If you don't have Windows Directory Sharing correctly done, you get the WORST error message

[r2-lf]

This is Docker's fault. But, if you don't have Docker Desktop configured to read the src\test\resources\docker directory on Windows, you get the message at the bottom.

Docker Desktop --> Settings --> Resources --> File Sharing --> add that directory.

We should be really explict about this for our friends (like me!) that use Windows Docker Desktop.
