批量將本地的maven倉庫導入到nexus3中

批量將本地的maven倉庫導入到nexus3中

• 前提
  瀏覽器登錄nexus管理界面–>設置圖標–>Repository–>Repositories–>maven-releases–>Hosted–>請選擇‘Allow redeploy’策略，(默認是disable策略，然后保存。 請注意，不同版本的nexus，進入的路徑可能有細微區別)

  

• 依賴

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

• 代碼(需要在代碼中修改nexus3的請求url和base64加密的字符串)
