mavenCentral() and jcenter() Gradle plugin

This Gradle plugin is used for mavenCentral() and jcenter() library publishing. It is created with a help from Jernej Virag and nuuneoi blogs.

This plugin is tested with Gradle/Gradle Wrapper = 2.14.1 and Gradle Build Tools 2.2.0

Code below is example of usage, you only need to change extra properties inside exc {...} in your library module build.gradle, set credentials inside gradle.properties or local.properties and add plugin classpath to root level build.gradle file:

Add the following to your root level build.gradle

classpath 'com.android.tools.build:gradle:2.2.0'

plugins {
    id "com.jfrog.bintray" version "1.7.1"
    id "com.github.dcendents.android-maven" version "1.4.1"
}

Add the following to your root level gradle.properties or local.properties

 # MAVEN
 signing.keyId=xxxxxxxx //gpg key
 signing.password=xxxxxxxx //gpg pass
 signing.secretKeyRingFile=/Users/<your_user>/.gnupg/secring.gpg
 ossrhUsername=xxxxxx //sonatype user
 ossrhPassword=xxxxxx //sonatype password
 stagingRepositoryUrl=https://oss.sonatype.org/service/local/staging/deploy/maven2/
 snapshotRepositoryUrl=https://oss.sonatype.org/content/repositories/snapshots/
 
 # JCENTRAL
 bintray.user=xxxxxx //bintray user
 bintray.apikey=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx //bintray api key
 bintray.gpg.password=xxxxxx //same as signing.password - gpg pass
 bintray.oss.user=xxxxxx //same as ossrhUsername - sonatype user
 bintray.oss.password=xxxxxx //same as ossrhPassword - sonatype user

Add the following to your library module folder build.gradle below your other Gradle configs

//... 
//rest of your library module gradle config code
//...

group = "com.github.kkontus.stringhelper"                // Maven Group ID for the artifact
archivesBaseName = "stringhelper"
//version = "1.0.7-SNAPSHOT"
version = "1.0.7"

ext {
    //project info
    projectName = "String Helper"
    packagingType = "aar"
    publishedGroupId = group
    publishedArtifactId = "some artifact id"
    projectDescription = "String Helper Library"
    siteUrl = 'https://github.com/kkontus/StringHelper'      // Homepage URL of the library
    libraryName = "stringhelper"
    repoName = "stringhelper"

    //scm info
    scmConnection = "scm:git:http://github.com/kkontus/StringHelper.git"
    scmDeveloperConnection = "scm:git:https://github.com/kkontus/StringHelper.git"

With this last line you have an option to use this plugin directly from Github by applying:

apply from: 'https://raw.githubusercontent.com/kkontus/mavencentral/master/central.gradle'

or you can download it as raw file and put it inside your library module folder and use it like

apply from: 'central.gradle'

To run Gradle script go to library module and run:

../gradlew uploadArchives for mavenCentral()

../gradlew bintrayUpload for jcenter()
