Working with the NuGet registry

You can configure the dotnet command-line interface (CLI) to publish NuGet packages to GitHub Package Registry and to use packages stored on GitHub Package Registry as dependencies in a .NET project.

GitHub Package Registry está disponível com GitHub Free, GitHub Pro, GitHub Free para organizações, GitHub Team, GitHub Enterprise Cloud, GitHub Enterprise Server e GitHub AE.


O GitHub Package Registry não está disponível para repositórios privados de contas que utilizam planos antigos por-repositório. Além disso, as contas que usam os planos de legado por repositório não podem acessar o Container registry já que essas contas são cobradas por repositório. Para obter mais informações, consulte os "[produtos do GitHub](/articles/github-s-products)".

Authenticating to GitHub Package Registry

Você precisa de um token de acesso para publicar, instalar e excluir pacotes no GitHub Package Registry.

Você pode usar um token de acesso pessoal (PAT) para efetuar a autenticação em GitHub Package Registry ou na API de GitHub Ao criar um token de acesso pessoal, você pode atribuir diferentes escopos de token, dependendo da sua necessidade. Para obter mais informações sobre os escopos dos pacotes para um PAT, consulte "Sobre permissões para o GitHub Packages."

Para efetuar a autenticação em um registro do GitHub Package Registry dentro de um fluxo de trabalho de GitHub Actions, você pode utilizar:

  • GITHUB_TOKEN para publicar pacotes associados ao repositório do fluxo de trabalho.
  • um PAT para instalar pacotes associados a outros repositórios privados (que o GITHUB_TOKEN não consegue acessar).

Authenticating with GITHUB_TOKEN in GitHub Actions

Use the following command to authenticate to GitHub Package Registry in a GitHub Actions workflow using the GITHUB_TOKEN instead of hardcoding a token in a nuget.config file in the repository:

dotnet nuget add source --username USERNAME --password ${{ secrets.GITHUB_TOKEN }} --store-password-in-clear-text --name github "https://nuget.pkg.github.com/OWNER/index.json"

Para obter mais informações sobre GITHUB_TOKEN usado nos fluxos de trabalho de GitHub Actions, consulteAutenticação em um fluxo de trabalho".

Authenticating with a personal access token

Você deve usar um token de acesso pessoal com os escopos apropriados para publicar e instalar pacotes no GitHub Package Registry. Para obter mais informações, consulte "Sobre GitHub Package Registry."

To authenticate to GitHub Package Registry with the dotnet command-line interface (CLI), create a nuget.config file in your project directory specifying GitHub Package Registry as a source under packageSources for the dotnet CLI client.

You must replace:

  • USERNAME with the name of your user account on GitHub.
  • TOKEN with your personal access token.
  • OWNER with the name of the user or organization account that owns the repository containing your project.
<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <packageSources>
        <clear />
        <add key="github" value="https://nuget.pkg.github.com/OWNER/index.json" />
    </packageSources>
    <packageSourceCredentials>
        <github>
            <add key="Username" value="USERNAME" />
            <add key="ClearTextPassword" value="TOKEN" />
        </github>
    </packageSourceCredentials>
</configuration>

Publishing a package

You can publish a package to GitHub Package Registry by authenticating with a nuget.config file, or by using the --api-key command line option with your GitHub personal access token (PAT).

Publishing a package using a GitHub PAT as your API key

If you don't already have a PAT to use for your GitHub account, see "Creating a personal access token."

  1. Create a new project.

    dotnet new console --name OctocatApp
  2. Package the project.

    dotnet pack --configuration Release
  3. Publish the package using your PAT as the API key.

    dotnet nuget push "bin/Release/OctocatApp.1.0.0.nupkg"  --api-key YOUR_GITHUB_PAT --source "github"

Após publicar um pacote, você poderá visualizá-lo no GitHub. Para obter mais informações, consulte "Visualizar pacotes".

Publishing a package using a nuget.config file

When publishing, you need to use the same value for OWNER in your csproj file that you use in your nuget.config authentication file. Specify or increment the version number in your .csproj file, then use the dotnet pack command to create a .nuspec file for that version. For more information on creating your package, see "Create and publish a package" in the Microsoft documentation.

