我是Linux和Maven的新手。我想让maven工作，所以我可以安装Mahout。我对这个过程不仅仅有一个问题，但我会关注最基本的问题：
我正在尝试关注this guide 学习如何开始使用maven。当我在终端
中运行以下命令时mvn archetype:generate -DgroupId=com.mycompany.app -DartifactId=my-app -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false
我收到以下错误：
dave@CodeKingdom:~/workspace/maven_test$ mvn archetype:generate -DgroupId=com.mycompany.app -DartifactId=my-app -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false

我无法理解那里的资源。根据我的谷歌搜索收集的是，maven无法连接到互联网下载必要的文物。但是我不确定是否应该修改setting.xml或pom.xml来修复它，或者我是否应该做一些完全不同的事情。另外，我似乎无法在我的maven文件夹中找到pom.xml文件。有一个settings.xml文件，但我不清楚如何或是否应该修改它。 任何帮助表示赞赏。
