clojure - 热修复“警告：任何？已经引用：#'clojure.core/any？在命名空间：leiningen.midje，被替换为：#'leiningen.midje/any？”

Question

我正在尝试lein new compojure financeiro使用 midje 框架在 leiningen 的 compojure 模板 () 中运行测试并收到警告：

lein midje
WARNING: any? already refers to: #'clojure.core/any? in namespace: leiningen.midje, being replaced by: #'leiningen.midje/any?
nil
All checks (3) succeeded.

我的测试代码handler_test.clj：

(ns financeiro.handler-test
  (:require
    ; [clojure.test :refer :all]
    [midje.sweet :refer :all]
    [ring.mock.request :as mock]
    [financeiro.handler :refer :all]))

; (deftest test-app
;   (testing "main route"
;     (let [response (app (mock/request :get "/"))]
;       (is (= (:status response) 200))
;       (is (= (:body response) "Hello World"))))

;   (testing "not-found route"
;     (let [response (app (mock/request :get "/invalid"))]
;       (is (= (:status response) 404)))))

(facts "'Hello World' main route"
  (fact "response status is 200"
    (let [response (app (mock/request :get "/"))]
      (:status response)=> 200))

  (fact "body text is 'Hello World'"
    (let [response (app (mock/request :get "/"))]
      (:body response)=> "Hello World")))

(facts "not-found route"
  (fact "response status is 404"
    (let [response(app (mock/request :get "/invalid"))]
      (:status response)=> 404)))

我的项目文件project.clj：

(defproject financeiro "0.1.0-SNAPSHOT"
  :description "FIXME: write description"
  :url "http://example.com/FIXME"
  :min-lein-version "2.0.0"
  :dependencies [
    [org.clojure/clojure "1.10.0"]
    [compojure "1.6.1"]
    [ring/ring-defaults "0.3.2"]
  ]
  :plugins [
    [lein-ring "0.12.5"]
  ]
  :ring {
    :handler financeiro.handler/app
  }
  :profiles {
    :dev {
      :dependencies [
        [javax.servlet/servlet-api "2.5"]
        [ring/ring-mock "0.3.2"]
        [midje "1.9.8"]
      ]
      :plugins [
        [lein-midje "3.2.1"]
      ]
    }
  }
)

clojure.test当我使用( )运行默认测试时lein test，我没有收到警告，但是当我使用midje.sweet( lein midje) 运行时，我收到有关“命名空间：leiningen.midje”和“替换 #'clojure.core/any? 到 #'leiningen.midje/any?' ，我在网上寻找解决方案，但我没有找到这个特定的警告(leiningen/compojure/midje)，我是 clojure 和 midje 的初学者。我现在正在学习。我可以在哪个文件中替换这个命名空间？有简单的解决方案可以消除此警告吗？或者这是框架 midje 中的一个错误？

这不会干扰测试的执行，但是每次运行测试时都看到这条消息很烦人。

注意：我也尝试过之前版本的 midje [midje "1.9.6"]，但没有成功！

这个特殊问题在这个 Pull Request中得到了解决。

对于一般情况，您可以通过从另一个命名空间中排除（=取消引用）您想要的符号来消除此警告（当它来自您的代码时）clojure.core

这是来自不同背景的示例：

警告

(ns urbest.apheleia.system.typography
  (:require [garden.units :refer [rem]]))

WARNING: rem already refers to: #'clojure.core/rem in namespace: urbest.apheleia.system.typography, being replaced by: #'garden.units/rem

没有更多警告

(ns urbest.apheleia.system.typography
  (:refer-clojure :exclude [rem])
  (:require [garden.units :refer [rem]]))
