Devops Build Pipeline - Error MSB3073: The command XCOPY

Question

I have solution contains multi projects, and I'm trying to build Azure devops pipeline on single project (.csproj), when build I have this error.

##[error]C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\MSBuild\Current\Bin\Microsoft.Common.CurrentVersion.targets(5574,5): Error MSB3073: The command "XCOPY /Y D:\a\1\s\XXX\XXX\bin\Release\XXX.dll UndefinedNuget\lib\net40" exited with code 4.

and this is my azure-pipelines.yml file

trigger:
- Sprint47

pool:
  vmImage: 'windows-latest'
  
variables:
  solution: '**/*.sln'
  buildPlatform: 'AnyCPU'
  buildConfiguration: 'Release'

steps:

- task: VSBuild@1
  inputs:
    solution: 'XXX\XXX\XXX.csproj'
    msbuildArgs: '/p:Configuration=Release /p:Platform=AnyCPU /p:DeployOnBuild=true /p:WebPublishMethod=Package /p:PackageAsSingleFile=true /p:SkipInvalidConfigurations=true /p:PackageLocation="$(build.artifactStagingDirectory)"'
    platform: 'AnyCPU'
    configuration: 'Release'

- task: VSTest@2
  inputs:
    platform: '$(buildPlatform)'
    configuration: '$(buildConfiguration)'

- task: PublishBuildArtifacts@1

How I can solve this problem.

First, you should add the nuget restore task to restore the necessary nuget packages to make sure that the required dlls are copied into bin folder.

Like this:

steps:
- task: NuGetToolInstaller@1   
  inputs:
    versionSpec: 5.x
    
- task: NuGetCommand@2
  inputs:
    restoreSolution: '$(solution)'

- task: VSBuild@1
   inputs:
    solution: 'XXX\XXX\XXX.csproj'
    msbuildArgs: '/p:Configuration=Release /p:Platform=AnyCPU /p:DeployOnBuild=true /p:WebPublishMethod=Package /p:PackageAsSingleFile=true /p:SkipInvalidConfigurations=true /p:PackageLocation="$(build.artifactStagingDirectory)"'
    platform: 'AnyCPU'
    configuration: 'Release'

Besides, you should check the command XCOPY /Y .... under the csproj file. Make sure the xcopy /Y file1 path1 is legal.

I noticed UndefinedNuget\lib\net40 and you should check whether the property is parsed correctly. Use a right property or path.

Also, please add /R additionally to run the command.

Like this:

XCOPY /Y /E /R file1 path1

Do not forget to share the XCOPY command with us to troubleshoot the issue if these above do not help.
