为什么我的 Azure Pipeline 作业失败并显示错误 NU1101？

Question

我正在 Azure DevOps 中运行 CD/CI 管道，最近我的管道作业开始失败并出现以下错误：

##[error]Error: The process 'C:\Program Files\dotnet\dotnet.exe' failed with exit code 1
##[warning]Info: Azure Pipelines hosted agents have been updated to contain .Net Core 3.x (3.0 and 3.1) SDK/Runtime along with 2.1.
Unless you have locked down a SDK version for your project(s), 3.x SDK
might be picked up which might have breaking behavior as compared to
previous versions. 
Some commonly encountered changes are: 
If you're using `Publish` command with -o or --Output argument, you will see that the output folder is now being created at root
directory rather than Project File's directory. To learn about more
such changes and troubleshoot, refer here:

##[error]Dotnet command failed with non-zero exit code on the following projects : D:\a\1\s\MyProject\MyProject.UI.csproj

除上述内容外，还有与资源位置有关的错误：

我在这里注意到的是，它正在寻找Microsoft Visual Studio Offline Packages这些包，我不确定为什么或者这是否可以接受。本地解决方案构建良好，只有在我们尝试在管道上构建时才会发生这些错误。研究错误带来了几个选项，但都没有奏效。

• 我尝试的第一件事是清除我的包缓存并更新我的源，这并没有改变任何东西。
• 然后我更新了这些来源，但同样，这并没有改变任何东西。

我的应用程序正在使用.NET Core 3.1.101并且完全是最新的。我定义了三个包源NuGet，Microsoft Visual Studio Offline、 和Telerik。

这是我的nuget.config文件：

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <packageRestore>
    <add key="enabled" value="True" />
    <add key="automatic" value="True" />
  </packageRestore>
  <activePackageSource>
    <add key="All" value="(Aggregate source)" />
  </activePackageSource>
  <packageSources>
    <add key="NuGet" value="https://api.nuget.org/v3/index.json" />
    <add key="Telerik" value="https://nuget.telerik.com/nuget" />
    <add key="MyGet" value="https://www.myget.org/F/sixlabors/api/v3/index.json" />
  </packageSources>
<packageSourceCredentials>   
    <Telerik>
      <add key="Username" value="xxx" />
      <add key="ClearTextPassword" value="xxx" />
    </Telerik>
  </packageSourceCredentials>  
</configuration>

我不久前建立的管道和可能导致问题的一个区域看起来像这样，我很高兴收到有关此的反馈：

# Add steps that publish symbols, save build artifacts, and more:
# https://docs.microsoft.com/azure/devops/pipelines/languages/dotnet-core

    publishWebProjects: true
    arguments: '--configuration $(buildConfiguration) --output $(Build.artifactStagingDirectory)'
    zipAfterPublish: true

    platform: '$(buildPlatform)'
    configuration: '$(buildConfiguration)'

- task: VSTest@2
  inputs:
    platform: '$(buildPlatform)'
    configuration: '$(buildConfiguration)'

所以，这是一个我无法确定的令人沮丧的问题，希望有人能帮助我深入了解它。

更新

只是一些额外的背景下加入到我的问题，我的解决方案分为MyProject.Repo，MyProject.Services，MyProject.Data和MyProject.UI。

就这些目标框架而言，它们如下：

• MyProject.Repo（类库）- .NET Standard 2.1
• MyProject.Services（类库）- .NET Standard 2.1
• MyProject.Data（类库）- .NET Standard 2.1
• MyProject.UI - .NET Core 3.1

构建在工作中失败 DotNetCoreCLI

Answer 1

错误 NU1101：无法找到包 Microsoft.AspNetCore.Mvc.Core。源中不存在具有此 ID 的包：Microsoft Visual Studio 离线包。

根据错误消息，在 Private Nuget 资源中找不到该包。这些包存在于nuget.org 中。

为此，您可以尝试在“dotnet 发布”任务之前添加“dotnet restore ”任务。然后你可以在任务中引用 nuget.config 文件。

例如：

- task: DotNetCoreCLI@2
  displayName: 'dotnet restore'
  inputs:
    command: restore
    projects: '**/*.csproj'
    feedsToUse: config
    nugetConfigPath: 'nuget.config'

希望这可以帮助。
