我正在尝试将 midje“事实”与我的源代码一起包含在使用 aot 的项目中。尝试访问 repl 或运行项目会导致以下错误，我已经包含了一个重现该问题的最小示例项目。谢谢你的帮助！

项目.clj

(defproject test-midje "0.1.1"
  :description "Why doesn't midje work?"
  :min-lein-version "2.0.0"
  :source-paths ["src/clj"]
  :repl-options {
                 :timeout 120000
                 }
  :main org.midjetest.core
  :profiles {:dev {:dependencies [[midje "1.5.0"]]}}
  :aot [org.midjetest.core])

src/clj/org/midjetest/core.clj

(ns org.midjetest.core
  (:require [midje.sweet :refer [fact facts]]))


(defn addtwo [a] (+ 2 a))

(fact "addtwo adds two to numbers"
      (addtwo 3) => 5)


(defn -main
  "testing with main"
  ([] (println (addtwo 5))))

lein run或lein repl给出以下错误：

这里的根本问题是 Bootstrap.clj 在 AOT-ed 时不起作用；它取决于在加载之前加载的某些命名空间；然而，clojure AOTed 类的静态初始化器或多或少等同于：

(binding [clojure.core/*ns* nil clojure.core/*fn-loader* loader clojure.core/*read-eval* true] (my.class/load))

由于在 midje.sweet 定义它自己的 ns ( https://github.com/marick/Midje/blob/master/src/midje/sweet.clj#L2 )之前调用 Bootstrap/bootstrap ，因此*ns*保持为空并(ns-name *ns*)崩溃。

我认为您无法完成这项工作，除非 midje 的引导代码发生更改。我建议将您的测试放入单独的文件中，而不是使用这些文件。
