透过Azure管线还原本地NuGet包问题

我在Azure Pipelines中遇到了一个问题，我有一个本地的NuGet包存在于我的repo中，我希望将它与所有其他NuGet包一起包含在pipelines构建中（这些包通常都是从nuget.org获取的）。我的项目基于ASP.NET Core构建，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repo下：MySolution/packages 正在发生的情况是，在pipelines中，nuget.org包可以恢复，但尝试查找我的本地NuGet包位置时失败，并抛出以下错误：

     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) ->

我的第一反应和大家一样...啊，路径肯定不对！然而...经过尝试各种不同的路径访问“packages”文件夹来获取本地NuGet包后，我似乎仍无法使其正常工作。

为了协助解决问题，以下是我的配置文件。

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>

我一直在尝试调整"LocalPackages"元素，但一直无法解决问题。我曾经尝试过各种路径组合来缩小范围，但都没有成功。这可能只是一个错误的线索，但也有可能是我做了什么愚蠢的事情。

我知道可以采用最佳实践，例如创建自己的NuGet软件包Artifacts feed以实现可维护性，但目前我的重点只是使流水线处于构建状态，以便进行部署和测试。

非常感谢您提供任何帮助或指导来解决这个问题。

如果需要更具体的信息，请告诉我。

谢谢。

问题出在本地软件包路径上。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，您会发现一个临时配置文件被创建，并且还要使用此临时配置文件来执行恢复任务。请参见下面的内容。

所以您在nuget.config文件中指定的本地软件包路径是相对于临时配置文件夹/home/vsts/work/1/Nuget的。

由于您的项目被克隆到文件夹/home/vsts/work/1/s（即$(system.defaultworkingdirectory)），因此您应该像下面这样指定本地软件包路径：

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