Hello,
I am trying to compile a project with lein. The program source files
can be interpreted successfully (using swank-clojure) but when I try
to do "lein compile" or "lein jar" I get:
Exception in thread "main" java.lang.ClassCastException:
clojure.lang.PersistentVector cannot be cast to clojure.lang.Named

Compilation failed.
The source code looks like:
(ns graphcluster.colorize-map
(:gen-class)
(:use clojure.contrib.command-line)
(:require graphcluster.core)
(:require clojure.contrib.str-utils)
)
; function definitions, they all run in swank-clojure
(defn -main [& args]
(let [lines (line-seq (java.io.BufferedReader. *in*)
]
(print (colorize (clojure.contrib.str-utils/str-join "\n"
lines)))
))
In graphcluster.core there are some defs. I have for instance a sketch
object from incanter.processing .
I am using leiningen 1.5.2 and Clojure 1.2. Do you have any ideas
about the nature of this error?
Thanks!
Arnoldo
