Android Studio发布项目到jcenter升级版

上篇文章是通过简单的配置方法进行上传到jcenter，看起来不具有普遍性，故作下文

第一步：

在项目的根 build.gradle中加入如下引入classpath

classpath 'com.android.tools.build:gradle:1.2.3'
classpath 'com.jfrog.bintray.gradle:gradle-bintray-plugin:1.0'
classpath 'com.github.dcendents:android-maven-plugin:1.2'

第二步：

在包的build.gradle中加入如下配置信息

apply plugin: 'com.android.library'
// 根节点添加
apply plugin: 'com.github.dcendents.android-maven'
apply plugin: 'com.jfrog.bintray'
// 根节点添加
version = "0.1"
android {
    compileSdkVersion 17
    buildToolsVersion "22.0.1"

    defaultConfig {
        minSdkVersion 8
        targetSdkVersion 17
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

def siteUrl = 'https://github.com/openproject/LessCode'                        // #CONFIG# // project homepage
def gitUrl = 'https://github.com/openproject/LessCode.git'                     // #CONFIG# // project git
group = "com.jayfeng"

install {
    repositories.mavenInstaller {
        // This generates POM.xml with proper parameters
        pom {
            project {
                packaging 'aar'
                name 'Less Code For Android'                                   // #CONFIG# // project title
                url siteUrl
                // Set your license
                licenses {
                    license {
                        name 'The Apache Software License, Version 2.0'
                        url 'http://www.apache.org/licenses/LICENSE-2.0.txt'
                    }
                }
                developers {
                    developer {
                        id 'ajiang'                                           // #CONFIG# // your user id (you can write your nickname)
                        name 'ajiang'                                       // #CONFIG# // your user name
                        email '********@qq.com'                               // #CONFIG# // your email
                    }
                }
                scm {
                    connection gitUrl
                    developerConnection gitUrl
                    url siteUrl
                }
            }
        }
    }
}

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

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

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

artifacts {
    archives javadocJar
    archives sourcesJar
}

Properties properties = new Properties()
properties.load(project.rootProject.file('local.properties').newDataInputStream())
bintray {
    user = properties.getProperty("bintray.user")
    key = properties.getProperty("bintray.apikey")
    configurations = ['archives']
    pkg {
        repo = "maven"
        name = "alipay"                                                 // #CONFIG# project name in jcenter
        websiteUrl = siteUrl
        vcsUrl = gitUrl
        licenses = ["Apache-2.0"]
        publish = true
    }
}

第三步：

在local.properties中加入如下

sdk.dir=D\:\\Android\\sdk
bintray.user=githubnewer
bintray.apikey=your key

最后：

进行命令行控制

gradlew javadocJar

gradlew sourcesJar

gradlewinstall

gradlew bintrayUpload

注1：如上方式很简单，但是在操作中会遇到不少问题，比如如下问题困扰我半天，最后终于解决了，特此记录一下

此原因是因为项目使用的gradle版本是2.4+，而插件版本是1.3-导致的

distributionUrl=https\://services.gradle.org/distributions/gradle-2.4-all.zip

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

解决：在gradle.wrapper中

distributionUrl=https\://services.gradle.org/distributions/gradle-2.2.1-all.zip

注2：在输入命令行的时候会遇到如下问题

* What went wrong:
Execution failed for task ':MaterialDesign:javadoc'.
> Javadoc generation failed. Generated Javadoc options file (useful for troubleshooting): 'D:\360\test\MaterialDesignLibrary-master\MaterialDesignLibrary\MaterialDesign\build\tmp\javadoc\javadoc.options'

向上翻查阅相关日志后发现，

D:\360\test\MaterialDesignLibrary-master\MaterialDesignLibrary\MaterialDesign\src\main\java\com\gc\materialdesign\widgets\SnackBar.java:153: 错误: 编码GBK的不可映射字符                                                             
                // TODO 鑷姩鐢熸垚鐨勬柟娉曞瓨鏍?    

应该是编码问题，导致build failed，所以只要将其转码即可

在包的build.gradle中加入

javadoc {
    options{
        encoding "UTF-8"
        charSet 'UTF-8'
    }
}
