运行 Midje 测试时出现 FileNotFoundexception

Question

我有一个使用 Midje 库进行测试的 Leiningen 项目。但是我无法运行任何测试，以防lein test 我得到

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

所以我猜这是因为我错误地定义了带有依赖项的 dev 配置文件，但我不确定真正的问题在哪里。

作为奖励，我也无法让environ 工作，我总是得到nil，我想从env 地图中提取一些属性（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"]]

我没有尝试过，但结构看起来不太正确。我认为应该是这样的：

(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")

看起来您靠近顶部的:dependecies 块格式错误（没有关闭]），并且开发依赖项实际上与:dev 配置文件无关。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内。

FWIW，Leiningen 存储库中的 sample project 文件是一个有用的资源。
