mc Fabricmod制作传送门

mc做个模组，我添加了依赖项，IntellijIDEA上面写着找不到依赖项:

package net.yzh.java.untitled3;

import net.fabricmc.api.ModInitializer;
import net.fabricmc.fabric.api.item.v1.FabricItemSettings;
import net.fabricmc.fabric.api.object.builder.v1.block.FabricBlockSettings;
import net.minecraft.block.Block;
import net.minecraft.block.Material;
import net.minecraft.item.BlockItem;
import net.minecraft.item.Items;
import net.minecraft.registry.Registries;
import net.minecraft.registry.Registry;
import net.minecraft.util.Identifier;

public class Untitled3 implements ModInitializer {
    public static final Block EXAMPLE_BLOCK = new Block(FabricBlockSettings.of(Material.METAL).strength(4.0f));
    @Override
    public void onInitialize() {
        Registry.register(Registries.BLOCK, new Identifier("yzh", "example_block"), EXAMPLE_BLOCK);
        Registry.register(Registries.ITEM, new Identifier("yzh", "example_block"), new BlockItem(EXAMPLE_BLOCK, new FabricItemSettings()));
        CustomPortalBuilder.beginPortal()
                .frameBlock(EXAMPLE_BLOCK)
                .lightWithItem(Items.ENDER_EYE)
                .destDimID(new Identifier("the_end"))
                .tintColor(45,65,101)
                .registerPortal();
    }
}

yzh是modid,截图如下:
