lein编译问题(Clojure)

标签: java import clojure require leiningen

我一直试图找到一个解决方案3个小时,没有任何帮助。 有一个lein项目有 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"]])

同样,还有一个标题为 core.clj

(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

lein deps之后我尝试编译 core.clj ,但得到:

所以我不知道问题出在哪里。帮助plz =)

您的命名空间定义中

my-functions.core应为funcs.core。所以而不是:

(ns my-functions.core ...)

有:

(ns funcs.core ...)

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