  # Each configuration has its own variables used to customize the build - note that `pythonVersion` has moved and now varies per job
  # These jobs run in parallel (https://docs.microsoft.com/en-us/azure/devops/pipelines/process/phases?tabs=yaml&view=azure-devops#multi-configuration)

  # Steps are the specific tasks that execute code and do things

  # Use a specific Python version
  - task: UsePythonVersion@0
    displayName: Use Python $(pythonVersion)
    inputs:

  # Install some tools needed for build (pylint, flake8, etc)
  - bash: pip install -r requirements.build.txt -U --upgrade-strategy eager

  # Authenticate to Azure Artifacts

  # Install the app in editable mode to install dependencies
  - bash: pip install -e .
    displayName: Install packages for app

  # Lint via pylint. We need to find all .py files under src/simple_package and run pylint to avoid errors
  - bash: find $(srcDirectory) $(testsDirectory) -type f -name "*.py" | xargs pylint
    displayName: "Linting: pylint"

  # Lint via flake8. flake8 has better discovery, so we can invoke it directly

  # Run tests
  # Add the Python version to distinguish between tests on the results page

  # Our built source dist & wheel will land in src/simple_package/dist

    displayName: Build package
    workingDirectory: $(srcDirectory)

  # Upload everything in src/simple_package/dist (including subfolders) to the build artifacts for later use or debugging
  # Add pythonVersion to the artifact name to avoid conflicts and ensure we capture all build output
