Clojure的java.lang.NoClassDefFoundError調用CLJ-時間/最後一天的最月

Question

我叫

(clj-time.core/last-day-of-the-month 1999 2) 

和

(clj-time.core/number-of-days-in-the-month 1999 2) 

當兩個罰球

java.lang.NoClassDefFoundError org/joda/time/DateTime$Property org.joda.time.DateTime.dayOfMonth (DateTime.java:1971) 

該文檔說：

(defn last-day-of-the-month 
    ([^long year ^long month] 
     (last-day-of-the-month- (date-time year month))) 
    ([dt] 
     (last-day-of-the-month- dt))) 

(defn number-of-days-in-the-month 
    (^long [^DateTime dt] 
     (day (last-day-of-the-month- dt))) 
    (^long [^long year ^long month] 
     (day (last-day-of-the-month- (date-time year month))))) 

我犯了什麼錯誤？

謝謝！

以下是我的項目設置和依賴：

---

(defproject xxx "0.1.2-SNAPSHOT" 
:description "" 
:dependencies [[org.clojure/clojure "1.8.0"] 

... 
      [clj-time "0.11.0"]   

...) 

，我在項目REPL試過這樣：

clj-time=> clj-time.core/last-day-of-the-month 
#object[clj_time.core$last_day_of_the_month 0x6a86b560 "clj_time.core$last_day_of_the_month@6a86b560"] 

---

上述結果是從REPL服務器獲取我通過ssh進行連接。

當我在本地項目文件夾中運行lein repl，我能得到正確的結果：

xxx.core=> (clj-time.core/last-day-of-the-month 2016 2) 
#object[org.joda.time.DateTime 0x22a0534e "2016-02-29T00:00:00.000Z"] 
xxx.core=> (clj-time.core/number-of-days-in-the-month 2016 2) 
29 

我是新來的Clojure。這些信息有用嗎？

重新啓動repl後，現在問題就解決了。

Answer 1

非常適合我。

project.clj：

(defproject clj "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 "1.9.0-alpha13"] 
    [clj-time "0.12.0"] 
    ] 
    :java-source-paths ["/home/alan/xpr/src"] 
    :main ^:skip-aot clj.core 
    :target-path "target/%s" 
    :profiles {:dev  {:dependencies [[org.clojure/test.check "0.9.0"]] } 
      :uberjar {:aot :all}} 
) 

主程序：

(ns clj.core 
    (:require 
    [clj-time.core :as tm] 
)) 

(println :day (tm/last-day-of-the-month 1999 2)) 

(println :days (tm/number-of-days-in-the-month 1999 2)) 

(defn -main [& args]) 

結果：

~/clj > lein run  
:day #object[org.joda.time.DateTime 0x61884cb1 1999-02-28T00:00:00.000Z] 
:days 28
