运行Midje测试时的FileNotFound异常

Question

我有一个Leiningen项目，它使用Midje库进行测试。但是，我不能运行任何测试，如果我得到lein test

java.io.FileNotFoundException: Could not locate midje/sweet__init.class or midje/sweet.clj on classpath

或者用lein midje test我得到

java.io.FileNotFoundException: Could not locate midje/util/ecosystem__init.class or midje/util/ecosystem.clj on classpath

因此，我想这是因为我错误地定义了带有依赖项的dev配置文件，但我不知道真正的问题在哪里。

另外，我也不能让environ工作，我总是得到nil，我想从env映射中提取一些属性(这可能也是同样的问题)。

我的project.clj

(defproject
  project
  "0.1.0-SNAPSHOT"
  :dependencies
   [[org.clojure/clojure "1.8.0"]
   [environ "1.1.0"]
   ;; other deps, midje is not there
   :repl-options
      {:init-ns mailing.repl}
   :jvm-opts
      ["-server"]
   :plugins
      [[lein-ring "0.8.13"]
       [lein-environ "1.0.0"]
       [lein-ancient "0.5.5"]
       [migratus-lein "0.4.2"]]

我没有试过这个，但是这个结构看上去不太正确。我觉得应该是这样的：

(defproject project "0.1.0-SNAPSHOT"
  :dependencies [[org.clojure/clojure "1.8.0"]
                 [environ "1.1.0"]]
  ;; other deps, midje is not there
  :repl-options {:init-ns mailing.repl}
  :jvm-opts ["-server"]
  :plugins [[lein-ring "0.8.13"]
            [lein-environ "1.0.0"]
            [lein-ancient "0.5.5"]
            [migratus-lein "0.4.2"]]
  :ring {:handler mailing.handler/app
         :init mailing.handler/init
         :destroy mailing.handler/destroy}
  :profiles {:uberjar {:omit-source true
                       :env {:production true}
                       :aot :all}
             :production {:ring {:open-browser? false
                                 :stacktraces? false
                                 :auto-reload? false}}
             :dev {:env {:db-user "user"
                         :db-password "psswd"
                         :db-classname "org.postgresql.Driver"
                         :db-subprotocol "postgresql"
                         :db-subname "//localhost/mailer"
                         :dev true}
                   :dependencies [[ring-mock "0.1.5"]
                                  [ring/ring-devel "1.3.1"]
                                  [midje "1.6.3"]]}}
  :migratus {:store :database
             :migration-dir "migrations"
             :db {:classname "org.postgresql.Driver"
                  :subprotocol "postgresql"
                  :subname "//localhost/mailer"
                  :user "usr"
                  :password "psswd"}}

   ;; refer to user and psswd from project
   :min-lein-version "2.0.0")

看起来，顶部附近的:dependecies块格式错误(没有关闭的])，开发依赖关系实际上与:dev配置文件没有关联。我不确定:migratus是否属于:dev配置文件，所以在上面的示例中它不在它的范围之内。

FWIW，Leiningen回购中的样本工程文件是一个有用的资源。
