The
update-cgmanifest.ps1
script was regenerating the entirecgmanifest.json
file each time it ran, causing unnecessary changes in source control even when there were no actual changes to package versions.Issues Fixed
Changes Made
Sort-Object { $_.component.nuget.name }
to ensure consistent package orderingNew-PackageEntry
function to use[ordered]
hashtables for consistent JSON property orderingBefore/After Comparison
Before: Running the script twice would show git changes even with identical package versions:
After: Running the script multiple times produces identical output with no spurious git changes, and shows "No changes detected - cgmanifest.json is already up to date" when appropriate.
Testing
✅ Script produces identical output on successive runs
✅ Packages are sorted alphabetically by name
✅ JSON properties have consistent ordering (
type
→nuget
→name
→version
)✅ Content comparison optimization works correctly
✅ Cake build integration (
dotnet cake --target=GenerateCgManifest
) still works✅ New file creation functionality preserved
✅ All existing functionality maintained
Fixes #30054.
