問題安裝OpenNLP

Question

我在安裝OpenNLP時遇到問題。我希望Stack的蜂巢式智慧能夠幫助我走出困境。我承認我不太熟悉Java擴展/插件，所以任何幫助將不勝感激。

我已經安裝了Maven。當我運行mvn --version我收到以下：

Apache Maven 3.0.4 (r1232337; 2012-01-17 03:44:56-0500) 
Maven home: /Users/[my_name]/apache-maven-3.0.4 
Java version: 1.6.0_33, vendor: Apple Inc. 
Java home: /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home 
Default locale: en_US, platform encoding: MacRoman 
OS name: "mac os x", version: "10.7.4", arch: "x86_64", family: "mac" 

當我去到OpenNLP目錄，/Users/[my_name]/apache-opennlp-1.5.2，並運行mvn clean install，我收到此錯誤：

[INFO] Scanning for projects...

[ERROR] For more information about the errors and possible solutions, please read the following articles:

我不完全理解這個錯誤。如果有人能解釋我需要做什麼來解決它，我會非常感激。

從opennlp文件夾內執行命令：/Users/[my_name]/apache-opennlp-1.5.2/opennlp。欲瞭解更多詳情，請查閱building documentation。
