网上配置maven国内镜像的文章很多，为什么选择我，原因是：一次配置得永生、仓库覆盖广、仓库覆盖全面、作者自用的配置。

1. 配置maven的settings.xml文件

1.1. 先把镜像mirror配置好

复制就完事了

<mirrors>
	<mirror>
      <id>aliyun-central</id>
      <!-- 一定不能用*，否则所有的都会被拦截，哪怕在这个仓库找不到依赖 -->
      <mirrorOf>central</mirrorOf>
      <name>aliyun central</name>
      <url>https://maven.aliyun.com/repository/central</url>
    </mirror>

    <mirror>
        <id>repo1</id>
        <mirrorOf>central</mirrorOf>
        <name>Human Readable Name for this Mirror.</name>
        <url>http://repo1.maven.org/maven2/</url>
    </mirror>

    <mirror>
        <id>repo2</id>
        <mirrorOf>central</mirrorOf>
        <name>Human Readable Name for this Mirror.</name>
        <url>http://repo2.maven.org/maven2/</url>
    </mirror>
</mirrors>

1.2. 再把仓库配置好

复制就完事了

    <profile>
      <!-- 默认的项目编译环境 -->
      <id>jdk1.8</id>
      <activation>
        <activeByDefault>true</activeByDefault>
        <jdk>1.8</jdk>
      </activation>
      <properties>
        <maven.compiler.source>1.8</maven.compiler.source>
        <maven.compiler.target>1.8</maven.compiler.target>
        <maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion>
      </properties>


      <!-- 所有的镜像仓库 -->

2. 在idea中引用

如下图在框框处引用你自己的maven本地地址，点击应用点击OK。然后重新刷新您的maven项目看看是不是在下载jar包。

idea不自动生成target
