Publish Maven artifacts with Azure Pipelines (YAML/Classic)

Using Azure Pipelines, you can publish your Maven artifacts to Azure Artifacts feeds in your organization, in other organizations, and to public registries such as Maven Central. This article will guide you through publishing your Maven artifacts using both YAML and Classic pipelines.

Prerequisites

• An Azure DevOps organization. Create one for free.

• An Azure DevOps project. Create a new project if you don't have one already.

• An Azure Artifacts feed. Create one for free.

Publish packages to a feed in the same organization

YAML

1. Sign in to your Azure DevOps organization, and then navigate to your project.

2. Select Pipelines, and then select your pipeline definition.

3. Select Edit, and then add the following snippet to your YAML pipeline.

steps:
- task: MavenAuthenticate@0
  displayName: 'Authenticate to Azure Artifacts feed'
  inputs:
    artifactsFeeds: 'MavenDemo,MavenDemoFeed2'        ## Select one or multiple feeds to authenticate with.
- script: |
   mvn deploy
  displayName: 'Publish'

Classic

1. Sign in to your Azure DevOps organization, and then navigate to your project.

2. Select Pipelines, and then select your pipeline definition.

3. Select Edit, and then select the + sign to add a new task. Add the Maven Authenticate and Command line tasks to your pipeline definition and configure them as follows:

   1. Maven Authenticate: Select one or multiple feeds from the Feeds dropdown menu.

   2. Command line task:

      • Display name: Publish.
      • Script:

        mvn deploy
        

4. Select Save & queue when you're done.

Publish packages to a feed in another organization

To publish your packages to a feed in another Azure DevOps organization, you must first create a personal access token in the target organization.

Navigate to the organization hosting your target feed and Create a personal access token with Packaging > Read & write scope. Copy your personal access token as you'll need it in the following section.

Create a service connection

1. Sign in to the Azure DevOps organization where your pipeline will run, and then navigate to your project.

2. Navigate to your Project settings > Service connections.

3. Select New service connection, select Maven, and then select Next.

4. Select Username and Password as the Authentication method, and then enter your Repository URL and your Repository Id.

5. Enter your Username (a placeholder, as Azure Pipelines will use your pom.xml configuration file and the personal access token you created earlier to authenticate). For Password, paste your personal access token. Provide a Name for your service connection, and check the Grant access permission to all pipelines checkbox.

6. Select Save when you're done.
