Hi, I wrote a question some time ago on stack overflow regarding functionality that I'm looking for: https://stackoverflow.com/questions/64215749/logback-is-there-a-way-to-inclu... Unfortunately I only got one comment and it seems that functionality is not there. Is there any way to achieve what I want to do? I hasten to add that our application is a spring-boot based application (based on Tomcat) and we really don't know anything about modules that people write for it - but we know that some people do. I'm pasting my question from SO below: Is there a way to do something along the lines: <configuration> <include file="src/main/java/chapters/configuration/*.xml" /> <!-- some common stuff --> </configuration> Note *.xml in <include> tag. I have an application consisting of 9 modules, but not all of them are always present. In addition there are external modules that can be installed optionally and I don't know their names in advance (by names I mean class names or config names) or how they should be configured. If there was a way to include files using wildcard I could simply notify developers that they should place their config files in some directory (e.g. config/logging/) and I'd be set for life. Currently files must be included by hand. Of course I could write some code that monitors given file for new configurations and include them programmatically in main configuration file (or proper <include> tags), but maybe there is already a way to do it. -- Jędrzej Dudkiewicz I really hate this damn machine, I wish that they would sell it. It never does just what I want, but only what I tell it.
