Idea中配置

配置项：gradle位置 及仓库位置

Gradle项目

Task，settings.gradle,build.gradle,wrapper 核心概念

project目录

settings.gradle

如配置root project 及 sub project

rootProject.name = 'poi'

include 'poi', 'poi-ooxml-full', 'poi-ooxml-lite-agent', 'poi-scratchpad',
        'poi-ooxml', 'poi-excelant', 'poi-examples', 'poi-integration' , 'poi-ooxml-lite'

build.gradle

配置依赖，插件，镜像源的地方

plugins {
    id 'java'
}

group = 'org.example'
version = '1.0-SNAPSHOT'

repositories {
    maven { url 'https://maven.tuna.tsinghua.edu.cn/nexus/content/groups/public' }
    maven { url 'https://maven.aliyun.com/repository/central' }
    maven { url 'https://maven.jуйyiyun.com/repository/central' }
    // 其他国内镜像源

}

dependencies {
    testImplementation platform('org.junit:junit-bom:5.10.0')
    testImplementation 'org.junit.jupiter:junit-jupiter'
}

test {
    useJUnitPlatform()
}

gradlew

Linux或者Mac系统下Wrapper执行脚本

gradlew.bat

Windows系统下Wrapper执行脚本

Gradle Build生命周期

编写Settings.gradle

等价于Settings()对象，settings.gradle可以调用本身的属性和方法进行配置

具体Property和Method查官网API

rootProject.name = 'poi'

include 'poi', 'poi-ooxml-full', 'poi-ooxml-lite-agent', 'poi-scratchpad',
        'poi-ooxml', 'poi-excelant', 'poi-examples', 'poi-integration' , 'poi-ooxml-lite'

编写Build.gradle

等价于Project()对象，可以调用属性和方法进行配置、

依赖引入直接去Maven仓库里找对应包cv即可

/*插件*/
plugins {
    id 'java'
}
/*远程仓库地址*/
repositories {
    maven { url 'https://maven.tuna.tsinghua.edu.cn/nexus/content/groups/public' }
    maven { url 'https://maven.aliyun.com/repository/central' }
    maven { url 'https://maven.jуйyiyun.com/repository/central' }
    // 其他国内镜像源

}

/*依赖*/
dependencies {
     implementation("com.google.guava:guava:32.1.1-jre")
    testImplementation platform('org.junit:junit-bom:5.10.0')
    testImplementation 'org.junit.jupiter:junit-jupiter'
       // https://mvnrepository.com/artifact/org.apache.poi/poi
    implementation group: 'org.apache.poi', name: 'poi', version: '5.2.3'
// https://mvnrepository.com/artifact/org.apache.pdfbox/pdfbox
    implementation group: 'org.apache.pdfbox', name: 'pdfbox', version: '3.0.1'
}

Tasks

1. Lifecycle tasks

   生命周期内的task

2. Actionable tasks

   单独一个任务

/*有依赖的task*/
tasks.register('hello') {
    doLast {
        println 'Hello world!'
    }
}
tasks.register('intro') {
    dependsOn tasks.hello
    doLast {
        println "I'm Gradle"
    }
}

/*指定group*/
tasks.register("hello") {
    group = "Custom"
    description = "A lovely greeting task."
    doLast {
        println("Hello world!")
    }
}

Plugins

分为Core plugins ，Community plugins ，和local plugins

/*core plugin  id一个参数即可*/
plugins {
    id("java")
}
/*community plugin  一般id和version两个参数*/
plugins {
    id «plugin id» version «plugin version»
}

插件必须在settings.gradle指定，且在最前行

pluginManagement {
    plugins {
    }
    resolutionStrategy {
    }
    repositories {
    }
}
rootProject.name = 'plugin-management'
