See https://github.com/spring-cloud/spring-cloud-config/issues/2051 for background.
Currently when a config import fails the processing is aborted. This means that logging configuration is ignored, even if it's in a part of the config data that loaded OK. It might be nice if we could fail after the logging system has been initialized so that logging is available.

Hello @philwebb I tried to play with the issue and I don't have any answer for it. I was thinking to use logback.xml to create log file with wide variety of configurations? I'm pretty new to this, I was just trying to help you.
