1. before you start to download dependencies for maven project, you should add settings.xml to your username's ".m2"folder, in order to download private packages
according to: http://www.codedata.com.tw/java/understanding-gradle-2-maven/
透過『宣告』相依性的方法在替專案增加相依函式庫，將專案原始碼與函式庫分開處理，方便了版本控制系統的使用。編譯成果會被放在 target 目錄下，除了 target 目錄的內容，其他都是需要進版本控制系統的『資料』。而函式庫會由 Maven 透過 repostiory server 下載，並 cache 在使用者目錄下的 /.m2 目錄

written those texts into your "settings.xml",and save to your user home directory's ".m2" folder
