从jar中导入clojure函数(Importing clojure functions from jars)

从jar中导入clojure函数(Importing clojure functions from jars)

我正在玩Clojure，我无法弄清楚如何从clojure-contrib.jar导入一个函数。 根据这个答案，我正在做以下事情：

像这样运行REPL：

java -cp clojure.jar:clojure-contrib.jar clojure.main

然后尝试导入一个函数：

user=> (use '[clojure-contrib.duck-streams :only (writer reader)])

它不起作用，我收到以下错误：

java.io.FileNotFoundException：找不到类路径上的clojure_contrib / duck_streams__init.class或clojure_contrib / duck_streams.clj：（NO_SOURCE_FILE：0）

尝试使用点而不是破折号也不起作用：

user=> (use '[clojure.contrib.duck-streams :only (writer reader)])

我得到的主要是同样的错误：

java.io.FileNotFoundException：找不到类路径上的clojure / contrib / duck_streams__init.class或clojure / contrib / duck_streams.clj：（NO_SOURCE_FILE：0）

我究竟做错了什么？

I'm playing around with Clojure, and I can't figure out how to import a function from clojure-contrib.jar. Working from this answer, I'm doing the following:

Running the REPL like so:

java -cp clojure.jar:clojure-contrib.jar clojure.main

Then trying to import a function:

user=> (use '[clojure-contrib.duck-streams :only (writer reader)])

It doesn't work, and I get the following error:

java.io.FileNotFoundException: Could not locate clojure_contrib/duck_streams__init.class or clojure_contrib/duck_streams.clj on classpath: (NO_SOURCE_FILE:0)

Trying it with a dot instead of a dash also doesn't work:

user=> (use '[clojure.contrib.duck-streams :only (writer reader)])

I get mostly the same error:

java.io.FileNotFoundException: Could not locate clojure/contrib/duck_streams__init.class or clojure/contrib/duck_streams.clj on classpath: (NO_SOURCE_FILE:0)

What am I doing wrong?

最满意答案

这应该工作

(use 'clojure.contrib)

我现在没有方便检查，但是

(use 'clojure.contrib :only (writer reader))

也应该工作

This should work

(use 'clojure.contrib)

I don't have clojure handy right now to check, but

(use 'clojure.contrib :only (writer reader))

should also work