  1. Autenticar para GitHub Package Registry. Para obter mais informações, consulte "Authenticating to GitHub Package Registry."

  2. Create a new project.

    dotnet new console --name OctocatApp
  3. Add your project's specific information to your project's file, which ends in .csproj. You must replace:

    • OWNER with the name of the user or organization account that owns the repository containing your project.
    • REPOSITORY with the name of the repository containing the package you want to publish.
    • 1.0.0 with the version number of the package.
    <Project Sdk="Microsoft.NET.Sdk">
    
      <PropertyGroup>
        <OutputType>Exe</OutputType>
        <TargetFramework>netcoreapp3.0</TargetFramework>
        <PackageId>OctocatApp</PackageId>
        <Version>1.0.0</Version>
        <Authors>Octocat</Authors>
        <Company>GitHub</Company>
        <PackageDescription>This package adds an Octocat!</PackageDescription>
        <RepositoryUrl>https://github.com/OWNER/REPOSITORY</RepositoryUrl>
      </PropertyGroup>
    
    </Project>
    
  4. Package the project.

    dotnet pack --configuration Release
  5. Publish the package using the key you specified in the nuget.config file.

    dotnet nuget push "bin/Release/OctocatApp.1.0.0.nupkg" --source "github"

Após publicar um pacote, você poderá visualizá-lo no GitHub. Para obter mais informações, consulte "Visualizar pacotes".

Publishing multiple packages to the same repository

To publish multiple packages to the same repository, you can include the same GitHub repository URL in the RepositoryURL fields in all .csproj project files. GitHub matches the repository based on that field.

For example, the OctodogApp and OctocatApp projects will publish to the same repository:

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>netcoreapp3.0</TargetFramework>
    <PackageId>OctodogApp</PackageId>
    <Version>1.0.0</Version>
    <Authors>Octodog</Authors>
    <Company>GitHub</Company>
    <PackageDescription>This package adds an Octodog!</PackageDescription>
    <RepositoryUrl>https://github.com/octo-org/octo-cats-and-dogs</RepositoryUrl>
  </PropertyGroup>

</Project>
<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>netcoreapp3.0</TargetFramework>
    <PackageId>OctocatApp</PackageId>
    <Version>1.0.0</Version>
    <Authors>Octocat</Authors>
    <Company>GitHub</Company>
    <PackageDescription>This package adds an Octocat!</PackageDescription>
    <RepositoryUrl>https://github.com/octo-org/octo-cats-and-dogs</RepositoryUrl>
  </PropertyGroup>

</Project>

Installing a package

Using packages from GitHub in your project is similar to using packages from nuget.org. Add your package dependencies to your .csproj file, specifying the package name and version. For more information on using a .csproj file in your project, see "Working with NuGet packages" in the Microsoft documentation.

  1. Autenticar para GitHub Package Registry. Para obter mais informações, consulte "Authenticating to GitHub Package Registry."

  2. To use a package, add ItemGroup and configure the PackageReference field in the .csproj project file, replacing the OctokittenApp package with your package dependency and 1.0.0 with the version you want to use:

    <Project Sdk="Microsoft.NET.Sdk">
    
      <PropertyGroup>
        <OutputType>Exe</OutputType>
        <TargetFramework>netcoreapp3.0</TargetFramework>
        <PackageId>OctocatApp</PackageId>
        <Version>1.0.0</Version>
        <Authors>Octocat</Authors>
        <Company>GitHub</Company>
        <PackageDescription>This package adds an Octocat!</PackageDescription>
        <RepositoryUrl>https://github.com/OWNER/REPOSITORY</RepositoryUrl>
      </PropertyGroup>
    
      <ItemGroup>
        <PackageReference Include="OctokittenApp" Version="12.0.2" />
      </ItemGroup>
    
    </Project>
    
  3. Install the packages with the restore command.

    dotnet restore

Troubleshooting

Your NuGet package may fail to push if the RepositoryUrl in .csproj is not set to the expected repository .
