打包在本地的优势

• 不用搭建Maven库环境(当然想麻烦点搭建一个内网环境也是可以的)
• 无网络时可用(如果还没用镜像这个时间绝对很痛苦)
• 不需要审核(只是个人使用jcenter什么的太浪费时间)
• 随时修改源码(第三方库的bug不能及时修复，那就自己打包一个)
• 减少编译时间(不需要等待Library Module编译了)

快速使用

先来个栗子 libs-android
首先吧config.gradle复制到Project下(文件去栗子里下载)，接着修改Project和Module的build.gradle文件如下。

Project build.gradle 修改

buildscript {
    apply from : "config.gradle"
    ext.kotlin_version = '1.1.2-4'
    repositories {
        maven { url rootProject.ext.maven.aliyunMaven}
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.3'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        flatDir { dirs 'libs' }
        maven { url rootProject.ext.maven.sdkAndroidMaven }
        maven { url rootProject.ext.maven.sdkGoogleMaven }
        maven { url rootProject.ext.maven.sdkMaven }
        maven { url rootProject.ext.maven.localMaven}
        maven { url rootProject.ext.maven.localMavenSnapshots}
        maven { url rootProject.ext.maven.aliyunMaven}
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

Module build.gradle 添加

apply plugin: 'maven'

//https://github.com/wittyneko/libs-android
def siteUrl = 'https://github.com/wittyneko/libs-android'
//https://github.com/wittyneko/libs-android.git
def gitUrl = 'https://github.com/wittyneko/libs-android.git'
// 配置、配置、配置
group = "cn.wittyneko"
archivesBaseName = 'auto-layout'
version = '1.0.0-SNAPSHOT'

task sourcesJar(type: Jar) {
    from android.sourceSets.main.java.srcDirs
    classifier = 'sources'
}

task javadoc(type: Javadoc) {
    //title = ''
    //description = ''
    source = android.sourceSets.main.java.srcDirs
    classpath += project.files(configurations.provided.files,configurations.compile.files,android.getBootClasspath().join(File.pathSeparator))
    options {
        encoding 'utf-8'
        charSet 'utf-8'
        links 'http://docs.oracle.com/javase/7/docs/api/'
        linksOffline "https://developer.android.com/reference", "${android.sdkDirectory}/docs/reference"
    }
    exclude '**/BuildConfig.java'
    exclude '**/R.java'
    options.encoding = 'utf-8'
    failOnError false
}

task javadocJar(type: Jar, dependsOn: javadoc) {
    classifier = 'javadoc'
    from javadoc.destinationDir
}

artifacts {
    archives sourcesJar
    archives javadocJar
}

uploadArchives {
    repositories {
        mavenDeployer {
            String user = 'admin'
            String password = 'admin123'
            //先读取gradle.properties，不存在则读取local.properties
            Properties properties = rootProject.ext.android.properties
            user = rootProject.hasProperty('localUserName') ? rootProject.localUserName : (properties != null ? properties.getProperty('localUserName', user) : user)
            password = rootProject.hasProperty('localPassword') ? rootProject.localPassword : (properties != null ? properties.getProperty('localPassword', password) : password)
            println("user: $user, passowrd: $password")
            repository(url: rootProject.ext.maven.localMaven){
                authentication(userName: user, password: password)
            }
            snapshotRepository(url: rootProject.ext.maven.localMavenSnapshots){
                authentication(userName: user, password: password)
            }
        }
    }
}

执行./gradlew uploadArchives，等待打包完成查看$USER_HOME/.mymaven/snapshotRepository完成了
接下来详细说明，不想学点Gradle用法的飘过。

环境变量

不配置也是可以的还有gradlew嘛飘过。

GRADLE_HOME = 
GRADLE_USER_HOME = 
PATH = GRADLE_HOME/bin

Gradle属性配置文件

Gradle 的属性文件gradle.properties，在不同位置作用范围不一样
1). 全局配置
全局的Gradle属性文件默认在USER_HOME/.gradle/gradle.properties没有的话可一新建一个，这个配置在任何一个gradle文件都能读取到
2). Project配置
工程根目录下的gradle.properties文件，Project可读取，Module读取需要加上rootProject.
3). Module配置
同上

打包文档

1). 。。。

task javadoc(type: Javadoc) {
    //title = ''
    //description = ''
    source = android.sourceSets.main.java.srcDirs
    classpath += project.files(configurations.provided.files,configurations.compile.files,android.getBootClasspath().join(File.pathSeparator))
    options {
        encoding 'utf-8'
        charSet 'utf-8'
        links 'http://docs.oracle.com/javase/7/docs/api/'
        linksOffline "https://developer.android.com/reference", "${android.sdkDirectory}/docs/reference"
    }
    exclude '**/BuildConfig.java'
    exclude '**/R.java'
    options.encoding = 'utf-8'
    failOnError false
}

task javadocJar(type: Jar, dependsOn: javadoc) {
    classifier = 'javadoc'
    from javadoc.destinationDir
}

artifacts {
    archives javadocJar
}

2). 。。。

android.libraryVariants.all { variant ->
    println variant.javaCompile.classpath.files
    if(variant.name == 'release') { //我们只需 release 的 javadoc
        task("generate${variant.name.capitalize()}Javadoc", type: Javadoc) {
            // title = ''
            // description = ''
            source = variant.javaCompile.source
            classpath = files(variant.javaCompile.classpath.files, project.android.getBootClasspath())
            options {
                encoding "utf-8"
                links "http://docs.oracle.com/javase/7/docs/api/"
                linksOffline "http://d.android.com/reference", "${android.sdkDirectory}/docs/reference"
            }
            exclude '**/BuildConfig.java'
            exclude '**/R.java'

            failOnError false
        }
        task("javadoc${variant.name.capitalize()}Jar", type: Jar, dependsOn: "generate${variant.name.capitalize()}Javadoc") {
            classifier = 'javadoc'
            from tasks.getByName("generate${variant.name.capitalize()}Javadoc").destinationDir
        }
        artifacts {
            archives tasks.getByName("javadoc${variant.name.capitalize()}Jar")
        }
    }
}

打包源码

task sourcesJar(type: Jar) {
    from android.sourceSets.main.java.srcDirs
    classifier = 'sources'
}

artifacts {
    archives sourcesJar
}

上传到本地Maven库

apply plugin: 'maven'

group = "cn.wittyneko"
archivesBaseName = 'auto-layout'
version = '1.0.0-SNAPSHOT'

uploadArchives {
    repositories {
        mavenDeployer {
            String user = 'admin'
            String password = 'adminpsd'
            //先读取gradle.properties，不存在则读取local.properties
            Properties properties = rootProject.ext.android.properties
            user = rootProject.hasProperty('localUserName') ? rootProject.localUserName : (properties != null ? properties.getProperty('localUserName', user) : user)
            password = rootProject.hasProperty('localPassword') ? rootProject.localPassword : (properties != null ? properties.getProperty('localPassword', password) : password)
            println("user: $user, passowrd: $password")
            repository(url: rootProject.ext.maven.localMaven){
                authentication(userName: user, password: password)
            }
            snapshotRepository(url: rootProject.ext.maven.localMavenSnapshots){
                authentication(userName: user, password: password)
            }
        }
    }
}
