When i try to run lambda local using intellij IDE. Sam started to build project from temp location where it copies the files and folder from source (using codeUri) to temp location and parsing all the files then start to executing invoke command. After that build get failed and showing permission denied error.

Additional context
My project contains source control files (.git files). SAM build failed because it not able read git objects. If there any way to SKIP the folder while build.

Hi,

This is a critical issue. Running a compilation in Docker is slow and not all our customers can run Docker on their Windows laptops/workstations because of organizations security policies.

Do you have any updates when it is planned to be resolved?

Thanks in advance!

It looks like this issue exists only when function code in the root folder. If you move the function code into the subfolder, everything is working as expected.

I submitted a PR to ignore .git folder, looks like Python already had this but Java (maven specifically, I did not look at gradle) only has .aws-sam as the ignore directory. Suggested by @TheSrira #1241

This is merged. Closing the issue.
