从 jar 导入 clojure 函数
我正在使用 Clojure，但不知道如何从 clojure-contrib.jar 导入函数。根据 this 答案，我正在执行以下操作
：像这样 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，并且出现以下错误：
java.io.FileNotFoundException：无法在类路径上找到 clojure_contrib/duck_streams__init.class 或 clojure_contrib/duck_streams.clj：(NO_SOURCE_FILE:0)
用点而不是破折号尝试也不起作用：
user=> (use '[clojure.contrib.duck-streams :only (writer reader)])
我得到的错误大多相同：
java.io.FileNotFoundException：无法在类路径上找到 clojure/contrib/duck_streams__init.class 或 clojure/contrib/duck_streams.clj：(NO_SOURCE_FILE:0)
我做错了什么？
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?

clojure.jar和clojure-contrib.jar是否在您当前的工作目录中？如果没有，您需要在 CLASSPATH 中指定 JAR 文件的完整路径。Is
clojure.jarandclojure-contrib.jarin your current working directory? If not, you need to specify the full path to the JAR files in the CLASSPATH.这应该可以工作
我现在没有 clojure 方便检查，但
也应该可以工作
This should work
I don't have clojure handy right now to check, but
should also work
它是 clojure.contrib，而不是 clojute-contrib。注意点与破折号。
It's clojure.contrib, not clojute-contrib. Note dot versus dash.
