Nexus Publish Plugin

Gradle Plugin that explicitly creates a Staging Repository before publishing to Nexus. This solves the problem that frequently occurs when uploading to Nexus from Travis, namely split staging repositories.

⚠️ Deprecation 🛑

This plugin is now deprecated and no longer maintained. The Gradle Nexus Publish Plugin is the successor of this plugin and adds additional tasks to close and release staging repositories.

Usage

The plugin does the following:

• Apply the maven-publish plugin
• configure a Maven artifact repository for each repository defined in the nexusPublishing { repositories { ... } } block
• create a initialize${repository.name.capitalize()}StagingRepository task that starts a new staging repository in case the project's version does not end with -SNAPSHOT (customizable via the useStaging property) and sets the URL of the corresponding Maven artifact repository accordingly. In case of a multi-project build, all subprojects with the same nexusUrl will use the same staging repository.
• if the io.codearte.nexus-staging plugin is applied on the root project, the stagingRepositoryId on its extension is set to the id of the newly created staging repository, this way it does not depend on exactly one open staging repository being available.
• make all publishing tasks for each configured repository depend on the initialize${repository.name.capitalize()}StagingRepository task.
• create a publishTo${repository.name.capitalize()} lifecycle task that depends on all publishing tasks for the corresponding Maven artifact repository.

Publishing to Maven Central via Sonatype OSSRH

In order to publish to Maven Central via Sonatype's OSSRH Nexus, you simply need to add the sonatype() repository like in the example below. It's nexusUrl and snapshotRepositoryUrl are pre-configured.

nexusPublishing {
    repositories {
        sonatype()
    }
}

In addition, you need to set the sonatypeUsername and sonatypePassword project properties, e.g. in ~/.gradle/gradle.properties. Alternatively, you can configure username and password in the sonatype block:

nexusPublishing {
    repositories {
        sonatype {
            username = "your-username"
            password = "your-password"
        }
    }
}

Finally, call publishToSonatype to publish all publications to Sonatype's OSSRH Nexus.

            nexusUrl = uri("https://your-server.com/staging")
            snapshotRepositoryUrl = uri("https://your-server.com/snapshots")
            username = "your-username" // defaults to project.properties["myNexusUsername"]
            password = "your-password" // defaults to project.properties["myNexusPassword"]
        }
    }
}

publishing {
    publications {
        create<MavenPublication>("mavenJava") {
            from(components["java"])
        }
    }
}

nexusPublishing {
    repositories {
        create("myNexus") {
            nexusUrl.set(uri("https://your-server.com/staging"))
            snapshotRepositoryUrl.set(uri("https://your-server.com/snapshots"))
            username.set("your-username") // defaults to project.properties["myNexusUsername"]
            password.set("your-password") // defaults to project.properties["myNexusPassword"]
        }
    }
}

Integration with the Nexus Staging Plugin

If the io.codearte.nexus-staging plugin is applied on the root project, the following default values change:

This reuses the values specified for the nexusStaging block, so you don't have to specify them twice.

HTTP Timeouts

You can configure the connectTimeout and clientTimeout properties on the nexusPublishing extension to set the connect and read/write timeouts (both default to 1 minute). Good luck!
