Hey Josh,

I was having the same problem. I noticed adding (:gen-class) to the ns of all my components fixed the problem. Cant explain why though I'm affraid.

(ns components.web-server
(:require [com.stuartsierra.component :as component]
[aleph.http :refer [start-http-server wrap-ring-handler]]
[taoensso.timbre :as timbre :refer [info]]
[app.handler :refer [app]])
(:gen-class))

I was having the same problem. What fixed it for me was making sure the :uberjar map had these two map-entries:

{
:main my.server-main
:aot [my.server-main com.stuartsierra.component com.stuartsierra.dependency]
}

Previously :aot :all was there, but inspection of the created jar file made me realize it wasn't working: there were barely any .class files there, certainly not com/stuartsierra/component/Lifecycle.

(I also tried the other suggestion, putting (:gen-class) where there were components, but that didn't help)
