Allow to not found source files option

[Tacha-S]

If we try to set up GitHub CI when we create a repository, then no source file exists. In that case, the GitHub CI will be an error, so we want an option to allow the source file to not exist.

I would like this feature as well.

As a workaround, I just added a step to the job that checks if the directory exists or not.
