在ubuntu上安装CloudStack时解决构建时依赖性时出错.

Question

我在ubuntu上安装cloudstack,它使用maven来解决它的依赖关系.运行命令时出现以下错误mvn -P deps

[ERROR] The build could not read 1 project -> [Help 1] 
[ERROR]    
[ERROR]   The project org.apache.cloudstack:cloudstack:4.2.0 (/home/cloud/apache-cloudstack-4.2.0-src/pom.xml) has 1 error 
[ERROR]     Non-resolvable parent POM: Could not transfer artifact org.apache:apache:pom:11 from/to central (http://repo.maven.apache.org/maven2): repo.maven.apache.org: Name or service not known and 'parent.relativePath' points at wrong local POM @ line 14, column 11: Unknown host repo.maven.apache.org: Name or service not known -> [Help 2] 
[ERROR] 

我已经搜索了错误并在pom.xml中尝试了一些更改,但我没有得到解决方案.我不知道导致错误的是什么.

任何建议或最轻微的帮助都将得到承认.谢谢.

这是一个网络问题:

您的构建计算机无法访问http://repo.maven.apache.org/maven2

wget在命令行使用以检查您是否可以访问该网站.例如

root@mgmtserver:~/cm# wget http://repo.maven.apache.org/maven2
--2013-10-14 16:33:24--  http://repo.maven.apache.org/maven2
Resolving repo.maven.apache.org (repo.maven.apache.org)... 185.31.19.184, 185.31.19.185

wget可能失败的原因:

1. Maven回购暂时失败.等到它工作.
2. 构建计算机上没有网络适配器.检查它是否具有网络访问权限.
3. 您的代理设置不正确. 试试这个解决方案,或Maven迷你指南代理设置

背景:

Apache CloudStack的POM.xml继承了Apache Software Foundation Parent POM的预定义值.因此,Maven构建首先从网络位置下载所需的POM,Maven将其本地存储在Maven存储库中,这是一种本地缓存.

最后的评论:

如果你很好奇,下载POM的来源就在这里.
