gradle 自定义插件

gradle自定义规则有：
目录规则树 默认是src-> main
resources就只用这样
properties里面写类名：
格式： implementation-class=com.allen.rujews.plugins.allen

写插件语言 groovy （不是必须）
必须实现 apply接口
//allen.groovy

package com.allen.rujews.plugins

import org.gradle.api.Plugin
import org.gradle.api.Project

class allen implements Plugin<Project>{

    @Override
    void apply(Project target) {
        target.task(‘allen‘) << {
            println "fuck必须实现apply 也就是 apply plugin:时会调用"
        }
    }
}

//build.gradle

apply plugin: ‘maven‘
apply plugin: ‘groovy‘
dependencies {
//指定编译插件需要的依赖
implementation gradleApi()
implementation localGroovy()
}
//生成插件的task
uploadArchives {
repositories {
mavenDeployer {
        //我们发布到本地的地址，可以发布到jcenter上，具体可google下相关教程
        repository(url: uri(‘./allen‘))
        }
    }
}

运行命令：gradle uploadArchives

liuhailongdeMacBook-Air:allen liuhailong$ gradle uploadArchives

使用自定义的插件

//编译插件
/*
    apply plugin: ‘maven‘
    apply plugin: ‘groovy‘
    dependencies {
        //指定编译插件需要的依赖
        implementation gradleApi()
        implementation localGroovy()
    }
    //生成插件的task
    uploadArchives {
        repositories {
            mavenDeployer {
                    //我们发布到本地的地址，可以发布到jcenter上，具体可google下相关教程
                    repository(url: uri(‘./allen‘))
                    }
         }
    }
*/
//使用插件
buildscript {
    dependencies {
    classpath files(‘build/libs/allen.jar‘)
    }
}
apply plugin: ‘groovy‘
apply plugin: ‘com.allen.rujews.plugins.allen‘

dependencies {
    compile gradleApi()
    compile localGroovy()
}

命令：gradle allen

liuhailongdeMacBook-Air:allen liuhailong$ gradle allen

> Task :allen
fuck必须实现apply 也就是 apply plugin:时会调用
