I am new to Clojure and working on a project where I am trying to extract text from web pages using Pantomime. I am managing the project with Leiningen and editing using Eclipse / CCW. When I try to use the pantomime.extract/extract function, I get the following error:
Exception in thread "main" java.lang.NoClassDefFoundError: Could not initialize class org.apache.tika.parser.pkg.PackageParser, compiling:(/tmp/form-init7461469090551574085.clj:1:72)

ABRT problem creation: 'success'
I made sure to include the appropriate dependency line in my project.clj:
[com.novemberain/pantomime "2.6.0"]
I also made sure that I am requiring the pantomime.extract namespace in my namespace:
(ns com.scrape
(:require [pantomime.extract :as extract]))
Here is the function that is calling "extract":
(defn extract-text [url]
(:text (extract/parse (java.net.URL. url))))
I have tried running "lein clean" and "lein deps". I've also deleted the directory where leiningen stores dependencies (~/.m2) and allowed lein to automatically re-download all the appropriate jar files. Still, whether I am running an REPL from the command line with "lein run" or from Eclipse, I always get the above error.
Why am I getting this error, and how can I fix it?
UPDATE
I tried to recreate this issue in a new project with as little code as possible in order to post the full source here; however, in a new lein project, I was able to copy all my code from my original project; and I am not getting errors anymore.
Any idea what might have happened? Some glitch with leiningen?
