I have 2 Spring Boot (1.4.1-RELEASE) console applications using Logback. Both configuration files are more or less identical, are located in my /src/main/resources
I would specify in application.properties the location of the config file like that.
logging.config=path
Spring might not be looking for this file name. Spring doc
They suggest using this name logback-spring.xml rather than just logback.xml
I would place the configuration in application.properties if possible.
