gradle笔记

allprojects和subprojects区别

allprojects是对所有project的配置，包括Root Project。而subprojects是对所有Child Project的配置

settings.gradle

配置子模块

build.gradle例子

buildscript { // 指定脚本自身使用的资源
    repositories {
        mavenLocal()
        maven { url 'http://maven.aliyun.com/nexus/content/groups/public/' }
        mavenCentral()
    }
}
group 'cqt.goai'
version '1.0-SNAPSHOT'

allprojects {
    apply plugin: 'java'
    apply plugin: 'idea'
    sourceCompatibility = 1.8 // jdk版本
    dependencies { // 注意testCompile 和 compile 区别，compile才能给子模块搜索到
        testCompile group: 'junit', name: 'junit', version: '4.12'
        compile group: 'io.netty', name: 'netty-all', version: '4.1.33.Final'
        compile group: 'org.quartz-scheduler', name: 'quartz', version: '2.3.0'
        compile fileTree(dir: 'libs', include: ['*.jar'])
    }

// 复制jar包到指定文件
task copyJar(type:Copy) {
        from ('build\\libs')
        into ('.')
    }

 // 指定程序入口
    jar {
        from { configurations.runtime.collect{zipTree(it)} } // 打包依赖
        manifest {
            attributes("Main-Class": "com.zyf.common.netty.websocket.server.NettyServerLauncher")
        }
    }
}

gradle仓库

buildscript {
    repositories {
        maven { url 'http://maven.aliyun.com/nexus/content/groups/public/' }
        mavenCentral()
    }
}

gradle中文教程

https://www.w3cschool.cn/gradle_user_guide/gradle_user_guide-v6kt26h2.html

编译并打包你的代码, 但是并不运行单元测试

 gradle build -x test 
pause

多模块，一个模块引用另一个模块

dependencies {
    compile project(':shared')
}

解决 IDEA 创建 Gradle 项目没有src目录

task "create-dirs" << {
    sourceSets*.java.srcDirs*.each {
        it.mkdirs()
    }
    sourceSets*.resources.srcDirs*.each{
        it.midirs()
    }
}

gradle打包脚本

gradle clean build -x test 

gradle 指定打包的resources文件

processResources {
   include "**/logback.xml"
   include "**/config**.yml"
}

打包指定入口类和打包依赖

jar {
    from { configurations.runtime.collect{zipTree(it)} } // 打包依赖
    manifest {
        attributes("Main-Class": "ServerApplication")
    }
}

复制jar包

task copyJar(type:Copy){
    from ('build\\libs')
    into ('.')
}

依赖本地jar文件夹：

compile fileTree(dir:'libs',include:['*.jar'])

多模块gradle配置

• build.gradle

group 'com'
version '1.0-SNAPSHOT'

allprojects {
    repositories {
        mavenLocal()
        mavenCentral()
    }

    // 多模块最重要这三个，加到allprojects里
    apply plugin: 'java'
    apply plugin: 'idea'
    sourceCompatibility = 1.8


    dependencies {
        testCompile group: 'junit', name: 'junit', version: '4.12'
    }
}

• setting.gradle

rootProject.name = 'irssystem'
include 'irs'
include 'common'
include 'apigateway'

• 子模块引用其他子模块

dependencies {
    compile project(":common")
}
