执行任务&#39；失败：编译Java&#39；。-本系列第三期

在此问题因已被提出而关闭之前，据我所知，这是一个模糊且常见的错误，因此此问题与其他问题不同。

我通过安装略微不同的Forge版本修复了以前post中的错误，但现在已达到this tutorial的第5步。当我将.gradlew构建与示例mod一起使用时，一切似乎都运行得很好(尽管我找不到控制台输出)，但当我将mod编辑为作者的描述时，我收到了许多错误。

示例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());
    }
}

我是如何按照教程进行更改的：

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生成时，我收到：

* What went wrong:
Execution failed for task ':compileJava'.
> Compilation failed; see the compiler error output for details.

我对Java了解不多(我刚刚开始学习)，但我认为逐个字符复制教程应该会产生一个没有错误的程序。显然不是。

查看编译器上的错误输出，第一个错误是‘导入网络无法解析’(第3行)，但我不知道原因。

任何帮助都非常感谢， 本

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

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