Publish Mapping plugin for gradle

Why?

We created Publish Mapping because Gradle, by default, publishes all publications to all publishing repositories. This may not always be wanted.

How does it work?

This plugin works by disabling/removing the publish tasks that publish the publications to the wrong publish repository. It only understands tasks added by the ivy-publish and maven-publish plugins.

Adding to Gradle

buildscript {
	repositories {
		maven {
			url "http://dl.bintray.com/palantir/releases"
		}
		mavenCentral()
	}
	dependencies {
		classpath 'com.palantir:publish-mapping:2.0.0'
	}
}

apply plugin: 'ivy-publish' // or 'maven-publish'
apply plugin: 'publish-mapping'

Usage

The publish.mapping extension allows the project to specify which repositories (from publishing.repositories) each publication (from publishing.publications) should be published to. It does this by disabling the publish tasks that don't match the publish mapping. By default if a publication does not have an entry in the mapping, it will be published to all repositories by the publish task.

• put(String publicationName, List<String> repositoryNames) - Set a mapping entry
• add(String publicationName, List<String> repositoryNames) - Create a new or append to an existing mapping entry

publish.mapping {
  put 'PublicationName', ['RepositoryName1', 'RepositoryName2',...] // set a mapping entry
  add 'PublicationName', ['RepositoryName3', ...] // create a new mapping entry or append to an existing one
}

The following example shows how to specify that the publication ‘aaa’ should only be published to repositories ‘xxx’ and ‘yyy’, the publication ‘bbb’ should not be published to any repository, and the publication ‘ccc’ should be published to all repositories.

publishing {
  repositories {
    ivy {
      name 'xxx'
    }
    ivy {
      name 'yyy'
    }
    ivy {
      name 'zzz'
    }
  }
  publications {
    aaa(IvyPublication)
    bbb(IvyPublication)
    ccc(IvyPublication)
  }
}
publish.mapping {
  put 'aaa', ['xxx', 'yyy'] // 'aaa' is only published to repositories 'xxx' and 'yyy'
  put 'bbb', [] // 'bbb' is not published to any repository
  // by default 'ccc' is published to all repositories
}

Run the provided printPublishTasks task to see the expected behavior:

$ ./gradlew printPublishTasks
:printPublishTasks
Publish tasks run by 'publish':
-------------------------------
publishCccPublicationToZzzRepository
publishCccPublicationToYyyRepository
publishAaaPublicationToXxxRepository
publishAaaPublicationToYyyRepository
publishCccPublicationToXxxRepository

Publish tasks skipped by 'publish':
-----------------------------------
publishBbbPublicationToXxxRepository
publishBbbPublicationToYyyRepository
publishAaaPublicationToZzzRepository
publishBbbPublicationToZzzRepository

BUILD SUCCESSFUL
