Why Publish at All

Once your shared module is solid, other teams want to reuse it. Publishing turns your code into a versioned artifact they can simply depend on. 📦

Meet maven-publish

The maven-publish Gradle plugin packages your build outputs into artifacts and writes the metadata repositories expect.

plugins {
    kotlin("multiplatform")
    id("maven-publish")
}

KMP Publishes Many Artifacts

A KMP library is not one JAR. Each target gets its own artifact, plus a shared metadata module that ties them together.

The Root Metadata Module

The metadata module is the entry point consumers actually request. Gradle then resolves the right per-platform artifact behind it.

Coordinates Identify You

Every artifact needs coordinates: a group, an artifact name, and a version. Together they form the unique address others depend on.

group = "com.coddykit.shared"
version = "1.0.0"

Declare a Repository

Tell Gradle where artifacts go using a publishing block. A local folder is perfect for testing before any remote release.

publishing {
    repositories {
        maven { url = uri(layout.buildDirectory.dir("repo")) }
    }
}

Run the Publish Task

The plugin adds Gradle tasks for you. Running publish builds every target and copies all artifacts into your chosen repository.

./gradlew :shared:publish

Add POM Metadata

The POM describes your library: name, description, and license. Public repositories require this so users know what they are pulling in.

pom {
    name.set("Shared KMP")
    description.set("Shared logic for both apps")
}

Test Locally First

Publish to your mavenLocal cache, then add it as a dependency in a sample app. This proves the artifact resolves before you go public.

./gradlew :shared:publishToMavenLocal

Sources and Docs Jars

Ship a sources jar so consumers can read your code in their IDE. A docs jar adds the generated reference for an even better experience.

Keep Versions Honest

Bump the version on every release. Republishing the same version with new code breaks builds that already cached the old artifact.

Quick Check

Let's check how KMP publishing works.

Recap

Apply maven-publish, set coordinates, add a repository and POM, then publish locally to test before any real release. 🎉
