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

修改settings.xml:

    <mirror>  
        <id>nexus-osc</id>  
        <mirrorOf>*</mirrorOf>  
        <name>Nexus osc</name>  
        <url>http://maven.oschina.net/content/groups/public/</url>  
    </mirror>  

两份settings.xml,一份在maven安装目录C:Program FilesJavaapache-maven-3.3.9conf下，一份从这里拷贝到C:Program FilesJavamaven-repository下。
