Description:

Cannot determine embedded database driver class for database type NONE

Action:

If you want an embedded database please put a supported one on the classpath. If you have database settings to be loaded from a particular profile you may need to active it (no profiles are currently active).
			
			
		

背景：Maven 項目中並不包含任何與資料庫有關的依賴。問題出在另一個公共包中如： common-version.jar

解決方案：排除不需要的包
