Java.lang.IllegalArgumentException: no implementation of method :: route-matches protocol: # 'clout.core / Route

Question

I have two files of interest: build.boot

(set-env! :source-paths #{"src/clj" "src/cljs" "test/clj"} :resource-paths #{"html" "target/main.js"} :dependencies '[[adzerk/boot-cljs "0.0-3308-0"] [adzerk/boot-cljs-repl "0.1.10-SNAPSHOT"] [adzerk/boot-reload "0.3.1"] [adzerk/boot-test "1.0.4"] [cljsjs/hammer "2.0.4-4"] [compojure "1.3.1"] [com.datomic/datomic-pro "0.9.5186"] [hiccup "1.0.5"] [org.clojure/clojure "1.7.0-RC1"] [org.clojure/clojurescript "0.0-3308"] [org.clojure/core.async "0.1.346.0-17112a-alpha"] [org.clojure/test.check "0.7.0"] [org.omcljs/om "0.8.8"] [pandeiro/boot-http "0.6.3-SNAPSHOT"] [ring/ring-devel "1.4.0-RC1"] [http-kit "2.1.18"]]) (require '[adzerk.boot-cljs :refer [cljs]] '[adzerk.boot-cljs-repl :refer [cljs-repl start-repl]] '[adzerk.boot-reload :refer [reload]] '[adzerk.boot-test :refer [test]] '[pandeiro.boot-http :refer [serve]]) (task-options! cljs {:source-map true :optimizations :none :pretty-print true}) (deftask build "Build an uberjar of this project that can be run with java -jar" [] (comp (cljs) (aot :namespace '#{vidiot.server}) (pom :project 'vidiot :version "0.1.0") (uber) (jar :main 'vidiot.server))) 

and src / clj / vidiot / server.clj

 (ns vidiot.server (:gen-class) (:require [compojure.core :refer :all] [compojure.route :as route] [hiccup.core :refer :all] [org.httpkit.server :refer :all] [ring.middleware.reload :as reload] [ring.util.response :as response])) (defonce server (atom nil)) (defroutes all-routes (GET "/" [] (response/redirect "index.html")) (GET "/ws" [request] (with-channel request channel (on-close channel (fn [status] (println "channel closed: " status))) (on-receive channel (fn [data] ;; echo it back (send! channel data))))) (route/files "/" {:root "target"}) (route/not-found (response/response (html [:div#erro "Page Not Found"])))) (defn -main [& args] (run-server all-routes {:port 8080})) 

Then I,

  > boot build > java -jar target/vidiot-0.1.0.jar 

Then, going to localhost: 9090 in my browser, the terminal prints.

 java.lang.IllegalArgumentException: No implementation of method: :route-matches of protocol: #'clout.core/Route found for class: clout.core.CompiledRoute at clojure.core$_cache_protocol_fn.invoke(core_deftype.clj:554) at clout.core$eval5590$fn__5591$G__5581__5598.invoke(core.clj:39) at compojure.core$if_route$fn__5887.invoke(core.clj:40) at compojure.core$if_method$fn__5879.invoke(core.clj:27) at compojure.core$routing$fn__5918.invoke(core.clj:127) at clojure.core$some.invoke(core.clj:2568) at compojure.core$routing.doInvoke(core.clj:127) at clojure.lang.RestFn.applyTo(RestFn.java:139) at clojure.core$apply.invoke(core.clj:630) at compojure.core$routes$fn__5922.invoke(core.clj:132) at org.httpkit.server.HttpHandler.run(RingHandler.java:91) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745) 

I can fix this problem by lowering : dependencies in build.boot to [compojure "1.1.6"] .

So my question is: why can't I use [compojure "1.3.4"] (the latest version when writing) when creating my uberjar?

Answer 1

Placing the aot task after uber fixes the problem.

 (task-options! pom {:project 'my-project :version "0.1.0"} jar {:main 'my-project.core} aot {:namespace '#{my-project.core}}) (deftask build [] (comp (pom) (uber) (aot) (jar))) 

Answer 2

I was able to fix this by adding an exception to the clout folder. It seems that uberjar is unpacking some compiled clout files on top of those compiled from the project source. An example from my project:

  (comp (cljs :compiler-options {:output-to "js/main.js"}) (aot :namespace '#{zoondka-maps.server zoondka-maps.handler}) (pom :project (symbol (:name project)) :version (:version project)) (uber :exclude (conj pod/standard-jar-exclusions #".*\.html" #"clout/.*")) (jar :file (str (:name project) ".jar") :main 'zoondka-maps.server)))
