无法在Azure管道中使用Paket恢复NuGet包(工件提要)

Question

我试图定义一个为.NET Core解决方案构建的管道。依赖项由Paket管理。依赖项从Azure工件提要中下载。

在第一阶段，我认为问题是Paket，我能够定义一个不用它构建的管道(使用私有包源，我们的私有提要)。

一旦我修复了Paket问题，我就会遇到一些问题，试图让dotnet restore工作起来。

这是我实际的YML定义：

trigger:
- none

pool:
  vmImage: 'windows-latest'

steps:
  - task: UseDotNet@2
    inputs:
      packageType: 'sdk'
      version: '3.1.x'

  - powershell: |
      cd ..
      dotnet tool install -g paket

  - task: setCredentialManager@0

  - task: PaketRestore@0
    inputs:
      PaketPath: '.paket'

  - task: paketCredentialCleanup@0

  # I'm not sure the following task is necessary
  - task: PowerShell@2
    inputs:
      filePath: './installcredprovider.ps1'

  - task: NuGetCommand@2
    inputs:
      command: 'restore'
      restoreSolution: '**/*.sln'
      feedsToUse: 'config'
      nugetConfigPath: './NuGet.config'

  - task: CmdLine@2
    inputs:
      script: 'dotnet restore'

  - task: DotNetCoreCLI@2
    inputs:
      command: 'build'
      projects: '*.csproj'

NuGetCommand@2还原任务在此日志中失败：

无论如何，忽略它，dotnet restore也会失败。

脚本installcredprovider.ps1的来源是这里。

存储库可以从这里下载(提要URL被部分混淆)。

提前感谢任何想帮忙的人！

我创建了一个用于故障排除的测试项目。我发现帕克特需要.NET Core sdk 2.0.0。

如果未安装DotNetCore2.0.0，则Nuget还原任务将因上述错误"It was not possible to find any compatible framework version"而失败。如果错误The framework 'Microsoft.NETCore.App', version '2.0.0' was not found.，那么paket任务就会失败。

在安装了带有.NET Core sdk 2.0.0的UseDotNet任务之后。Nuget还原和paket还原都成功运行。请查看以下yaml：

pool:
  vmImage: 'windows-latest'

steps:

  - task: UseDotNet@2
    inputs:
      packageType: 'sdk'
      version: '2.0.0'

  - task: UseDotNet@2
    inputs:
      packageType: 'sdk'
      version: '3.1.x'

  - powershell: |
      cd ..
      dotnet tool install -g paket

  - task: setCredentialManager@0

  - task: PaketRestore@0
    inputs:
      PaketPath: '.paket'

  - task: paketCredentialCleanup@0

  # - task: PowerShell@2
  #   inputs:
  #     filePath: './installcredprovider.ps1'

  # - task: NuGetToolInstaller@1
  #   inputs:
  #     versionSpec: 5.x

  - task: NuGetCommand@2
    inputs:
      command: 'restore'
      restoreSolution: '**/*.sln'
      feedsToUse: 'config'
      nugetConfigPath: './NuGet.config'

对于上面的管道，任务setCredentialManager@0也是必须的，但是不需要运行./installcredprovider.ps1的powershell任务。

我还发现，上面的管道将无法在代理vs2017-win2016上运行，因为在执行nuget命令时会调用vs2017中的旧版本msbuild。

Paket还原、dotnet还原和nuget还原--它们都做同样的事情(dotnet还原和nuget还原将称为paket还原)。你只能把其中一个留在你的管道里。我进行了测试，我的项目是成功地与他们中的任何一个。

希望上面有帮助！
