Eclipse에서 maven-archetype-webapp 프로젝트를 만들었습니다. 그리고 Java에서 Clojure 코드를 사용하려고합니다. 그래서, 내 core.clj 파일이 있습니다 :java와 clojure를 사용하여 Eclipse에서 maven 동적 웹 프로젝트를 만들려고 시도했습니다.
(ns coq.core
(:gen-class
:name coq.core
:methods [#^{:static true} [foo [int] void]]))
(defn -foo [i] (println "Hello from Clojure. My input was " i))
(defn -main [] (println "Hello from Clojure -main."))
의 pom.xml :
