Java - Maven - OpenImaj項目組裝錯誤

Question

我正在嘗試使用maven和OpenImaj庫組裝項目，我一直按照此頁面上的說明http://www.openimaj.org/tutorial/getting-started-with-openimaj-using-maven.html，但其中一些過程似乎不同於教程，我已經試過這兩個不同的計算機（MAC和PC），並收到以下錯誤/步驟，任何想法在哪裏/我做錯了什麼將有所幫助。

1. 運行MVN -DarchetypeCatalog = http://maven.openimaj.org/archetype-catalog.xml原型之後：生成線我提示「選擇一個數或應用過濾器」，其中缺省值是284

2. 一旦我選擇284（I應該是選擇其他任何東西？），我正在提示選擇「maven-archetype-quickstart版本」，我選擇最新的6：1.1，後面跟着groupId，artifactId，版本，軟件包和Y確認，這個結果是'Build成功「，並在我的電腦上創建目錄以及pom.xml文件。

3. 當我導航到項目文件夾「cd projectName」並運行mvn assembly：assembly命令時，我首先看到正在收集一些軟件包，然後看到「Build Failure」通知 - 「Failed執行目標org.apache.maven.plugins：Maven的組裝插件：2.2-β-5 ....發現彙編描述

任何知道我做錯了，我怎樣才能得到。 OpenImaj庫集成到一個項目中，我應該下載SVN版本並嘗試從本地庫設置項目。

非常感謝提前！

您確定您正確輸入了步驟1中的maven命令嗎？您應該只看到三個選項（剛剛確認這是工作在兩個OSX，Debian的Ubuntu的&）：

abe:~ jon$ mvn -DarchetypeCatalog=http://maven.openimaj.org/archetype-catalog.xml archetype:generate

Choose archetype: 
1: http://maven.openimaj.org/archetype-catalog.xml -> org.apache.maven.archetypes:maven- archetype-quickstart (An archetype which contains a sample Maven project.) 
2: http://maven.openimaj.org/archetype-catalog.xml -> org.openimaj:openimaj-quickstart-archetype (Maven quickstart archetype for OpenIMAJ) 
3: http://maven.openimaj.org/archetype-catalog.xml -> org.openimaj:openimaj-subproject-archetype (Maven archetype for creating OpenIMAJ subprojects with the most of the standard configuration completed automatically) 
Choose a number or apply filter (format: [groupId:]artifactId, case sensitive contains):  

然後，您需要選擇從列表中（可能＃2）org.openimaj:openimaj-quickstart-archetype選項。

Answer 2

當我在工作場所的另一個無線網絡中工作時，我能夠繼續這個過程。有沒有可能會限制maven與我的家庭網絡的功能？

雖然即使在選項中選擇正確的原型目錄，我仍然得到一個構建失敗的錯誤，這裏是日誌 - 任何方向將再次

感謝有這方面的想法可以理解

Answer 3

我曾遇到過類似的問題，最後解決了它。這裏需要注意兩點。一個是我們正在使用的網絡，其次是我們正在使用的maven工具。

在你的eclipse IDE中，轉到window - >首選項。

在maven標籤下轉到安裝子選項卡。而不是使用嵌入式Maven添加文件路徑來安裝在系統上的maven（一個命令行使用）。

在常規選項卡下，轉到網絡連接選項卡。更改活動提供程序。

以上都不會完全成功地一次性構建項目。但是網絡和maven的每個組合都會下載一些jar文件。一旦你嘗試兩到三個組合，你將擁有所有的罐子，並且項目將成功建立。

只需將此插件添加到您的pom.xml。這解決了我的問題：關於第一個問題

<build> 
    <plugins> 
     <plugin> 
     <groupId>org.apache.maven.plugins</groupId> 
     <artifactId>maven-assembly-plugin</artifactId> 
     <configuration> 
     <descriptorRefs> 
     <descriptorRef>jar-with-dependencies</descriptorRef> 
     </descriptorRefs> 
     </configuration> 
     </plugin> 
    </plugins>
