Aditional info

When running DotNetCoreCLI@2 for "restore" multiple times, the nuget.config path is ignored the second time.

E.g.


...
- task: UseDotNet@2
  displayName: Use .NET 6 SDK
  inputs:
    packageType: sdk
    version: 6.x

- task: NuGetToolInstaller@1
  displayName: 'Use NuGet 6.2'
  inputs:
    versionSpec: 6.2.*

- task: NuGetAuthenticate@1

- task: DotNetCoreCLI@2
  displayName: 'NuGet restore Some Solution'
  inputs:
    command: 'restore'
    projects: '$(Build.SourcesDirectory)\build\elastic_log.sln'
    feedsToUse: 'config'
    nugetConfigPath: '$(Build.SourcesDirectory)/MyPath1/nuget.config'
    noCache: true

- task: CmdLine@2
  displayName: 'DEBUG SHOW NUGET CONFIG'
  inputs:
    script: 'type $(Pipeline.Workspace)\Nuget\tempNuGet_$(Build.BuildID).config'
  condition: always()

- task: DotNetCoreCLI@2
  displayName: 'NuGet restore Other Solution'
  inputs:
    command: 'restore'
    projects: '$(Build.SourcesDirectory)\build\test.sln'
    feedsToUse: 'config'
    nugetConfigPath: '$(Build.SourcesDirectory)/MyPath2/nuget.config'
    noCache: true

- task: CmdLine@2
  displayName: 'DEBUG SHOW NUGET CONFIG 2'
  inputs:
    script: 'type $(Pipeline.Workspace)\Nuget\tempNuGet_$(Build.BuildID).config'
  condition: always()


Example $(Build.SourcesDirectory)/MyPath1/nuget.config

```xml
<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <packageSources>
        <clear />
        <add key="MSAzure" value="https://msazure.pkgs.visualstudio.com/One/_packaging/MY-FEED/nuget/v3/index.json" />
    </packageSources>
</configuration>

Example $(Build.SourcesDirectory)/MyPath2/nuget.config

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <packageSources>
        <clear />
        <add key="LocalFeed" value="%BUILD_BINARIESDIRECTORY%\RelWithDebInfo\test_nuget" />
        <add key="MSAzure" value="https://msazure.pkgs.visualstudio.com/One/_packaging/MY-FEED2/nuget/v3/index.json" />
    </packageSources>
</configuration>

Expected:

Each invocation of NuGet restore will use the provided nuget.config.

Actual, the first time it is executed a file is created at $(Pipeline.Workspace)\Nuget\tempNuGet_$(Build.BuildID).config with the provided config (and then auth keys are added). The second time, the file exists so the nuget.config from nugetConfigPath is ignored (silently).

I looked at the source here and it seems to be due to the behavior of ensureTempConfigCreated() which uses the existing file even if there is a different config provided

azure-pipelines-tasks/Tasks/Common/packaging-common/nuget/NuGetConfigHelper2.ts

Line 44 in 4db1906

public ensureTempConfigCreated() {

I am also experiencing this issue.

This issue does still affect us, and we currently have a hacky work-around to delete $(Pipeline.Workspace)\Nuget\*.config files.
