Gradle distZip config files

I have an application installed via distZip (gradle application plugin). It has the bin and lib folders. Now where do I place the config files? Like logback.xml or application.properties, etc? Or do I need to somehow tell the plugin where are the files?

Put your configuration files(logback.xml/application.properties) into src/main/resources(sourceSets.main.resources), then they will be included into jar.
