You could put it directly in your classpath, like you're doing with clojure.jar. If both were in the current directory, you would start clojure with 

<pre><code>java -cp clojure-1.3.0.jar:numeric-tower.jar clojure.main
</code></pre>

(or windows)

<pre><code>java -cp clojure-1.3.0.jar;numeric-tower.jar clojure.main
</code></pre>

However, if that project is on clojars or in the maven repositories, its easier to use <a href="https://github.com/technomancy/leiningen" rel="nofollow">leiningen</a>. It can take a lot of the hassle out of that sort of thing.

blocks|key|475761|text|我昨天也遇到了同样的问题(也是作为Clojure的新手)。据我所知，在Clojure+1.2和1.3之间，他们将许多contrib库拆分到单独的项目中，以便更容易管理。并缩小Clojure的核心。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|475762|完成你想要做的事情的最简单的方法是通过leiningen+(我昨天晚上在#clojure+IRC频道的技术方面得到了这个答案)。建议使用leiningen创建一个“游乐场”项目，您可以在其中玩耍并学习Clojure。|475763|因此，使用以下命令创建一个游乐场项目：|475764|lein+new+playground|code-block|syntax|javascript|475765|修改project.clj文件以包括：|475766|[org.clojure/math.numeric-tower+"0.0.1"]|475767|作为依赖项。有人告诉我，http://search.maven.org/是找出哪个是特定库的最新版本的最简单方法。|offset|length|475768|然后，运行|475769|lein+deps|475770|把罐子拉起来。现在你已经准备好了|475771|lein+repl|475772|才能上路。|475773|一旦启动了repl，就拉入numeric-+in：|475774|(require+'[clojure.math.numeric-tower+:as+math])|475775|然后，您可以执行expt调用：|475776|(math/expt+4+6)+;;+yields+4096|475777|希望这能有所帮助！|475778|entityMap|0|LINK|mutability|MUTABLE|url|http://search.maven.org/^0|0|0|0|0|0|0|C|O|0|0|0|0|0|0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|1K|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|1L|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|1M|8|@]|9|@]|A|$]]|$1|F|3|G|5|H|7|1N|8|@]|9|@]|A|$I|J]]|$1|K|3|L|5|6|7|1O|8|@]|9|@]|A|$]]|$1|M|3|N|5|H|7|1P|8|@]|9|@]|A|$I|J]]|$1|O|3|P|5|6|7|1Q|8|@]|9|@$Q|1R|R|1S|1|1T]]|A|$]]|$1|S|3|T|5|6|7|1U|8|@]|9|@]|A|$]]|$1|U|3|V|5|H|7|1V|8|@]|9|@]|A|$I|J]]|$1|W|3|X|5|6|7|1W|8|@]|9|@]|A|$]]|$1|Y|3|Z|5|H|7|1X|8|@]|9|@]|A|$I|J]]|$1|10|3|11|5|6|7|1Y|8|@]|9|@]|A|$]]|$1|12|3|13|5|6|7|1Z|8|@]|9|@]|A|$]]|$1|14|3|15|5|H|7|20|8|@]|9|@]|A|$I|J]]|$1|16|3|17|5|6|7|21|8|@]|9|@]|A|$]]|$1|18|3|19|5|H|7|22|8|@]|9|@]|A|$I|J]]|$1|1A|3|1B|5|6|7|23|8|@]|9|@]|A|$]]|$1|1C|3|-4|5|6|7|24|8|@]|9|@]|A|$]]]|1D|$1E|$5|1F|1G|1H|A|$1I|1J]]]]

I had this same issue yesterday (also as a newcomer to Clojure). From my understanding, between Clojure 1.2 and 1.3 they split out many of the contrib libraries into separate projects so that they could be managed more easily. And shrink the core of what Clojure is.

The easiest way to accomplish what you're trying to do is through leiningen (I got this answer from technomancy in the #clojure IRC channel yesterday evening). The recommendation is to create a "playground" project using leiningen that you can play around in and learn Clojure.

