如果你觉得maven下载太慢就用国内的镜像好了
找到你安装的maven下的setting.xml
我是用homeBrew下载的，所以它的路径在下面
/usr/local/Cellar/maven@3.5/3.5.4_1/libexec/conf/setting.xml
添加
<mirror>
<id>alimaven</id>
<name>aliyun maven</name>
<url>http://maven.aliyun.com/nexus/content/groups/public/</url>
<mirrorOf>central</mirrorOf>
</mirror>
到<mirrors>里
它的描述如下
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.
顺便加一下配置信息,添加到<profiles>标签
<profile>
<id>jdk‐1.8</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>
</profile>
