• 配置国内镜像仓库（阿里云）
  编辑M2_HOME/conf/setting.xml文件找到节点，往里面添加配置代码

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

• 配置本地仓库
  默认的缓存库 ${user.home}/.m2/repository
  如需修改，修改<localRepository>节点:

<localRepository>/Users/alexleon/Development/Environment/apache-maven-3.8.4/maven-repo</localRepository>

• 验证配置+下载基础jar包

mvn help:system
