I'm seeing this problem in my builds more or less randomly, and don't seem to be the only one
http://stackoverflow.com/questions/8291910/noclassdeffounderror-with-clojure-tools-logging https://groups.google.com/forum/#!msg/datomic/6xWGFB-Dx68/_Hr2I4lv39gJ http://clojure-log.n01se.net/date/2012-10-16.html Second link seems to think it's a problem with datomic or maybe lein, but I'm using maven and not using datomic, so it *seems* like there's some race condition involving loading logging classes where this happens. I don't understand this, since LoggerFactory is defined at top-level in clojure.tools.logging.impl and impl is required in the ns declaration of clojure.tools.logging. -- -- You received this message because you are subscribed to the Google Groups "Clojure" group.
