Gradle Artifactory Plugin - How to publish artifacts from multiple modules in a project?

Question

I have a project which has a SharedCode (Java) module and secondly an Android (Android library) module which depends on the SharedCode

Answer 1

Going by artifactory multi-project examples on their github repo, it would seem that only the root project needs to have an artifactory{...} configuration section as opposed to in every sub-project as you have done.

Moreover when you declare publications('SharedCode') in the root project, artifactory plugin seems to be looking for a publication called sharedCode in every subproject.

I would try:

• Remove the artifactory{...} section from the android build.gradle

• Rename the android publication to sharedCode as well (or something more generic in both projects)

Update: As of version 4.6.0 of the com.jfrog.artifactory Gradle plugin, publishing artifacts in a multi-module project just does not work. From personal experience, you're best just abandoning this plugin and using the standard maven-publish plugin for Java library modules and the digital.wup.android-maven-publish plugin for Android library modules.

--- What follows below is my original answer before I posted the above update ---

So I've finally got this all working! Special thanks to @RaGe for helping me along the way. The key points to note are that the artifactory block needs to be in the project's root-level build.gradle file and not in the build.gradle file of the individual modules. Also, you need to add artifactoryPublish.skip=true to the project's root-level build.gradle file. See this GitHub repo for a full-on yet minimal-as-possible example:

https://github.com/adil-hussain-84/SO-35851251-Multiproject-Artifactory-Publish

In case the link ever stops working I'll paste the contents of the build.gradle files here also. Firstly, the project's root-level build.gradle file:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.5.0'
        classpath 'org.jfrog.buildinfo:build-info-extractor-gradle:4.0.1'
    }
}

allprojects {
    apply plugin: 'com.jfrog.artifactory'

    repositories {
        jcenter()
    }

    group = "${projectGroupName}"
    version = "${projectVersionName}"
}

artifactoryPublish.skip=true

artifactory {
    contextUrl = "${artifactory_url}"
    publish {
        repository {
            repoKey = 'libs-release-local'
            username = "${artifactory_username}"
            password = "${artifactory_password}"
        }
        defaults {
        publications('SomePublication')
            publishArtifacts = true
            properties = ['qa.level': 'basic', 'dev.team': 'core']
            publishPom = true
        }
    }
}

task wrapper(type: Wrapper) {
    gradleVersion = '2.8'
}

Secondly, the build.gradle file of the Android module:

apply plugin: 'com.android.library'
apply plugin: 'maven-publish'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

    defaultConfig {
        minSdkVersion 19
        targetSdkVersion 23
        versionCode Integer.parseInt("${projectVersionCode}")
        versionName "${projectVersionName}"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile project(':SharedCode')
    compile 'com.android.support:appcompat-v7:23.2.1'

    testCompile 'junit:junit:4.12'
}

publishing {
    publications {
        SomePublication(MavenPublication) {
            artifact "$buildDir/outputs/aar/Android-release.aar"

            //The publication doesn't know about our dependencies, so we have to manually add them to the pom
            pom.withXml {
                def dependenciesNode = asNode().appendNode('dependencies')

                //Iterate over the compile dependencies (we don't want the test ones), adding a <dependency> node for each
                configurations.compile.allDependencies.each {
                    def dependencyNode = dependenciesNode.appendNode('dependency')
                    dependencyNode.appendNode('groupId', it.group)
                    dependencyNode.appendNode('artifactId', it.name)
                    dependencyNode.appendNode('version', it.version)
                }
            }
        }
    }
}

Thirdly and finally, the build.gradle file of the SharedCode (Java) module:

apply plugin: 'java'
apply plugin: 'maven-publish'

dependencies {
    compile 'com.google.guava:guava:18.0'
}

publishing {
    publications {
        SomePublication(MavenPublication) {
            from components.java
        }
    }
}

That's it!

Version 4.2.0 of the Gradle Artifactory Plugin was released last week and added multiple Artifactory repositories deployment. Now you can simply define an artifactory closure with a different repository for different modules of the project.
