创建项目

使用IDEA创建一个Minecraft项目：

解决gradle构建慢的问题

链接

在gradle.properties中：

systemProp.http.proxyHost=127.0.0.1
systemProp.http.proxyPort=7890
systemProp.http.nonProxyHosts=10.*|localhost

systemProp.https.proxyHost=127.0.0.1
systemProp.https.proxyPort=7890
systemProp.https.nonProxyHosts=10.*|localhost

切换fabric以及mavencenter源，settings.gradle

pluginManagement {
    repositories {
        maven {
            name = 'Fabric'
            url = 'https://repository.hanbings.io/proxy'
        }
        gradlePluginPortal()
    }
}

build.gradle

repositories {
    maven {
        url 'https://maven.aliyun.com/nexus/content/groups/public'
    }
    maven {
        url 'https://repository.hanbings.io/proxy'
    }
}

开始编写代码

我们的DemoMod1需要实现ModInitializer接口

DemoMod1Client需要实现ClientModInitializer接口

public class DemoMod1 implements ModInitializer {
    @Override
    public void onInitialize() {

    }
}

public class DemoMod1Client implements ClientModInitializer {
    @Override
    public void onInitializeClient() {

    }
}

同时在resources目录下的fabric.mod.json文件中，需要设置这两个类的位置：

"entrypoints": {
  "client": [
    "com.cxk.demo_mod1.client.DemoMod1Client"
  ],
  "main": [
    "com.cxk.demo_mod1.DemoMod1"
  ]
},

简单些一点代码：

public class DemoMod1 implements ModInitializer {
    public static final String MOD_ID = "demo_mod1";
    public static final Logger LOGGER = Logger.getLogger(MOD_ID);

    @Override
    public void onInitialize() {
        LOGGER.info("Hello Fabric world!");

    }
}

运行代码

可以看到控制台打印信息了，游戏也正常启动，说明mod生效了

有时候可能会因为版本冲突原因启动不了，这里给一个不冲突的版本：
