Azure Pipeline构建失败

Question

I have a solution that has 3 projects in it.Two of them are .Net Standard project and one is a .Net Framework project which is Unit Test. I am trying to build it but I get an error.

 C:\Program 
 Files\dotnet\sdk\2.2.105\Sdks\Microsoft.NET.Sdk\targets\Microsoft.PackageDependencyResolution.targets(208,5): Error NETSDK1004: Assets file 'D:\a\1\s\src\TestIOC\obj\project.assets.json' not found. Run a NuGet package restore to generate this file.
C:\Program Files\dotnet\sdk\2.2.105\Sdks\Microsoft.NET.Sdk\targets\Microsoft.PackageDependencyResolution.targets(208,5): Error NETSDK1004: Assets file 'D:\a\1\s\src\TestMvvm\obj\project.assets.json' not found. Run a NuGet package restore to generate this file.
Process 'msbuild.exe' exited with code '1'.

This is my current Azure Pipelines YAML file.

trigger:
- master

pr:
- master

variables:
  buildConfiguration: Release
  buildPlatform: Any CPU
  coreSolution: 'src\TestMvvmCore.sln'
  coreCSProj: 'src\TestMvvm\*.csproj'
  testCSProj: 'src\TestMvvm.Tests\*.csproj'
pool:
    vmImage: vs2017-win2016

steps:

- task: NuGetToolInstaller@1
  inputs:
    versionSpec: '4.9.1'

- task: NuGetCommand@2
  inputs:
    command: 'restore'
    restoreSolution: '**/*.sln, src\TestMvvm.Tests\packages.config'
    feedsToUse: 'select'

- task: MSBuild@1
  displayName: Build TestMvvm Solution
  inputs:
    solution: '$(coreSolution)'
    configuration: '$(buildConfiguration)'
    restoreNugetPackages: true

I would appreciate if someone can help me fix the error

Answer 1

Since your project type and msbuild task would not call dotnet restore automatically, it need execute another task to call it explicitly. You can try with execute dotnet restore task instead of nuget restore before execute msbuild xxx.sln .

In addition, you can also add /t:restore into MSBuild Argument to call dotnet restore explicitly:

msbuildArguments: ‘/t:restore’

Note: In msbuild task, restoreNugetPackages has been deprecated now. It will not work any more and you must use task to achieve restore package.

Answer 2

You have to restore your nuget package first, and you have to supply with SLN file, not with the packages.config.

Your NugetCommand@2 task should only restore a solution file, not restoring packages.config file. Correct your YAML first.
