java - lein 编译问题 (Clojure)

Question

我已经尝试寻找解决方案 3 个小时了，但没有任何帮助。有一个 lein 项目具有这样的 project.clj:

(defproject funcs "0.1.0-SNAPSHOT"
  :description "FIXME: write description"
  :url "http://example.com/FIXME"
  :license {:name "Eclipse Public License"
            :url "http://www.eclipse.org/legal/epl-v10.html"}
  :dependencies [[org.clojure/clojure "1.8.0"]
                 [org.xerial/sqlite-jdbc "3.7.2"]])

还有一个 core.clj header :

(ns funcs.core
  (:gen-class)
  (:import (java.sql.Connection)
           (java.sql.DriverManager)
           (java.sql.ResultSet)
           (java.sql.SQLException)
           (java.sql.Statement))
  (:require [clojure.string    :as str]
            [clojure.java.jdbc :as j])) ; JDBC Driver for SQLite

在lein deps之后，我尝试编译core.clj，但是得到:

Compiling src/funcs/core.clj

所以我不知道问题出在哪里。请帮忙=)

Answer 1

my-functions.core 应该是命名空间定义中的 funcs.core 。所以而不是:

(ns my-functions.core ...)

有:

(ns funcs.core ...)

问题是命名空间的名称和文件所在目录的名称似乎不一致。另一种解决方案是将目录名称从 funcs 更改为 my-functions。
