Publish Maven artifacts with Azure Pipelines

Using Azure Pipelines, you can publish your Maven packages to Azure Artifacts feeds, public registries, or as a pipeline artifact.

Set up your project

  1. Add the following snippet to the repositories and distributionManagement sections in your pom.xml file. Replace the placeholders with your organization name, project name, and your feed name.

    <repository>
  <id>MavenDemo</id>
  <url>https://pkgs.dev.azure.com/ORGANIZATION-NAME/PROJECT-NAME/_packaging/FEED-NAME/maven/v1</url>
  <releases>
    <enabled>true</enabled>
  </releases>
  <snapshots>
    <enabled>true</enabled>
  </snapshots>
</repository>

  2. Configure your settings.xml file as follows. Replace the placeholders with your organization name, your project name, and your personal access token.

    <server>
  <id>PROJECT-NAME</id>
  <username>ORGANIZATION-NAME</username>
  <password>PERSONAL-ACCESS-TOKEN</password>
</server>

  3. Create a Personal Access Token with Packaging read & write scope and paste it into the password tag in your settings.xml file.

Build your code

In this example, we're using the Maven task to build the project with Azure Pipelines.

- task: Maven@3
  inputs:
    mavenPomFile: 'my-app/pom.xml'    // Path to your pom file
    mavenOptions: '-Xmx3072m'
    javaHomeOption: 'JDKVersion'
    jdkVersionOption: '1.8'
    jdkArchitectureOption: 'x64'
    publishJUnitResults: true
    testResultsFiles: '**/surefire-reports/TEST-*.xml'
    goals: 'package'

Publish packages to your pipeline

The following example illustrates how to publish your artifact to drop in your pipeline. Use the Copy files task to copy your packages to a target folder, then use Publish Build Artifacts to publish your build artifacts to Azure Pipelines.

- task: CopyFiles@2
  inputs:
    Contents: '**'
    TargetFolder: '$(build.artifactstagingdirectory)'
- task: PublishBuildArtifacts@1
  inputs:
    PathtoPublish: '$(Build.ArtifactStagingDirectory)'
    ArtifactName: 'drop'
    publishLocation: 'Container'

Publish packages to your feed

To publish your package to an Azure Artifacts feed, use the Maven task to deploy your artifact to your feed.

- task: Maven@3
  inputs:
    mavenPomFile: 'my-app/pom.xml'
    mavenOptions: '-Xmx3072m'
    javaHomeOption: 'JDKVersion'
    jdkVersionOption: '1.8'
    jdkArchitectureOption: 'x64'
    mavenAuthenticateFeed: true
    publishJUnitResults: false
    testResultsFiles: '**/surefire-reports/TEST-*.xml'
    goals: 'deploy'
