FileAlreadyExistsException prints stack trace but VS Code does not flag compilation as failed

The following was printed:

Yet, VS Code reported a successful compilation.

This was marked as invalid. Does that mean that the report is invalid? In that case, we should close this issue.

Oops, I didn't know that that was what that meant. To my knowledge this issue should still be open.
