Overview of the Issue

I noticed that when migrating files into a subdirectory such as parent/*.tf to parent/subdir/*tf, it will try to plan the empty parent/ dir even though there aren’t any matching *.tf files and fail to plan. Anyone know of a configuration fix for this or is this a bug?

To get around this, I’m thinking of updating the workflow to check if the directory is empty before the init workflow and if it is, just do an early exit 0

This issue makes refactoring more difficult.

Reproduction Steps

1. Find a directory of terraform files e.g. parent/*.tf
2. Create a new directory within that directory parent/subdir
3. Move the contents of parent/*.tf to parent/subdir
4. Create a PR

Atlantis will try to plan both parent/ and parent/subdir. The latter will succeed and the former will fail because there are no terraform files here.

Environment details

Additional Context

• Must be a bug in auto discovery. The directory shouldn't even show up if there aren't any terraform files in there. See docs: auto discovering of projects #3038

We have also hit this issue. We tried to work around it by creating a new folder in a separate PR and applying that first, then creating a 2nd PR that deletes the old directory, but the problem persists with the deletion of the existing directory. We have the ability to emergency merge a PR into the protected main branch, but only if the checks all pass and so Atlantis itself is blocking the emergency merge.
