TeamCity Cloud 2022.10 Help

NuGet

Integration Capabilities

TeamCity integrates with NuGet package manager and, when NuGet is installed on agents, provides the following capabilities:

  • A set of NuGet runners to be used in builds on Windows OS, as well as on Linux and macOS when Mono is installed on the agent.

    • NuGet Installer build runner, which installs and updates NuGet packages.

    • NuGet Pack build runner, which builds NuGet packages.

    • NuGet Publish build runner, which publishes packages to a feed of your choice.

  • NuGet dependency trigger, which allows triggering builds on NuGet feed updates.

Supported Operating Systems:
NuGet build runners are supported on build agents running Windows OS by default. Linux and macOS are supported when Mono is installed on the agent (only NuGet 3.3+ on Mono 4.4.2+ is supported).

Typical Usage Scenarios

NuGet Packages Cache Clean-up on Agents

NuGet uses several local caches to avoid downloading packages that are already installed, and to provide offline support. If an agent is running out of the space, TeamCity will try to clean NuGet packages cache on the agent.

The TeamCity NuGet cleaner cleans caches in the following Windows directories:

  • %%NUGET_PACKAGES%% environment variable (must be an absolute path)

  • %%LOCALAPPDATA%%\NuGet\Cache

  • %%LOCALAPPDATA%%\NuGet\v3-cache

  • %%user.home%\.nuget\packages

Since TeamCity 2019.2.3, the new automatic package cleaner has been introduced in addition to the existing NuGet cleaner. If .NET SDK is installed on a build agent, TeamCity will use native .NET SDK commands for cleaning. The new cleaner works across all platforms supporting .NET SDK and operates on several levels. It cleans the temporary cache first, and only then gets to cleaning the .nupkg files and HTTP requests, if necessary.

Authentication in private NuGet Feeds

You can use authentication in the feeds specified in the NuGet feed credentials build feature. The credentials' provider will automatically authenticate requests to these feeds.
