使用gradle上传项目到jcenter

想不想把自己的库也上传到jcenter，然后只需要一名话
compile com.zzb.library:android-common:0.1.0  //(compile group_id:artifact_id:version)

就可以引用你的库？
按着下面的教程一步一步来就可以了

1.到https://bintray.com/注册一个账号

2.AndroidStudio创建一个项目，然后再在这个项目里创建一个library(File->New->New Module->Android Library)

3.打开项目根目录的gradle.properties文件，复制下面的内容，替换相应字段的值

VERSION_NAME=0.1.0
GROUP=com.zzb.library
POM_NAME=jcenter test
POM_ARTIFACT_ID=common
POM_PACKAGING=aar
#比如我们引用appcompat-v7,那么会这么写 compile 'com.android.support:appcompat-v7:22.2.0'
#实际对应的字段就是 compile 'GROUP:POM_ARTIFACT_ID:VERSION_NAME'

POM_DESCRIPTION=项目描述
#项目地址等，我这使用的是github的项目地址
POM_URL=https://github.com/BaronZ/android-common-library
POM_SCM_URL=https://github.com/BaronZ/android-common-library
POM_SCM_CONNECTION=scm:git:git://github.com/BaronZ/android-common-library.git
POM_SCM_DEV_CONNECTION=scm:git:ssh://git@github.com/BaronZ/android-common-library.git

#开源协议

POM_LICENCE_DIST=repo

POM_DEVELOPER_ID=zzb
POM_DEVELOPER_NAME=ZZB

POM_DEVELOPER_EMAIL=realbo89@outlook.com
POM_DEVELOPER_URL=http://baronz.github.io

GIT_URL=https://github.com/BaronZ/android-common-library.git
ISSUE_URL=https://github.com/BaronZ/android-common-library/issues

4.项目目录下build.gradle，dependencies添加引用

dependencies {
        classpath 'com.android.tools.build:gradle:1.2.3'
        classpath 'com.jfrog.bintray.gradle:gradle-bintray-plugin:1.2'
    }
View Code

 注，如果不自己写gradle脚本，可跳过步骤5和6

5.项目目录下gradle目录添加文件gradle-jcenter-push.gradle，内容如下

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

publishing {
    publications {
        mavenJava(MavenPublication) {
            groupId GROUP
            version VERSION_NAME
            artifactId POM_ARTIFACT_ID
            artifact "${project.buildDir}/outputs/aar/${project.name}-release.aar"
            artifact androidJavadocsJar
            artifact androidSourcesJar

            pom.withXml {
                Node root = asNode()
                root.appendNode('name', POM_ARTIFACT_ID)
                root.appendNode('description', POM_DESCRIPTION)
                root.appendNode('url', POM_URL)

                def issues = root.appendNode('issueManagement')
                issues.appendNode('system', 'github')
                issues.appendNode('url', ISSUE_URL)

                def scm = root.appendNode('scm')
                scm.appendNode('url', POM_SCM_URL)
                scm.appendNode('connection', POM_SCM_CONNECTION)
                scm.appendNode('developerConnection', POM_SCM_DEV_CONNECTION)

                def license = root.appendNode('licenses').appendNode('license')
                license.appendNode('name', POM_LICENCE_NAME)
                license.appendNode('url', POM_LICENCE_URL)
                license.appendNode('distribution', POM_LICENCE_DIST)
            }
        }
    }
}

def getBintrayUserProperty() {
    return hasProperty('BINTRAY_USER') ? BINTRAY_USER : ""
}

def getBintrayApiKeyProperty() {
    return hasProperty('BINTRAY_APIKEY') ? BINTRAY_APIKEY : ""
}

// gradle bintrayUpload
bintray {
    user = getBintrayUserProperty()
    key = getBintrayApiKeyProperty()
    publications = ['mavenJava']

    dryRun = false
    publish = true
    pkg {
        repo = 'maven'
        name = POM_ARTIFACT_ID
        desc = POM_NAME
        websiteUrl = POM_URL
        issueTrackerUrl = ISSUE_URL
        vcsUrl = GIT_URL
        licenses = ['Apache-2.0']
        labels = ['android', 'aar']
        publicDownloadNumbers = true

        version {
            name = VERSION_NAME
            vcsTag = VERSION_NAME
        }
    }
}
View Code

 6.项目目录下gradle目录添加文件android-artifacts.gradle，内容如下

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

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

task androidSourcesJar(type: Jar) {
    classifier = 'sources'
    from android.sourceSets.main.java.sourceFiles
}
View Code

 7.在library目录下的build.gradle底部添加下面两行脚本

如果是执行了5和6，用下面脚本

apply from: rootProject.file('gradle/android-artifacts.gradle')
apply from: rootProject.file('gradle/gradle-jcenter-push.gradle')
View Code

如果没有5和6,用下面脚本

apply from: 'https://raw.githubusercontent.com/BaronZ/android-common/master/gradle/android-artifacts.gradle'
apply from: 'https://raw.githubusercontent.com/BaronZ/android-common/master/gradle/gradle-jcenter-push.gradle'
View Code

8.登录bintray.com创建maven库

  • 点击maven
  • 点击Add New Package
  • 填入相应的信息，再点Create Package即可
  • 回到bintray主页，点击edit
  • 点击API Key
  • 点击show，记下你的API Key，等下要用

9.找到你home目录下的gradle.properties(windows下目录是C:Users你的电脑名称.gradle)，添加下面两行脚本

BINTRAY_USER=你的bintray.com的用户名
BINTRAY_APIKEY=上面一步让你记下的API Key
View Code

10.好了，敲下面命令，坐等上传成功，cmd->进入你的项目目录（注，执行下面的命令，请确保设置好环境变量，path里面有gradle/bin,有JAVA_HOME环境变量）

gradle clean build bintrayUpload

 如果看到执行结果如下，那么恭喜你，还差一步

如果在生成Javadoc的时候遇到'编码GBK的不 可映射字符'错误，打开gradle/android-artifacts.gradle

添加下面代码到androidJavadocs这个任务里面

allprojects {
        tasks.withType(Javadoc) {
            options.encoding = "UTF-8"
        }
}
View Code

即完整脚本如下

task androidJavadocs(type: Javadoc) {
    source = android.sourceSets.main.java.srcDirs
    classpath += project.files(android.getBootClasspath().join(File.pathSeparator))
    allprojects {
        tasks.withType(Javadoc) {
            options.encoding = "UTF-8"
        }
    }
}
View Code

 11.还需要点add to jcenter，坐等审核通过

12.几个小时后，当你看到下面的截图，恭喜你，可以引用的你库了

13.下面一句话，引用你的库，大功告成

compile com.zzb.library:android-common:0.1.0

14.升级

确保global/gradle.properties里的BINTRAY_USER是正确的

修改library/gradle.properties的VERSION_NAME即可

 命令：gradle clean build bintrayUpload
