IdeaMaven换源(保姆级别演示)

（1）在Idea中找到settings这个按钮，然后点击进去，如下图所示。

（2）然后在里面找到Buuild,Execution,Deployment,按钮

（3）点击里面的Build Tools找到Maven，将User settings file这个框后面的Override勾选上

（4）点击OK

（5）再在这个User settings file里面的路径.m下现新建先新建一个文本文档，命名为settingts.xml文件。注意：一开始，这个目录下面只有Repository这个文件夹

然后利用Idea打开这个文件，在里面写入以下的配置文件代码

<?xml version="1.0" encoding="UTF-8"?>

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"

          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">

    <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>alimaven</id>

            <name>aliyun maven</name>

            <url>http://maven.aliyun.com/nexus/content/groups/public/</url>

            <mirrorOf>central</mirrorOf>

        </mirror>

        <mirror>

            <id>uk</id>

            <mirrorOf>central</mirrorOf>

            <name>Human Readable Name for this Mirror.</name>

            <url>http://uk.maven.org/maven2/</url>

        </mirror>

        <mirror>

            <id>CN</id>

            <name>OSChina Central</name>

            <url>http://maven.oschina.net/content/groups/public/</url>

            <mirrorOf>central</mirrorOf>

        </mirror>

        <mirror>

            <id>nexus</id>

            <name>internal nexus repository</name>

            <!-- <url>http://192.168.1.100:8081/nexus/content/groups/public/</url>-->

            <url>http://repo.maven.apache.org/maven2</url>

            <mirrorOf>central</mirrorOf>

        </mirror>

    </mirrors>

</settings>

至此换源完成。
