Publish and download Universal Packages with Azure Pipelines

Azure DevOps Services

Universal Packages allow you to package any number of files of any type and share them with your team. Using the Universal Package task in Azure Pipelines, you can pack, publish, and download packages of various sizes, up to 4 TB. Each package is uniquely identified with a name and a version number. You can use Azure CLI or Azure Pipelines to publish and consume packages from your Artifacts feeds.

Note

Universal Packages are only available in Azure DevOps Services.

Copy files

The Universal Packages task in Azure Pipelines is set to use $(Build.ArtifactStagingDirectory) as the default publish directory. To ready your Universal Package for publishing, move the files you wish to publish to that directory. You can also use the Copy Files utility task to copy those files to the publish directory.

Publish a Universal Package

To publish a Universal Package to your Azure Artifacts feed, add the following task to your pipeline's YAML file.

- task: UniversalPackages@0
  displayName: Publish a Universal Package
  inputs:
    command: publish
    publishDirectory: '$(Build.ArtifactStagingDirectory)'
    vstsFeedPublish: '<projectName>/<feedName>'
    vstsFeedPackagePublish: '<Package name>'
    packagePublishDescription: '<Package description>'
Argument Description
publishDirectory Location of the files you wish to publish.
vstsFeedPublish The project and feed name to publish to. If you're working with an organization-scoped feed, specify only the feed name.
vstsFeedPackagePublish The package name. Must be lower case. Use only letters, numbers, and dashes.
packagePublishDescription Description of the package content.

To publish packages to an Azure Artifacts feed from your pipeline, the pipeline identity must have the Feed Publisher (Contributor) role on the feed. For more information, see Pipelines permissions.

To publish to an external feed, you must first create a service connection to authenticate with your feed. For more information, see Manage service connection.

Package versioning

Universal Packages follow the semantic versioning specification and can be identified by their names and version numbers. Semantic version numbers are composed of three numeric components, Major, Minor, and Patch, in the format: Major.Minor.Patch.

The minor version number is incremented when new features are added that are backward compatible with previous versions, in this case, you increment the minor version and reset the patch version to 0 (1.4.17 to 1.5.0). The major version number is incremented when there are significant changes that could break compatibility with previous versions. In this case, you increment the major version and reset the minor and patch versions to 0 (2.6.5 to 3.0.0). The patch version number should be incremented when only bug fixes or other small changes are made that don't affect compatibility with previous versions (1.0.0 to 1.0.1).

When publishing a new package, the Universal Packages task will automatically select the next major, minor, or patch version for you.

To enable versioning for your package, add a versionOption input to your YAML file. The options for publishing a new package version are: major, minor, patch, or custom.

Selecting custom enables you to manually specify your package version. The other options get the latest package version from your feed and increment the chosen version segment by 1. So if you have a testPackage 1.0.0, and select the major option, your new package will be testPackage 2.0.0. If you select the minor option, your package version will be 1.1.0, and if you select the patch option, your package version will be 1.0.1.

If you choose the custom option, you must also specify a versionPublish value as follows:

- task: UniversalPackages@0
  displayName: Publish a Universal Package
  inputs:
    command: publish
    publishDirectory: '$(Build.ArtifactStagingDirectory)'
    vstsFeedPublish: '<projectName>/<feedName>'
    vstsFeedPackagePublish: '<Package name>'
    versionOption: custom
    versionPublish: '<Package version>'
    packagePublishDescription: '<Package description>'
Argument Description
publishDirectory Location of the files you wish to publish.
vstsFeedPublish The project and feed name to publish to. If you're working with an organization-scoped feed, specify only the feed name.
vstsFeedPackagePublish The package name. Must be lower case. Use only letters, numbers, and dashes.
versionOption Select a versioning strategy. Options: major, minor, patch, custom.
versionPublish The custom package version.
packagePublishDescription Description of the package content.

Download a Universal Package

To download a Universal Package from a feed in your organization, use the Universal Package task with the download command as follows:

- task: UniversalPackages@0
  displayName: Download a Universal Package
  inputs:
    command: download
    vstsFeed: '<projectName>/<feedName>'
    vstsFeedPackage: '<packageName>'
    vstsPackageVersion: '<packageVersion>'
    downloadDirectory: '$(Build.SourcesDirectory)\someFolder'
Argument Description
vstsFeed The Artifacts feed hosting the package to be downloaded.
vstsFeedPackage Name of the package to be downloaded.
vstsPackageVersion Version of the package to be downloaded.
downloadDirectory The package destination folder. Default value: $(System.DefaultWorkingDirectory).

To download a Universal Package from an external source, use the following snippet:
