Below is the order in which c.t.l picks up loggers: 1. SLF4j (which also includes Logback, since it natively implements the SLF4j API) 2. Apache Commons-logging 3. Log4j 4. java.util.logging
Reference: https://github.com/clojure/tools.logging/blob/master/src/main/clojure/clojure/tools/logging/impl.clj#L214 Both #1 and #2 are merely logger facade, incapable of logging anywhere except to the console by themselves. They need an underlying logger for real-world logging. Your dependencies only include the SLF4j-log4j bridge (without the log4j dependency), which I am not sure is supposed to be picked up by c.t.l. I would suggest either remove slf4j-log4j dependency altogether (allowing j.u.l to be chosen) or add the slf4j [org.slf4j/slf4j-api "1.7.13"] and log4j [log4j/log4j "1.2.17"] dependencies to your current config. Hope this helps.
