How can I resolve the "The mount '/example' has a path that overlaps with a non-empty folder" build error message?

If you get a message like the following:

W: The mount '/example' has a path that overlaps with a non-empty folder.
The content of the non-empty folder either comes from:
- your git repository (you may have accidentally committed files).
- or from the build hook.
Please be aware that this content isn't accessible at runtime.

That means that:

• There's a mount with the same name as a directory committed to Git.
• A directory was created during build whose name conflicts with an already existing one.

To resolve this issue, follow the steps outlined in the overlapping folders section, here:
