任务“：compileJava”的执行失败。 - 本系列第 3 期

Question

在这个问题因为已经被问到而关闭之前，据我所知这是一个模糊且常见的错误，因此这与其他问题不同。

我修复了之前 by installing a slightly different version of Forge, but have now reached Step 5 of this tutorial 中的错误。当我将 .\gradlew build 与示例 mod 一起使用时，一切似乎都运行良好（尽管我找不到控制台输出）但是当我将 mod 编辑为作者描述的方式时，我遇到了很多错误.

例子mod:

package com.example.examplemod;

import net.minecraft.init.Blocks;
import cpw.mods.fml.common.Mod;
import cpw.mods.fml.common.Mod.EventHandler;
import cpw.mods.fml.common.event.FMLInitializationEvent;

@Mod(modid = ExampleMod.MODID, version = ExampleMod.VERSION)
public class ExampleMod
{
    public static final String MODID = "examplemod";
    public static final String VERSION = "1.0";

    @EventHandler
    public void init(FMLInitializationEvent event)
    {
        // some example code
        System.out.println("DIRT BLOCK >> "+Blocks.dirt.getUnlocalizedName());
    }
}

我是如何改变它的，遵循教程：

package com.example.examplemod;

import net.minecraft.init.Blocks;
import cpw.mods.fml.common.Mod;
import cpw.mods.fml.common.Mod.EventHandler;
import cpw.mods.fml.common.event.FMLInitializationEvent;

@Mod(modid = ExampleMod.MODID, version = ExampleMod.VERSION)
public class ExampleMod
{
    public static final String MODID = "examplemod";
    public static final String VERSION = "1.1";

    @EventHandler
    public void init(FMLInitializationEvent event)
    {
        Block amethystOre = new ModBlock(Material.rock, "amethystOre");
        GameRegistry.registerBlock(amethystOre, "amethystOre");
    }

    private class ModBlock extends Block
    {
        public ModBlock(Material material, String blockName)
        {
            super(material);
            this.setBlockName(blockName);
            this.setBlockTextureName(MODID + ":" + blockName);
            this.setCreativeTab(CreativeTabs.tabBlock);
        }
    }

}

当我运行 .\gradlew 构建时，我得到：

我对 Java 了解不多（我才刚刚开始学习），但我认为逐个字符地复制教程应该会产生无错误的程序。显然不是。

查看编译器上的错误输出，第一个错误是 'The import net cannot be resolved'（第 3 行）我不知道为什么。

非常感谢任何帮助，本

导入错误。你应该使用 net.minecraft.* 而不是 net.minecraft.init.* :

import net.minecraft.block.Block;
import net.minecraft.block.material.Material;
