首先看看有这几个文件：

屏幕快照 2017-10-24 20.19.57.png

上图的bintray.data.gradle，bintray.gradle和install.gradle其他项目也可以复用，只要修改bintray.data.gradle中相关的信息就可以了，非常简单。

• bintray.data.gradle（写你自己的配置）

ext {
    bintrayRepo = 'maven' //jcenter上的仓库名，习惯用maven
    bintrayName = 'imagepickermaster' //发布到JCenter上的项目名字
    bintrayUserOrg = 'supertxy' //jcenter 上的用户名
    publishedGroupId = 'com.github.SuperTxy' //groupId 
    libraryName = 'imagepickermaster' //name
    artifact = 'imagepickermaster' 

    libraryDescription = "image picker with video"

    siteUrl = 'https://github.com/SuperTxy/imagerpickermaster'
    gitUrl = 'https://github.com/SuperTxy/imagerpickermaster.git'

    libraryVersion = 'v1.6.5'

    developerId = 'SuperTxy'
    developerName = 'xxx'
    developerEmail = 'xxxx@gmail.com'

    licenseName = 'The Apache Software License, Version 2.0'
    licenseUrl = 'http://www.apache.org/licenses/LICENSE-2.0.txt'
    allLicenses = ["Apache-2.0"]
}

• bintray.gradle(配置bintray,一些task)

apply plugin: 'com.jfrog.bintray'
apply from: './bintray.data.gradle'

version = libraryVersion

if (project.hasProperty("android")) { // Android libraries
    task sourcesJar(type: Jar) {
        classifier = 'sources'
        from android.sourceSets.main.java.srcDirs
    }

    task javadoc(type: Javadoc) {
        options.addBooleanOption('Xdoclint:none', true)
        source = android.sourceSets.main.java.srcDirs
        classpath += project.files(android.getBootClasspath().join(File.pathSeparator))
        failOnError false
    }
} else { // Java libraries
    task sourcesJar(type: Jar, dependsOn: classes) {
        classifier = 'sources'
        from sourceSets.main.allSource
    }
}

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 = bintrayRepo
        name = bintrayName
        desc = libraryDescription
        websiteUrl = siteUrl
        vcsUrl = gitUrl
        licenses = allLicenses
        publish = true
        publicDownloadNumbers = true
    }
}

• install.gradle(关于install的)

apply plugin: 'com.github.dcendents.android-maven'
apply from: './bintray.data.gradle'

group = publishedGroupId

install {
    repositories.mavenInstaller {
        pom {
            project {
                packaging 'aar'
                groupId publishedGroupId
                artifactId artifact

                name libraryName
                description libraryDescription
                url siteUrl

                licenses {
                    license {
                        name licenseName
                        url licenseUrl
                    }
                }
                developers {
                    developer {
                        id developerId
                        name developerName
                        email developerEmail
                    }
                }
                scm {
                    connection gitUrl
                    developerConnection gitUrl
                    url siteUrl

                }
            }
        }
    }
}

接下来在下面的文件中加入相对的内容

• 在自己的library的build.gradle中加入：

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

• 在root build.gradle中加入

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.3'
        classpath'com.github.dcendents:android-maven-gradle-plugin:1.5'
        classpath 'com.jfrog.bintray.gradle:gradle-bintray-plugin:1.7.3'
    }
}

• 在local.properties中加入自己在jcenter上的用户名和apikey

bintray.user=YOUR_BINTRAY_USERNAME
bintray.apikey=YOUR_BINTRAY_API_KEY

接下来是上传了

在终端Terminal中输入 ./gradlew install 如果没有问题，再输入 ./gradlew bintrayUpload上传到jcenter就行了。

关于jcenter帐号的注册和maven 仓库的创建我就不再赘述了。
