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 --><repositories><repository><id>aliyun-public</id><name>aliyun public</name><url>https://maven.aliyun.com/repository/public</url><releases><enabled>true</enabled></releases><snapshots><enabled>true</enabled></snapshots></repository><repository><id>aliyun-spring</id><name>aliyun spring</name><url>https://maven.aliyun.com/repository/spring</url><releases><enabled>true</enabled></releases><snapshots><enabled>true</enabled></snapshots></repository><repository><id>aliyun-spring-plugin</id><name>aliyun spring-plugin</name><url>https://maven.aliyun.com/repository/spring-plugin</url><releases><enabled>true</enabled></releases><snapshots><enabled>true</enabled></snapshots></repository><repository><id>aliyun-apache-snapshots</id><name>aliyun apache-snapshots</name><url>https://maven.aliyun.com/repository/apache-snapshots</url><releases><enabled>true</enabled></releases><snapshots><enabled>true</enabled></snapshots></repository><repository><id>aliyun-google</id><name>aliyun google</name><url>https://maven.aliyun.com/repository/google</url><releases><enabled>true</enabled></releases><snapshots><enabled>true</enabled></snapshots></repository><repository><id>aliyun-gradle-plugin</id><name>aliyun gradle-plugin</name><url>https://maven.aliyun.com/repository/gradle-plugin</url><releases><enabled>true</enabled></releases><snapshots><enabled>true</enabled></snapshots></repository><repository><id>aliyun-jcenter</id><name>aliyun jcenter</name><url>https://maven.aliyun.com/repository/jcenter</url><releases><enabled>true</enabled></releases><snapshots><enabled>true</enabled></snapshots></repository><repository><id>aliyun-releases</id><name>aliyun releases</name><url>https://maven.aliyun.com/repository/releases</url><releases><enabled>true</enabled></releases><snapshots><enabled>true</enabled></snapshots></repository><repository><id>aliyun-snapshots</id><name>aliyun snapshots</name><url>https://maven.aliyun.com/repository/snapshots</url><releases><enabled>true</enabled></releases><snapshots><enabled>true</enabled></snapshots></repository><repository><id>aliyun-grails-core</id><name>aliyun grails-core</name><url>https://maven.aliyun.com/repository/grails-core</url><releases><enabled>true</enabled></releases><snapshots><enabled>true</enabled></snapshots></repository><repository><id>aliyun-mapr-public</id><name>aliyun mapr-public</name><url>https://maven.aliyun.com/repository/mapr-public</url><releases><enabled>true</enabled></releases><snapshots><enabled>true</enabled></snapshots></repository></repositories></profile>

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。

3. 参考资料

idea不自动生成target
