一、问题描述：
使用MyEclipse10自带的Maven插件创建Web项目时报错：
Could not resolve archetype org.apache.maven.archetypes:maven-archetype-webapp:RELEASE from any of the configured repositories.
Could not resolve artifact org.apache.maven.archetypes:maven-archetype-webapp:pom:RELEASE
Failed to resolve version for org.apache.maven.archetypes:maven-archetype-webapp:pom:RELEASE: Could not find metadata org.apache.maven.archetypes:maven-archetype-webapp/maven-metadata.xml in local (C:\Users\liujunguang\.m2\repository)
Failed to resolve version for org.apache.maven.archetypes:maven-archetype-webapp:pom:RELEASE: Could not find metadata org.apache.maven.archetypes:maven-archetype-webapp/maven-metadata.xml in local (C:\Users\liujunguang\.m2\repository)
二、解决方法
1、在MyEclipse Maven配置中添加新的Catalog配置：
http://repo1.maven.org/maven2/archetype-catalog.xml
2、接下来在使用刚添加的catalog创建web工程
