Maven报错：maven-archetype-webapp:RELEASE from any of the configured repositories

今天学习maven，在控制台下新建maven项目没有问题，但是在STS(eclipse)下创建maven项目老是报错，郁闷死了：

----------------------------------------------------

错误信息：Could not resolve archetype org.apache.maven.archetypes:maven-archetype-webapp:RELEASE from any of the configured repositories.
Could not resolve artifact
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 (F:\maven\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 (F:\maven\repository)

----------------------------------------------------

遇到问题，就是baidu/google查找解决方法，可惜网上很多人提到的方法试了都不行，郁闷了好几个小时，最后找到问题原因如下：

 

以上报错的原因是：在settings.xml 文件中 mirrors出了问题。默认maven3.1.0安装目录下的conf目录下的setting.xml配置文件中的mirrors配置是这样的：

 

  <mirrors>
    <!-- mirror
     | Specifies a repository mirror site to use instead of a given repository. The repository that
     | this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used
     | for inheritance and direct lookup purposes, and must be unique across the set of mirrors.
     |
    <mirror>
      <id>mirrorId</id>
      <mirrorOf>repositoryId</mirrorOf>
      <name>Human Readable Name for this Mirror.</name>
      <url>http://my.repository.com/repo/path</url>
    </mirror>
     -->
  </mirrors>

 

我也不是很清楚为什么就是不行（猜测是maven默认的internet仓库里的文件不全，所以就添加了大家用得最多的maven的internet仓库之一：lbiblio，基本所有的开源的框架的jar文件都有提供），然后在setting.xml配置文件上面我添加了一个新的mirror，添加后如下：

 

  <mirrors>
    <!-- mirror
     | Specifies a repository mirror site to use instead of a given repository. The repository that
     | this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used
     | for inheritance and direct lookup purposes, and must be unique across the set of mirrors.
     |
    <mirror>
      <id>mirrorId</id>
      <mirrorOf>repositoryId</mirrorOf>
      <name>Human Readable Name for this Mirror.</name>
      <url>http://my.repository.com/repo/path</url>
    </mirror>
     -->
     <!--以下是新增加上去的-->
     <mirror> 
        <id>ibiblio.org</id> 
        <name>ibiblio Mirror of http://repo1.maven.org/maven2/</name> 
        <url>http://mirrors.ibiblio.org/pub/mirrors/maven2</url> 
        <mirrorOf>central</mirrorOf> 
     </mirror> 

  </mirrors>

 

 

就只是修改了setting.xml配置文件上的这个地方，然后在控制台下我重新输入：

mvn help：system

回车，就可以看到重新下载了好多的jar包文件。

等下载完成后，再在eclipse新建maven项目就正常了。
