[Codegen] Hidden folder detection skips all files when workspace path contains hidden directory (e.g. ~/.jenkins/) #55243
Description
Description
Summary
The codegen's findFilesWithExtension() function incorrectly skips all .mm files when the project workspace is located under a hidden directory (e.g., ~/.jenkins/, ~/.buildkite/, ~/.circleci/). This causes third-party Fabric components to not be registered in RCTThirdPartyComponentsProvider.mm.
Affected Versions
- React Native 0.79.x (confirmed)
- React Native 0.81.x (confirmed - code moved to
generateRCTThirdPartyComponents.js)
Root Cause
In generate-artifacts-executor.js, the hidden folder check uses:
if (absolutePath.includes(`${path.sep}.`) && !absolutePath.includes(`${path.sep}.pnpm`)) {
return null;
}This checks if /. appears anywhere in the entire path, not just the current filename. When the workspace is under ~/.jenkins/workspace/..., every file path contains /.jenkins, triggering the exclusion.
Suggested Fix
Change the check to examine only the current file/folder name:
if (file.startsWith('.') && file !== '.pnpm') {
return null;
}This correctly skips hidden folders like .git while allowing files under workspace paths like ~/.jenkins/.
Steps to reproduce
- Set up a React Native project with New Architecture enabled
- Add a third-party Fabric component (e.g.,
@shopify/flash-list) - Build from a workspace under a hidden directory (e.g.,
~/.jenkins/workspace/project/) - Run
pod installand check the generatedRCTThirdPartyComponentsProvider.mm
Expected: File contains component mappings (e.g., AutoLayoutView, CellContainer)
Actual: File contains no third-party component mappings

N/A (it's a build issue and using the template will use Github Actions and will not reproduce the issue - it happen only on CI tools with their default installation path at ~/.jenkins or ~/.buildkite or ~/.circleci)
