttackSpeed(5.0F) // 攻击速度
    .withDurabilityCostAttack(1) // 用它打怪掉几点耐久，默认值为 2，一般普通工具为 2，剑为 1
    .withDurabilityCostMining(1) // 用它挖方块掉几点耐久，默认值为 0
    .withToolType(<tooltype:pickaxe>, 2, 3.0f) // 镐，挖掘等级为 2，挖掘速度为 3.0
    .build("bq1");


ItemGroup.create("contenttweaker2", () => <item:minecraft:dragon_egg>);

// 创建工具
new ItemBuilder()
    .withItemGroup(<itemGroup:contenttweaker2>)
    .withMaxDamage(100)
    .withType<ItemBuilderTool>()
    .withAttackDamage(10.0F)
    .withAttackSpeed(5.0F)
    .withDurabilityCostAttack(1) //By default: 2
    .build("bq1");


出现了下面的报错
