We have recently inherited an Umbraco 8 Ucommerce project and we are in the process of setting up our build and release pipelines in Azure DevOps.

We have the following azure-pipelines.yml:

variables:
  WebsiteName: 'website'
  WebsiteAcronym: 'website'
  SolutionPath: 'src/website.sln'
  BuildConfiguration: 'Release'
  Artifact: '$(WebsiteAcronym)'
  BuildPlatform: 'x64'
  Major: '1'
  Minor: '1'
  Patch: $[counter(format('{0}.{1}', variables['Major'], variables['Minor']), 0)]
  ClientDependency.Version: '$(Major)$(Minor)$(Patch)$(Build.BuildID)'
  FrontEndDir: 'SolutionName.FrontEnd'

trigger:
    - main
name: $(WebsiteAcronym)-CI-Build-$(SourceBranchName)-$(Rev:r)
stages:
- stage: Build
  jobs:
  - job: BuildSolution

        configuration: '$(BuildConfiguration)'

    - task: VSBuild@1

        ArtifactName: $(Artifact)

The project builds and deploys to the relevant environment without any errors. Yet, a number of Ucommerce files appear to be missing from the deployment even though Ucommerce is being restored via NuGet during the build pipeline.

As Ucommerce is meant to be restored via NuGet, I'm looking to avoid including Ucommerce files within the repository.

Any ideas, please?
