Android Studio發布到Jcenter

編輯：關於Android編程

1.前言

擁抱開源，熱愛開源，將我們認為不錯的代碼開源到gihtub，將我們的庫發布到jcenter\mevan等。

2.准備工作

2.1 准備

申請倉庫賬號注意model為android library項目

2.2 插件引入

在根目錄的gradle文件下加入

classpath 'com.jfrog.bintray.gradle:gradle-bintray-plugin:1.2'
        classpath 'com.github.dcendents:android-maven-plugin:1.2'

個人認為這１個最好保持一直。
最後我們根目錄下的gradle文件變成這個樣子

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.3.0'
        classpath 'com.jfrog.bintray.gradle:gradle-bintray-plugin:1.2'
        classpath 'com.github.dcendents:android-maven-plugin:1.2'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

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

2.3 在根目錄下創建一個bintray.gradle文件(必須這名字)

group = PROJ_GROUP
version = PROJ_VERSION
project.archivesBaseName = PROJ_ARTIFACTID

apply plugin: 'com.jfrog.bintray'
apply plugin: 'maven-publish'

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

task javadoc(type: Javadoc) {
    source = android.sourceSets.main.java.srcDirs
    classpath += configurations.compile
    classpath += project.files(android.getBootClasspath().join(File.pathSeparator))
}

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

javadoc {
    options{
        encoding "UTF-8"
        charSet 'UTF-8'
        author true
        version true
        links "http://docs.oracle.com/javase/7/docs/api"
        title PROJ_ARTIFACTID
    }
}

artifacts {
    archives javadocJar
    archives sourcesJar
}

def pomConfig = {
    licenses {
        license {
            name "The Apache Software License, Version 2.0"
            url "http://www.apache.org/licenses/LICENSE-2.0.txt"
            distribution "repo"
        }
    }
    developers {
        developer {
            id DEVELOPER_ID
            name DEVELOPER_NAME
            email DEVELOPER_EMAIL
        }
    }
    //這裡有引號，並且有個空格，否則生成不了依賴，主要是這裡的dependencies並不是build.gradle裡的dependencies，而gradle會把他當成自身的dependencies處理
    "dependencies " {
//        dependency{
//            groupId "com.alibaba"
//            artifactId "fastjson"
//            "version " "1.2.6"
//            //同dependencies
//        }
    }

}

publishing {
    publications {
        mavenJava(MavenPublication) {
            artifactId PROJ_ARTIFACTID

            pom{
                packaging 'aar'
            }
            pom.withXml {
                def root = asNode()
                root.appendNode('description', PROJ_DESCRIPTION)
                root.children().last() + pomConfig
            }
        }
    }
}

bintray {
    Properties properties = new Properties()
    properties.load(project.rootProject.file('local.properties').newDataInputStream())

    user = properties.getProperty('BINTRAY_USER');
    key = properties.getProperty('BINTRAY_KEY');



    configurations = ['archives']
    publications = ['mavenJava']
    publish = true

    pkg {
        repo = 'maven'
        name = PROJ_NAME
        desc = PROJ_DESCRIPTION
        websiteUrl = PROJ_WEBSITEURL
        issueTrackerUrl = PROJ_ISSUETRACKERURL
        vcsUrl = PROJ_VCSURL
        licenses = ['Apache-2.0']
        publicDownloadNumbers = true
    }
}

上述文件幾乎不用修改，假如你將要上傳的包　包含其他的三方庫。在以下塊中進行申明

"dependencies " {
//        dependency{
//            groupId "com.alibaba"
//            artifactId "fastjson"
//            "version " "1.2.6"
//            //同dependencies
//        }
    }

通俗易懂，一目了然，就不多做解釋了。

2.4 剩余配置

在Model對應的gralde文件中配置簽名\引入bintray.gradle,最終代碼如下，如看不懂配置相關，閱讀這篇　或者自行閱讀gradle for android


apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

    signingConfigs {
        config {
            keyAlias 'guolei'
            keyPassword '123456'
            storeFile file('guolei.jks')
            storePassword '123456'
        }
    }
    defaultConfig {
        applicationId "com.gl.draggridview"
        minSdkVersion 17
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            signingConfig signingConfigs.config
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    //compile 'com.android.support:appcompat-v7:23.1.1'

}
apply from:'../bintray.gradle'

注意bintray.gradle 一定要放在文件最下面。

配置BINTRAY_KEY 和BINTRAY_USER　也就是一開始注冊的那個
這裡寫圖片描述

guolei1130 為我的用戶名，查看key 點擊ｅｄｉｔ，
這裡寫圖片描述

點api key ,show 即可看到。
在根目錄下的local.properties 配置。

BINTRAY_KEY=e21c3f96df17xxxxxxxx
BINTRAY_USER=guolei1130

這裡對應的是bintray.gradle中的這一段代碼，當然，你可以修改這段代碼，將這２個屬性寫在任意位置

Properties properties = new Properties()
    properties.load(project.rootProject.file('local.properties').newDataInputStream())

    user = properties.getProperty('BINTRAY_USER');
    key = properties.getProperty('BINTRAY_KEY');

最後，sync now。
