Azure devops Cant为Nuget程序包连接Nuget Restore和VSBuild

到目前为止，我有一个非常基本的构建管道

# ASP.NET
# Build and test ASP.NET projects.
# Add steps that publish symbols, save build artifacts, deploy, and more:
# https://docs.microsoft.com/azure/devops/pipelines/apps/aspnet/build-aspnet-4

trigger:
- testing-build-yml-1

pool:
  vmImage: 'windows-latest'

variables:
  solution: '**/*.sln'
  buildPlatform: 'Any CPU'
  buildConfiguration: 'Release'

steps:
- task: NuGetToolInstaller@1

- task: NuGetCommand@2
  inputs:
    restoreSolution: '$(solution)'
    # packagesDirectory: '..\packages'
    restoreDirectory: '..\new_packages'

- task: VSBuild@1
  inputs:
    solution: '$(solution)'
    #msbuildArgs: '/p:DeployOnBuild=true /p:WebPublishMethod=Package /p:PackageAsSingleFile=true /p:SkipInvalidConfigurations=true /p:PackageLocation="$(build.artifactStagingDirectory)"'
    msbuildArgs: '/p:DeployOnBuild=true /p:WebPublishMethod=Package /p:PackageAsSingleFile=true /p:SkipInvalidConfigurations=true /p:PackageLocation="$(build.artifactStagingDirectory)" /p:ReferencePath="d:\a\1\new_packages"'
    platform: '$(buildPlatform)'
    configuration: '$(buildConfiguration)'

我正在尝试执行Nuget Restore任务，以将软件包还原到..\new_packages目录，然后希望VSBuild Task从那里获取它们并构建解决方案。

Nuget Restore执行以下命令（全部一行）

C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\MSBuild\Current\bin\msbuild.exe 
  "C:\Users\VssAdministrator\AppData\Local\Temp\NuGetScratch\jgtjjpe0.nac.nugetinputs.targets" 
  /t:GenerateRestoreGraphFile 
   /nologo 
   /nr:false 
   /v:q 
  /p:NuGetRestoreTargets="C:\Users\VssAdministrator\AppData\Local\Temp\NuGetScratch\whba0xm4.c0f.nugetrestore.targets" 
  /p:RestoreUseCustomAfterTargets="True" /p:RestoreTaskAssemblyFile="C:\hostedtoolcache\windows\NuGet\5.4.0\x64\nuget.exe" 
  /p:RestoreSolutionDirectory="D:\a\1\s\\" 
  /p:RestoreConfigFile="D:\a\1\Nuget\tempNuGet_105.config" 
  /p:RestorePackagesPath="..\new_packages" 
  /p:SolutionDir="D:\a\1\s\\" 
  /p:SolutionName="XYZ"

然后，VSBuild Task运行msbuild（全部一行）

##[command]"C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\MSBuild\Current\Bin\msbuild.exe" 
 "D:\a\1\s\XYZ.sln" 
   /nologo 
   /nr:false 
   /dl:CentralLogger,
 "D:\a\_tasks\VSBuild_71a9a2d3-a98a-4caa-96ab-affca411ecda\1.161.2\ps_modules\MSBuildHelpers\Microsoft.TeamFoundation.DistributedTask.MSBuild.Logger.dll";
 "RootDetailId=e5869970-8e7b-4a06-a8fd-f0662f639a6d|SolutionDir=D:\a\1\s"*ForwardingLogger,"D:\a\_tasks\VSBuild_71a9a2d3-a98a-4caa-96ab-affca411ecda\1.161.2\ps_modules\MSBuildHelpers\Microsoft.TeamFoundation.DistributedTask.MSBuild.Logger.dll"
 /p:DeployOnBuild=true 
 /p:WebPublishMethod=Package 
 /p:PackageAsSingleFile=true 
 /p:SkipInvalidConfigurations=true 
 /p:PackageLocation="D:\a\1\a" 
 /p:ReferencePath="d:\a\1\new_packages" 
 /p:platform="Any CPU" 
 /p:configuration="Release" 
 /p:VisualStudioVersion="16.0" 
 /p:_MSDeployUserAgent="VSTS_607486bc-2d64-463d-9a7f-0cf06fe82263_build_16_0"

解决方案将根据中指定的适当目录进行查找/p:ReferencePath="d:\a\1\new_packages。

但是它仍然找不到Nuget软件包的任何dll，最终构建失败。

从技术上讲，我知道我们不应该/p:ReferencePath=..对此进行硬编码，而只是在尝试使其工作。

没有那个，VSBuild Task似乎根本不知道在哪里看。

它看着

使用管道的旧方法也有类似的问题

MsBuild在Visual Studio Online上找不到还原的NuGet软件包

他们的解决方案（尽管很笨拙）对我也不起作用。

如果我删除EPPlus软件包，则下一个软件包Entity Framework将产生相同的错误。
如果删除Entity Framework下一个包，将产生相同的错误。

我只是想为此找到一个真正的解决方案，它不涉及这些硬编码黑客（显然，..和有效）

努力工作，非常感谢Leo Liu-MSFT。
