问题描述：
使用Eclipse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\test\.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\test\.m2\repository)
在Eclipse Maven配置中添加新的Catalog配置：
- http://repo1.maven.org/maven2/archetype-catalog.xml
接下来在使用刚添加的catalog创建web工程
