很高兴能够手动学习这个,因为理解类路径会让世界变得更美好.在实践中,许多Clojurians使用leiningen,maven或cake.

我个人推荐使用leiningen:

• wget http://github.com/technomancy/leiningen/raw/stable/bin/lein
• 使这个excutable并保存在像〜/ bin或/ usr/bin或其他任何地方.
• lein new MY-PROJECT-NAME
• 莱恩德普
• 莱恩代表
• 砍掉了!

有很多理由不使用自动化工具,这些东西并不适合所有人.即使对于简单的单线程,设置它的时间也是值得的.
