Gradle plugin that creates a publish task to automatically upload all of your Java, Kotlin or Android libraries to any Maven instance. This plugin is based on Chris Banes initial implementation and has been enhanced to add Kotlin support and keep up with the latest changes.


For modifying what is getting published see configuring what to publish.

There is also a base plugin that doesn't apply any default configuration and allows the most customization.

Supported plugins

The output of the following Gradle plugins is supported to be published with this plugin:

  • org.jetbrains.kotlin.jvm
  • org.jetbrains.kotlin.multiplatform
  • java
  • java-library
  • java-gradle-plugin
  • com.gradle.plugin-publish
  • java-platform
  • version-catalog

Advantages over maven-publish

Gradle ships with the maven-publish and many other plugins like the Android Gradle Plugin or the Kotlin Multiplatform plugin directly integrate with, so why should you use this plugin?

  • No need to know how publishing works for different project types. AGP provides an API to configure publishing, java-library too, Kotlin Multiplatform does most things automatically but not everything. This plugin configures as much as possible on its own.
  • An unified approach for all kinds of projects. Some parts require manual configuration and for those we provide an API that works regardless of whether this is a Gradle plugin, an Android library or a Kotlin Multiplatform project. This is especially useful for projects that combine multiple of these.
  • Maven central integration. The plugin makes it easy to configure publishing to Maven Central with dedicated APIs to set it up and configure everything that is required. It also avoids issues like having multiple staging repositories on Sonatype OSS and supports automatic releasing without requiring any interaction with the web interface.
  • In memory GPG signing keys. Easily sign artifacts on CI by simply setting the required environment variables, no extra setup required.
  • Gradle property based config. Easily configure the plugin with Gradle properties that will apply to all subprojects
