我正在使用Apache Hbase作爲其數據存儲的應用程序。我編寫了周圍的一些常見的HBase操作的Clojure的包裝,Lein部署在Clojars和依賴項上

https://github.com/mobiusinversion/hbase

,並推到clojars。

https://clojars.org/hbase

在我的HBase的包裝我導入字節類:

(ns hbase.table 
    (:gen-class) 
    (:refer-clojure :exclude [get]) 
    (:import [clojure.lang PersistentVector PersistentArrayMap] 
      [org.apache.hadoop.hbase.util Bytes] 
      [org.apache.hadoop.hbase.client Put Get HTable Scan])) 

然後在另一個項目叫「跆拳道」我宣佈包裝紙作爲依賴,而這種效果很好,它只是拉從clojars下來的罐子。

MacBook-Pro-2:wtf $ lein do clean, deps 
... blah blah 
Retrieving org/mortbay/jetty/jsp-2.1/6.1.14/jsp-2.1-6.1.14.jar from central 
Retrieving ant/ant/1.6.5/ant-1.6.5.jar from central 
Retrieving commons-el/commons-el/1.0/commons-el-1.0.jar from central

Retrieving hbase/hbase/0.1.1/hbase-0.1.1.jar from clojars 
MacBook-Pro-2:wtf $ 

然而字節類(和所有其他的Hadoop類)不能在新的項目中找到:

$ lein repl 
nREPL server started on port 58693 
REPL-y 0.1.10 
Clojure 1.5.1 
    Exit: Control+D or (exit) or (quit)

Examples from clojuredocs.org: [clojuredocs or cdoc] 
      (user/clojuredocs name-here) 
      (user/clojuredocs "ns-here" "name-here") 

user=> (use 'hbase.schema) 
ClassNotFoundException org.apache.hadoop.hbase.HTableDescriptor java.net.URLClassLoader$1.run (URLClassLoader.java:202) 

user=> (use 'hbase.config) 
ClassNotFoundException org.apache.hadoop.hbase.HBaseConfiguration java.net.URLClassLoader$1.run (URLClassLoader.java:202) 

user=> (use 'hbase.table) 
ClassNotFoundException org.apache.hadoop.hbase.util.Bytes java.net.URLClassLoader$1.run (URLClassLoader.java:202) 

user=> 

我不知道爲什麼Hadoop的類也不拉進與依賴由Leiningen提供,或者作爲我的clojars部署包裝。我怎樣才能讓這些類可見?

原來,這是關係到其依賴關係聲明的限定詞的順序:

這並沒有註冊HBase的依賴

(defproject hbase "0.1.0" 
:description "HBase Access in Clojure" 
:license {:name "Eclipse Public License" :url "http://www.eclipse.org/legal/epl-v10.html"} 
:url "https://github.com/mobiusinversion/hbase" 
:dependencies [ 
    [org.clojure/clojure "1.5.1"] 
     [org.apache.hadoop/hadoop-core "1.2.0"] 
    [org.apache.hadoop/hadoop-test "1.2.0" :scope "test"] 
    [org.apache.hbase/hbase "0.94.6.1" :classifier "tests" :scope "test"] 
    [org.apache.hbase/hbase "0.94.6.1"]] 
:plugins [[lein-marginalia "0.7.1"]]) 

然而,這:

(defproject hbase "0.1.3" 
:description "HBase Access in Clojure" 
:license {:name "Eclipse Public License" :url "http://www.eclipse.org/legal/epl-v10.html"}

    [org.apache.hadoop/hadoop-test "1.2.0"] 
    [org.apache.hbase/hbase "0.94.6.1" :classifier "tests" :scope "test"]] 
:plugins [[lein-marginalia "0.7.1"]])
