idea设置maven

1.打开idea中的setting

2.搜索框搜索maven,下面找到maven

右侧显示就是maven的设置界面

3.配置maven

后续还需要配置一个地方是本地仓库的优先，在runner-VM Options里面填写一下代码

-DarchetypeCatalog=internal

5.如果想要修改maven的镜像，修改conf中的settings.xml文件

 <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>
     -->
	  <mirror>
        <id>nexus-aliyun</id>
        <mirrorOf>*</mirrorOf>
        <name>Nexus aliyun</name>
        <url>http://maven.aliyun.com/nexus/content/groups/public</url>
	</mirror>
  </mirrors>

在mirror中按照规则添加就可以，例如下面的添加aliyun镜像，有些时候国内镜像会不全。

 <mirror>
        <id>nexus-aliyun</id>
        <mirrorOf>*</mirrorOf>
        <name>Nexus aliyun</name>
        <url>http://maven.aliyun.com/nexus/content/groups/public</url>
	</mirror>
