用maven時出現，報錯 miss 一些包，可是發現項目裏已經引入了，但仍是報錯

引用一個解決方法：

解決方法： If you are using Eclipse, Right Click on your Project -> Maven -> Update Project. It will open Update Maven Project dialog box.

In that dialog box, check Force Update of Snapshots/Releases checkbox & click OK. (Please refer image below)

Update Maven Project Dialog Box

This worked for me !
