MyEclipse创建maven项目报错?

大家好我安装了maven3,MyEclipse设置了maven下的setting.xml,但是创建项目时报错:Could not resolve archetype org.apache.maven.archetypes:maven-archetype-quickstart:RELEASE from any of the configured repositories.
Could not resolve artifact org.apache.maven.archetypes:maven-archetype-quickstart:pom:RELEASE
Failed to resolve version for org.apache.maven.archetypes:maven-archetype-quickstart:pom:RELEASE: Could not find metadata org.apache.maven.archetypes:maven-archetype-quickstart/maven-metadata.xml in local (F:\Learing\Maven\LocalMaven)
在本地工厂中确实没有maven-metadata.xml,是不是在创建项目时下载这个啊?我的是win10系统,在win7上没有出现这种情况,还有就是有的说设置代理,请问这个代理是干什么的?对大神教教我,谢谢了,,,

maven下的setting.xml属于全局配置,maven安装后的本地默认仓库是~/.m2;如果使用Nexus搭建了私有仓库,可在你的~/.m2/settings.xml文件中添加
<?xml version="1.0"?>
