Is any package or jar file required for Lancet in clojure?

Programmin Clojure by "Stuart Halloway" book talks about Lancet, Very first step is (use 'lancet) which is throwing some Exception,

Exception user=> (use 'lancet) java.io.FileNotFoundException: Could not locate lancet__init.class or lancet.clj on classpath: (NO_SOURCE_FILE:0)

Is any jar fi开发者_开发知识库le or some package is required to make this work?

You need lancet installed to use lancet. I'm surprised the book doesn't mention anything like that. Anyway, I would strongly recommend you use leiningen instead. Lancet is out of date and leiningen is the most popular build tool for clojure these days.
