批量将本地的maven仓库导入到nexus3中_nexus3批量导入本地仓库

前提
浏览器登录nexus管理界面–>设置图标–>Repository–>Repositories–>maven-releases–>Hosted–>请选择‘Allow redeploy’策略，(默认是disable策略，然后保存。 请注意，不同版本的nexus，进入的路径可能有细微区别)

• 依赖
   <dependency>
       <groupId>com.squareup.okhttp3</groupId>
       <artifactId>okhttp</artifactId>
       <version>3.8.1</version>
   </dependency>
   

• 代码(需要在代码中修改nexus3的请求url和base64加密的字符串)
