Ошибка помпома: неспособность найти org.springframework.boot

There might have been some intermittent Internet issue or something. 
I was facing the same problem yesterday.
Updating the the project
(On STS or Eclipse, right click on the project and Maven -> Update project 
-> tick everything except Offline) 
after sometime fixed it.
