aws-codepipeline-actions: Problem Cloning the AWS CDK Repository on Windows

[azarboon]

Describe the bug

When cloning the AWS CDK repository on a Windows system, I encountered issues where certain files appear in the Git index but are not present on the filesystem. This causes git status to show these files as deleted, and attempts to restore or interact with them fail. The issue might be related to Windows' filesystem limitations, but the root cause remains unclear.

To fix the issue, I cloned the repository using Windows Subsystem for Linux (WSL) in VS Code, the Bash terminal in VS Code, and Git Desktop's Bash, but none of these helped. I also changed case sensitivity (through core.ignorecase), enabled long file paths (through core.longpaths), and modified the Windows registry, but this did not resolve the problem.

Expected Behavior

The repository should clone successfully on Windows, with all files checked out to the filesystem as expected. Running git status and git diff after merging updates from upstream/main should not show any unexpected deletions or errors related to file handling. Cross-platform compatibility issues, if present, should be handled gracefully to allow contributors to work seamlessly regardless of their operating system.

Current Behavior

git status
On branch main
Your branch is up to date with 'origin/main'.

Reproduction Steps

# Fork the AWS CDK repository on GitHub
# Clone the forked repository
git clone https://github.com/<your-username>/aws-cdk.git
cd aws-cdk

# Add the upstream repository to fetch updates
git remote add upstream https://github.com/aws/aws-cdk.git

# Fetch the latest changes from upstream and merge them
git fetch upstream
git merge upstream/main

# Check the status to see any changes
git status

# View differences in the repository
git diff

# Attempt to restore problematic files
git restore <file>

Possible Solution

1. Investigate and address why the files cannot be created on Windows systems.
2. Consider renaming files with incompatible characters (e.g., replacing colons with _ or -).
3. Provide a script or process to handle these files for Windows users specifically.
