When developing applications in a larger project, you may find a need to share common libraries across multiple teams or applications. If this library is a public OSS library, it's usually hosted on Maven Central. For an internal library, though, you'll need to use a private repository. Typically, in an on-premise datacenter, these Java (Maven) artifacts may be stored in private repositories such as Sonatype Nexus, or JFrog Artifactory.
Artifact Registry is a fully managed artifact repository service - you can use it to store container images, NPM packages, and Java artifacts, without having to setup any infrastructure and worry about availably or disk space.
gcloud services enable artifactregistry.googleapis.com
Artifact Registry can host Maven repositories to host the Java artifacts. Artifacts are hosted within a region of your choice, and you can apply Identity Access Management to control who can access/update artifacts.
Artifact Registry is currently in beta, and the Maven Repository feature is in Alpha. You'll need to sign up for the Alpha program first.
Once you are confirmed to be enrolled in the alpha program, you can give it a try!
gcloud beta artifacts repositories create private-maven-repo \
gcloud beta artifacts packages list \
There should be no artifacts at the moment.
You need to update the build configuration (e.g.,
pom.xml) in order to configure an artifact to Artifact Registry's Maven repository. You can find the full configuration needed through by running the utility command:
This example will use Maven. First, create a brand new Maven project:
mvn archetype:generate \
Once you have a Java project you want to publish to Artifact Registry, then you can use
gcloudCLI to print out the configuration for your build system (Maven or Gradle). You'll need to use the configuration to be able to publish artifacts to the repository, or consume artifacts from the repository.
gcloud beta artifacts print-settings mvn \
Note that an Artifact Registry Wagon extension is needed to publish to Artifact Registry.
gcloud beta artifacts print-settings gradle \
Note that an Artifact Registry Gradle plugin is needed to publish to Artifact Registry.
This example uses Maven, so edit the
pom.xmlto add the additional settings:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
<!-- Add Distributuion Management -->
<!-- Add Repository -->
<!-- Add the Wagon Extension -->
mvn clean package deploy
Verify that the artifact is published!
gcloud alpha artifacts packages list \
In the Cloud Console, you can also browse to Artifact Registry > private-maven-repo.
And see manage the artifacts:
