It is unclear from the documentation that the
spring.config.location
andspring.config.additional-location
properties are mutually exclusive. This change explicitly documents it.The wording is subject to change, but I think the fact that these properties are mutually exclusive should be documented explicitly.
It took me about a day (before eventually delving into the spring code in
ConfigFileApplicationListener
) to realize I could not use these in tandem, I would like to avoid others having to make the same mistake.