So, create a playground project with:

<pre><code>lein new playground
</code></pre>

Modify the project.clj file to include:

<pre><code>[org.clojure/math.numeric-tower "0.0.1"]
</code></pre>

as a dependency. I was told that <a href="http://search.maven.org/" rel="noreferrer">http://search.maven.org/</a> is the easiest way to find out which is the most up-to-date version of a particular library.

Then, run

<pre><code>lein deps
</code></pre>

to pull in the jars. Now you're ready to 

<pre><code>lein repl
</code></pre>

to get going.

Once the repl is started, pull in numeric-tower:

<pre><code>(require '[clojure.math.numeric-tower :as math])
</code></pre>

Then you can do your expt call:

<pre><code>(math/expt 4 6) ;; yields 4096
</code></pre>

Hope that helps!

blocks|key|475828|text|感谢所有人。它现在起作用了。事实上，真正让我困惑的问题是java不能理解类路径中冒号后面的~+(linux+home)符号。我在做|type|unstyled|depth|inlineStyleRanges|entityRanges|data|475829|java+-cp+~/Clojure/clojure-1.3.0/clojure-1.3.0.jar:~/Clojure/lib++clojure.main|code-block|syntax|javascript|475830|而java并不理解这一点。|475831|但是，如果您这样做|475832|java+-cp+~/Clojure/clojure-1.3.0/clojure-1.3.0.jar:/home/username/Clojure/lib++clojure.main|475833|它起作用了。|475834|类路径变量的奇怪行为。|475835|我会使用lein，但由于我正在考虑为android做一些编程，我想如果我能理解所有这些只在java中是如何工作的，那会更好。除非lein也可以打包android项目？|475836|不管怎样，谢谢。所有三个回复都提供了非常丰富的信息。|475837|entityMap^0|0|0|0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|W|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|X|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Y|8|@]|9|@]|A|$]]|$1|I|3|J|5|6|7|Z|8|@]|9|@]|A|$]]|$1|K|3|L|5|D|7|10|8|@]|9|@]|A|$E|F]]|$1|M|3|N|5|6|7|11|8|@]|9|@]|A|$]]|$1|O|3|P|5|6|7|12|8|@]|9|@]|A|$]]|$1|Q|3|R|5|6|7|13|8|@]|9|@]|A|$]]|$1|S|3|T|5|6|7|14|8|@]|9|@]|A|$]]|$1|U|3|-4|5|6|7|15|8|@]|9|@]|A|$]]]|V|$]]

Thanks to all. It works now.
In fact the problem that really confused me was that java didn't understand the ~ (linux home) symbol after a colon in the classpath.
I was doing

<pre><code>java -cp ~/Clojure/clojure-1.3.0/clojure-1.3.0.jar:~/Clojure/lib clojure.main
</code></pre>

and java doesn't understand that.

However, if you do

<pre><code>java -cp ~/Clojure/clojure-1.3.0/clojure-1.3.0.jar:/home/username/Clojure/lib clojure.main
</code></pre>

it works.

Strange behavior of the classpath variable.

I would have used lein, but since I'm considering doing some programming for android, I thought it would be better if I could understand how all this work with java only. Unless lein can package android project as well?

Anyway, thanks. All three replies were very informative.

I try to learn a bit of Clojure because the language looks nice.
But it seems that there is no info anywhere on how to install/use libraries like for example the clojure.math.numeric-tower.

For now I run the REPL by typing this in my Linux shell:

<pre><code>java -cp ~/Clojure/clojure-1.3.0/clojure-1.3.0.jar clojure.main
</code></pre>

I downloaded the numeric-tower jar, and put it everywhere. I have modified the -cp option in every possible way. I have put the numeric_tower.clj file everywhere.
It still doesn't work.

What's the way to use the libraries?

Using clojure.math.numeric-tower, or any library

Linux

我试着学习一点Clojure，因为它看起来很不错。但是似乎没有关于如何安装/使用诸如clojure.math.numeric- to之类的库的信息。现在，我通过在Linux shell中输入以下命令来运行REPL：java -cp ~/Clojure/clojure-1.3.0/clojure-1.3.0.jar  c...
