Including .clj file in ClojureScript project

I'm building a Node.js app in ClojureScript and testing out macros.

Directory structure:

├── project.clj
└── src
    └── lists
        ├── core.cljs
        └── lib.clj

project.clj:

(defproject lists "0.1.0-SNAPSHOT"
  :source-paths ["src/"]
  :dependencies [[org.clojure/clojure "1.7.0"]]
  :plugins [[lein-cljsbuild "1.1.2"]]
  :cljsbuild {:builds
              [{:source-paths ["src"]
                :compiler {:output-to "target/lists.js"
                          :optimizations :simple
                          :target :nodejs}}]})

src/lists/core.cljs:

(ns lists.core
  (:require [lists.lib :as lib :include-macros true]))

(enable-console-print!)

(lib/defmain [& args]
  (console.log "hello world"))

src/lists/lib.clj:

(ns lists.lib)

(defmacro defmain [& body]
  `(set! *main-cli-fn* (fn ~@body)))

When I run lein cljsbuild once, I get a huge error traceback containing:

Caused by: clojure.lang.ExceptionInfo: No such namespace: lists.lib, could not locate lists/lib.cljs or lists/lib.cljc at line 1 src/lists/core.cljs {:file "src/lists/core.cljs", :line 1, :column 1, :tag :cljs/analysis-error}

The folder structure is right, and :source-paths is present in both the outer defproject call and inner :cljsbuild :builds object. What's even weirder is that sometimes it exits without printing anything. Anyone have any ideas?

cljsbuild is throwing an exception because it doesn't understand .clj files, it's looking for .cljs or .cljc files in the "src" directory. You have to rename lib.clj to lib.cljc check using cljc on the clojurescript wiki.
