Ignore hidden files when running sam build

[zhangzhx]

Describe your idea/feature/enhancement

When running sam build for python, sam copies the whole folder structure of the lambda base directory to the target build folder. I wish SAM CLI would ignore all the hidden files that is not needed for building the project, or at least provide a parameter to specify what folder/files should be ignored.

Yeah each workflow in aws-lambda-builders has a series of files they excluded, but its locked into the workflow directly.

I'll mark this issue as a feature request.

This has been merged into lambda builders. Closing.
