I recently updated some dependency versions in a project of mine and ran
into a clojurescript compiling problem (via lein cljsbuild):
Compiling ClojureScript...
Compiling "resources/public/js/main.js" from ["cljs"]...
Compiling "resources/public/js/main.js" failed.
clojure.lang.ExceptionInfo: failed compiling file:cljs/foo/core.cljs {:file

....
Caused by: clojure.lang.ExceptionInfo: No such namespace:

Here is the entirety (2 lines) of my clojurescript code:
(ns foo.core
(:require [taoensso.sente :as sente]))
And here's the relevant section of my project.clj:
(defproject foo "0.0.1-SNAPSHOT"
:dependencies [[org.clojure/clojure "1.8.0"]
[ring/ring-core "1.5.0"]
[com.taoensso/sente "1.10.0"]
[org.clojure/clojurescript "1.9.93"]
]
:source-paths ["clj"]
:target-path "target/%s"
:profiles {:uberjar {:aot :all}}
:plugins [[lein-cljsbuild "1.1.3"]]
...
I did a lein deps :tree and each dependency that used
org.clojure/tools.reader was using a more recent version such as 0.10.0 and
1.0.0-beta2 except for ring/ring-core which is still using 1.5.0.
RESOLUTION:
I excluded the dependency of org.clojure/tools.reader for ring/ring-core
and that took care of the compile problem.
(in project.clj:)
...
[ring/ring-core "1.5.0" :exclusions [org.clojure/tools.reader]]
...
Because I hadn't run into this problem before it cost me a few hours.
Maybe documenting this can save time for someone else.
