eclipse创建maven项目，报错

报错如下：

Could not resolve archetype org.apache.maven.archetypes:maven-archetype-webapp:1.0 from any of the configured repositories.
Could not resolve artifact org.apache.maven.archetypes:maven-archetype-webapp:pom:1.0

一、重新下载maven-archetype-webapp-1.0.jar
方法为：进入maven本地仓库org\apache\maven\archetypes\maven-archetype-webapp\1.0目录下删除.lastUpdate文件，当再次创建web时项目时，ide会自动下载相关的jar包。
二、配置Catalog
在eclipse中，点击window-->preferences-->maven-->archetype,在archetype页面中点击 “Add Remote Catalog”,在弹出框的catalog File输入框中填写“http://repo1.maven.org/maven2/archetype-catalog.xml”（引号不要），下面description根据自己喜好填写。然后再次创建maven项目时选择自己刚才新建的catalog，然后再选择 org.apache.maven.archetypes maven-archetype-webapp；

我尝试重新下载解决了问题。
