通过 Azure Pipelines 还原本地 NuGet 包的问题

Question

我在 Azure Pipelines 中遇到了一个问题，我的存储库中有一个本地 NuGet 包，我希望将它包含在与所有其他 NuGet 包一起构建的管道中（通常都是从 nuget.org 获取的）。我的项目是基于 ASP.NET Core 构建的，更具体地说，它是一个 Blazor 服务器端 Web 应用程序。

本地 NuGet 包“Breeze.Sharp.0.9.6.nupkg”存储在我的仓库中：MySolution/packages

发生的情况是 nuget.org 包在管道中恢复正常，但是当它尝试查找我的本地 NuGet 包位置并引发以下错误时失败：

     1>/usr/share/dotnet/sdk/3.1.402/NuGet.targets(128,5): error : The local source '/home/vsts/work/1/Nuget/MySolution/packages' doesn't exist. [/home/vsts/work/1/s/MySolution/MySolution.sln]

Build FAILED.

       "/home/vsts/work/1/s/MySolution/MySolution.sln" (Restore target) (1) ->
       (Restore target) -> 

我的第一想法和其他人一样...... 啊路径一定是错误的！但是...在尝试各种不同的路径以获取包文件夹以获取我的本地 NuGet 包后，我似乎无法使其工作。

为了提供帮助，我的配置文件如下。

azure-pipelines.yml：

trigger:
- master

pool:
  vmImage: 'ubuntu-latest'

variables:
  buildConfiguration: 'Release'

steps:   
- task: NuGetToolInstaller@1
  displayName: 'Use NuGet 4.9.1'
  inputs:
    versionSpec: 4.9.1

- task: DotNetCoreCLI@2
  displayName: 'Restore NuGet Packages'
  inputs:
    command: 'restore'
    projects: '**/*.sln'
    feedsToUse: 'config'
    nugetConfigPath: 'MySolution/NuGet.Config'

- task: DotNetCoreCLI@2
  displayName: 'Build web project'
  inputs:
    command: 'build'
    projects: $(SolutionPath)
    

NuGet.Config：

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <packageSources>
        <clear />
        <add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />
        <add key="LocalPackages" value="MySolution/packages" />
    </packageSources>
</configuration>

我一直在搞砸的部分是“LocalPackages”元素，我认为这可能是问题所在，因此一直在尝试各种路径组合来尝试缩小范围 - 但没有运气 -这让我觉得这可能是一个红鲱鱼，但你永远不知道我可能会做一些愚蠢的事情！

我知道这里可以遵循一些最佳实践，例如创建我自己的 NuGet 包的 Artifacts 提要以实现可维护性，但这对我来说将是稍后的改进阶段，我目前的重点只是简单地获取管道处于准备好部署和测试的构建状态。

任何有关此问题的帮助或指导或我可以尝试解决此问题的事情将不胜感激！

如果需要更具体的信息，请告诉我，我可以提供！

谢谢。

这是导致问题的本地包路径。您应该将值设置为<add key="LocalPackages" value="../s/MySolution/packages" />

如果您检查 dotnet restore 任务日志，您会发现创建了一个临时配置，并且还原任务正在使用此临时配置文件。见下文。

因此，您在 nuget.config 文件中指定的 LocalPackages 路径是相对于临时配置文件夹 /home/vsts/work/1/Nuget。

由于您的项目被克隆到文件夹/home/vsts/work/1/s（即$(system.defaultworkingdirectory)）中。您应该指定 LocalPackages 路径，如下所示：

<add key="LocalPackages" value="../s/MySolution/packages" />
