Problem when trying to import SAT4J java class

[Ronan BARZIC]

Hi,

I'm trying to use the SAT4J java library (http://www.sat4j.org) from Clojure.

I've create a clojure app with "lein new app sat4j-app"

I've edited the project.clj file to :

(defproject sat4j-app "0.1.0-SNAPSHOT"

  :description "FIXME: write description"

  :url "http://example.com/FIXME"

  :license {:name "Eclipse Public License"

            :url "http://www.eclipse.org/legal/epl-v10.html"}

  :dependencies [

                 [org.clojure/clojure "1.5.1"]

                 [org.ow2.sat4j/org.ow2.sat4j.sat "2.3.5"]

                 [org.ow2.sat4j/org.ow2.sat4j.core "2.3.5"]  

                 ]

  :main sat4j-app.core

  :profiles {:uberjar {:aot :all}})

If I run lein deps, I can see that leiningen can find the sta4j modules :

....

Retrieving org/ow2/sat4j/org.ow2.sat4j.sat/2.3.5/org.ow2.sat4j.sat-2.3.5.pom from central

Retrieving org/ow2/sat4j/org.ow2.sat4j.pom/2.3.5/org.ow2.sat4j.pom-2.3.5.pom from central

Retrieving org/ow2/ow2/1.5/ow2-1.5.pom from central

Retrieving org/ow2/sat4j/org.ow2.sat4j.core/2.3.5/org.ow2.sat4j.core-2.3.5.pom from central

....

And I can compile and run the default code (no sat4j import yet).

The problem occurs when I try to use import in my main clojure code :

(ns sat4j-app.core

  (:gen-class)

  (:import org.ow2.sat4j/org.ow2.sat4j.core Vec ))

I then get a Class not found exception (Vec is suppoed to be defined in the core module)

I don't know which syntax to use in the import statement. 

I've also tried (:import org.ow2.sat4j.core Vec ), (:import org.ow2.sat4j.core.Vec ) without success.

To make think even more confusing, I did a local build of sat4j and I found (using javadoc html page) that the Vec class is defined as org.sat4j.core.Vec<T>

not org.ow2.sat4j.core.Vec<T>. 

So I tried (:import org.sat4j.core.Vec ) and (:import org.sat4j.core Vec ) without success.

Any clue ?

Thank you

Ronan

The form should be:

(:import [org.sat4j.core Vec]) ; note the square braces.

Thank - That fixed the problem - I was using an example from "Clojure Programming" (P 328) and they didn't use square braquets - probably a typo ?
