Gradle with Local Archiva Publish

This shows the way to get gradle to use a local Archiva server to publish your project artifacts.

IMPORTANT: You must configure your “guest” user in Archiva to have the correct permissions (roles) to publish to the Archiva server. To do this, in the Archiva WebUI (the default is http://localhost:8080), on the left side under “USERS”, click “Manage”, then click the blue pencil next to “guest”, then click the “Edit Roles” (next to the blue “Edit” button), then checkbox select “Global Repository Manager” and “Global Repository Observer” and press Update.

Interesting fact: Archiva will accept “SNAPSHOT” artifacts into its “internal” repository (i.e. the upload will succeed, and Archiva will store the artifacts in its “/repositories/internal/” directory). BUT it will not serve these artifacts, saying instead “managed repo is configured for release only”. If you accidentally publish SNAPSHOT artifacts to the “internal” repository, then you’ll have to clean your “/repositories/internal/” directory by hand – the WebUI won’t let you.

So, given that interesting fact, the “if” logic (below) looks for “SNAPSHOT” and sets the url to the correct location. Note that the single “maven { }” entry is different from how it was configured for resolving, where there were two entries. (See Gradle with Local Archiva).

This shows the correct ‘publishing’ section of your build.gradle file for publishing to your local Archiva server. This also shows how to publish your “-sources” artifact. Feel free to substitute “localhost” for the actual machine name or IP address of your Archiva server.

(2014/6/10 update: added ext.isReleaseVersion and added checks before using the .publishBaseUrl property before using it.)

Versions:
archiva: 2.0.1
gradle: 1.11

// Used in publishing - the new plugin:
apply plugin: 'maven-publish'

// Used in publishing - pom information: 
group =  'com.tiemens'
version =  '0.1-SNAPSHOT'
project.ext.isReleaseVersion = !version.endsWith("SNAPSHOT")

// Used in publishing - source artifact: 
task sourceJar(type: Jar) {
    from sourceSets.main.allJava
}

publishing {
    publications {
        mavenJava(MavenPublication) {

            from components.java

            artifact sourceJar {
                classifier "sources"
            }
        }
    }

    repositories {
        maven {
            if (project.hasProperty('publishBaseUrl')) {
                if (! project.ext.isReleaseVersion) {
                    url project.publishBaseUrl + "/snapshots"
                } else {
                    url project.publishBaseUrl + "/internal"
                }
            } else {
                    // this is a notice that 'publish' requires .publishBaseUrl
                    url "http://you.must.configure.project.publishBaseUrl"
            }
        }
    }

}

Just for documentation, this shows the error message you get if you don’t set up your guest user with the proper roles.
