Answer 1

This is an irritating error that pops up once in a while , jotting down some steps which help:

Writing answer from eclipse perspective as base logic will remain the same whether done by Intellij or command line

1. Rt click your project -> Maven -> Update project -> Select Force update -> Click OK
2. Under properties tag , add :

1.8 
1.8

3. In some instances, you will start seeing error as we tried force update saying , failure to transfer X dependency from Y path , resolutions will not be reattempted , bla bla bla

   In such case quickly fix it by cd to .m2/repository folder and run following command :

for /r %i in (*.lastUpdated) do del %i
