Thank you for working on this and submitting this pull request. We want this so we can use s3 as a source instead of GitHub. However, when testing your changes, s3 as a source fails with the following error: "Source version should be empty for S3 folder source location". The sourceVersion also needs to be left unset in order to get s3 to work as a source.

May I ask why this is not merged ? I need this feature very much in my project

Is it going to be merged? I just want GitHub actions to trigger CodeBuild to run build commands in VPC. It doesn't need a source of GITHUB

@smailc I actually forked and tweaked it to do this https://github.com/mostmentor/aws-codebuild-run-build
