Gradle Maven Publication

Gradle scripts/plugin that helps to publish jar/aar artifacts with gradle maven or maven-publish plugin.

This repository contains two components: scripts and plugin.

The scripts work just like chrisbanes/gradle-mvn-push but suport with both maven and maven-publish, as well as more customization with pom.xml. The plugin is going to be a custom gradle plugin which makes the workflow much simpler.

Of course, the scripts/plugin are designed to work both with java and android project.

Getting Started

Script

Config the properties required by the script.
Apply the script file on demand in 'build.gradle'.
Run the script tasks to publish artifacts to local/remote repository.

Config the project properties (gradle.properties) like:

GROUP=com.kaedea
VERSION_NAME=0.1.0-SNAPSHOT

RELEASE_REPOSITORY_URL=
SNAPSHOT_REPOSITORY_URL=
NEXUS_USERNAME=
NEXUS_PASSWORD=

Apply the script in your project's build.gradle:

// We have 2 ways to apply the script:
// 1. apply from remote url
// 2. apply from scirpt file from 'project/gradle/..'

// For leagcy 'maven' plugin:
apply from: 'http://kaedea.github.com/gradle-maven-publication/gradle/maven.gradle'

// For dcendents's 'android-maven' plugin:
apply from: 'http://kaedea.github.com/gradle-maven-publication/gradle/maven-dcendents.gradle'

// For new 'maven-publish' plugin:
apply from: 'http://kaedea.github.com/gradle-maven-publication/gradle/maven-publish.gradle'

At last, run the following tasks to publish:

# For leagcy 'maven' or dcendents's 'android-maven' plugin:
gradle :uploadArchives

# For new 'maven-publish' plugin:
gradle :generatePomFileForArchivesPublication
gradle :publishToMavenLocal
gradle :publish

Upload to Bintray

Apply the bintray script to upload the artifacts to Bintray/JCenter (additional).

Config the project properties like:

BINTRAY_USERNAME=
BINTRAY_API_KEY=
BINTRAY_REPO=maven

Apply the script in your project's build.gradle as Script above, then apply the bintray script:

apply from: 'http://kaedea.github.com/gradle-maven-publication/gradle/bintray.gradle'

Run the following tasks to publish to Bintray:

gradle :bintrayUpload

Plugin

Publication plugin works in the same way of maven.gradle but much simpler.

Apply the 'com.kaedea.publication' plugin.
Config the properties.
Run tasks to publish artifacts to local/remote repository.

Apply plugin like:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.kaedea:publication:latest.integration'
    }
}
apply plugin: 'com.kaedea.publication'

Config the plugin:

publication {
    GROUP('com.kaedea')
    VERSION_NAME('0.1.0-SNAPSHOT')

    RELEASE_REPOSITORY_URL('')
    SNAPSHOT_REPOSITORY_URL('')
    NEXUS_USERNAME('')
    NEXUS_PASSWORD('')

    uploadToBintray = true
    BINTRAY_REPO('maven')
    BINTRAY_USERNAME('kaedea')
    BINTRAY_API_KEY('bintray_api_key')
}

Now, here you go with the publish tasks

gradle :uploadArchives
gradle :bintrayUpload
