Azure Devops 上的 Nuget 还原失败并显示消息“无法加载源的服务索引" [英] Nuget restore fails on Azure Devops with message "unable to load the service index for source"

问题描述

我有一个在私有代理中运行的 .NET 解决方案的构建.该解决方案包含 .NET Core 2.1 和 .NET Standard 2.0 项目.

安装的一些 nuget 包如下:

• NETStandard.Library v2.0.3
• Microsoft.AspNetCore.Mvc v2.0.0
• Microsoft.NETCore.App v2.1.5

尝试恢复 nuget 包时构建失败，并显示以下错误:

<块引用>

"F:Agent01w141sxxxxxxx.sln" (恢复目标) (1) ->(恢复目标)->C:Program Filesdotnetsdk2.1.500NuGet.targets(114,5): 错误:无法加载源

这是构建代理中%appdata%NuGet uget.config文件的内容:

我已经检查了一些类似的问题，但到目前为止我还没有找到解决我的问题的方法.

一些注意事项:

• 个人访问令牌未过期
• 此特定构建在其他构建代理中成功运行
• 至少有 1 个带有nuget restore"任务的构建使用此代理成功运行(常规 nuget restore 任务，而不是 .NET Core)
• 尝试重新启动构建代理，但没有成功
• 在恢复之前尝试

  更新 2:

  我能够使用 .NET Core 任务 v1 恢复包:

  还原包

  或者使用带有参数 --force 的 v2 任务:

  恢复软件包

  解决方案

  我找到了解决方案 - 将以下包源添加到 %appdata%NuGet uget.config:

  <add key="Microsoft Visual Studio Offline Packages" value="C:Program Files (x86)Microsoft SDKsNuGetPackages"/>

  完整的文件如下所示:

  另外，检查 回归 .NET SDK 500: 'dotnet tool install' failed with 401 (Unauthorized) 当 NuGet.config #7524 中有私人提要时.此问题似乎是由 .NET SDK 2.1.500 引起的.

  另一种解决方法是卸载该版本:

  该问题在 .NET Core SDK 2.1.400 中不存在，例如它消失了.NET Core SDK 2.1.500 卸载后，SDK 重新出现2.1.500 再次安装.

  I have a build for a .NET solution that is running in a private agent. The solution contains both .NET Core 2.1 and .NET Standard 2.0 projects.

  Some of the nuget packages installed are the following:

  • NETStandard.Library v2.0.3
  • Microsoft.AspNetCore.Mvc v2.0.0
  • Microsoft.NETCore.App v2.1.5

  The build fails when trying to restore the nuget packages with the following error:

  "F:Agent01w141sxxxxxxx.sln" (Restore target) (1) -> (Restore target) -> C:Program Filesdotnetsdk2.1.500NuGet.targets(114,5): error : Unable to load the service index for source https://xxxxxxxxxx.pkgs.visualstudio.com/_packaging/xxxxxxxxxx/nuget/v3/index.json. C:Program Filesdotnetsdk2.1.500NuGet.targets(114,5): error : Response status code does not indicate success: 401 (Unauthorized).

  Build task is the following:

  This is the content of %appdata%NuGet uget.config file in the build agent:

  <?xml version="1.0" encoding="utf-8"?>
  <configuration>
    <packageSources>
      <add key="nuget.org" value="https://api.nuget.org/v3/index.json" />
      <add key="MyFeed" value="https://xxxxxxxxxx.pkgs.visualstudio.com/_packaging/xxxxxxxxxx/nuget/v3/index.json" />
    </packageSources>
    <packageSourceCredentials>
      <MyFeed>
        <add key="Username" value="LocalBuildAgent" />
        <add key="ClearTextPassword" value="xxxxxxxxxxx" />
      </MyFeed>
    </packageSourceCredentials>
  </configuration>
  

  I already checked a few similar questions but so far I wasn't able to find a solution for my problem.

  Some notes:

  • Personal Access Token is NOT expired
  • This particular build runs successfully in other build agents
  • There is at least 1 build with a "nuget restore" task that was run successfully using this agent (regular nuget restore task, NOT .NET Core)
  • Tried restarting the build agent, without success
  • Tried specifying a specific version of nuget before the restore, without success
  • .NET Core SDK latest version in the build agent is 2.1.500 (multiple versions installed)

  What am I missing? How to fix this issue? Why can't I restore the packages using the dotnet restore command?

  UPDATE:

  Packages are restored without errors when using the old Nuget Restore task as follows:

  UPDATE 2:

  I am able to restore the packages using the .NET Core task v1:

  Or using v2 task with argument --force:

  解决方案

  I found a solution - add the following package source to %appdata%NuGet uget.config:

  <add key="Microsoft Visual Studio Offline Packages" value="C:Program Files (x86)Microsoft SDKsNuGetPackages" />
  

  Complete file looks like this:

  <?xml version="1.0" encoding="utf-8"?>
  <configuration>
    <packageSources>
      <add key="Microsoft Visual Studio Offline Packages" value="C:Program Files (x86)Microsoft SDKsNuGetPackages" />
      <add key="nuget.org" value="https://api.nuget.org/v3/index.json" />
      <add key="MyFeed" value="https://xxxxxxxxxx.pkgs.visualstudio.com/_packaging/xxxxxxxxxx/nuget/v3/index.json" />
    </packageSources>
    <packageSourceCredentials>
      <MyFeed>
        <add key="Username" value="LocalBuildAgent" />
        <add key="ClearTextPassword" value="xxxxxxxxxxx" />
      </MyFeed>
    </packageSourceCredentials>
  </configuration>
  

  Also, check Regression in .NET SDK 500: 'dotnet tool install' fails with 401 (Unauthorized) when there is a private feed in NuGet.config #7524. This problem seems to be caused by .NET SDK 2.1.500.

  Another workaround would be to uninstall that version:

  The issue is not present in .NET Core SDK 2.1.400, e.g. it goes away when .NET Core SDK 2.1.500 is uninstalled, and reappears when SDK 2.1.500 is installed again.
