🔗 Integration

Integration with Vanniktech Maven Publish Plugin

The Gradle Maven Publish Plugin (vanniktech) is a popular choice for publishing Android and Kotlin libraries to Maven Central, JCenter, and Nexus repositories.

Maven Central utility plugins for Gradle works seamlessly with it, eliminating the need to duplicate POM configurations across modules.

import io.github.yonggoose.organizationdefaults.OrganizationDefaults

plugins {
    id("java")
    id("io.github.yonggoose.maven.central.utility.plugin..project") version "0.1.6"
    id("com.vanniktech.maven.publish") version "0.34.0"
    id("maven-publish")
}

rootProjectPom {
    groupId = "io.github.yonggoose"
    artifactId = "organization-defaults"
    version = "1.0.0"
    ...
}

afterEvaluate {
    val mergedPom = project.extensions.extraProperties.get("mergedDefaults") as OrganizationDefaults

    mavenPublishing {
        coordinates(
            groupId = mergedPom.groupId,
            artifactId = mergedPom.artifactId,
            version = mergedPom.version
        )

        pom {
            name.set(mergedPom.name)
            description.set(mergedPom.description)
            url.set(mergedPom.url)
            ...
        }
    }
}

This integration shows how centralized POM management from Maven Central utility plugins for Gradle can be directly reused inside vanniktech-maven-publish, making your publishing workflow cleaner and less error-prone.
