Thanks guys,finally found answer to my question here More than one fragment with the name [spring_web] was found. This is not legal with relative ordering ... i had to add <absolute-ordering /> tag to my web.xml just under the <display-name> tag,now working fine.

Possible error :

One of the jar dependencies/files that your project is using seems to be corrupted.

Solution :

so to fix this error you could try deleting all your local maven repo folder,by going to following path or if you could manage to know which is the corrupted one and just delete it.

on Windows :

C://Users/{user-name}/.m2/repository/

on linux :

~/.m2

then try to update maven dependencies and it should start working

cmd to update your mvn repo

mvn dependency:resolve

i cant locate the .m2/repository/,i must note that i am following up with a tutorial and maven is yet to be covered,the jar files was copied and paste – Timi Cruz May 26 '20 at 09:20
what are you using ? windows or mac ? – ZINE Mahmoud May 26 '20 at 09:22
I am using windows – Timi Cruz May 26 '20 at 09:30
are you sure that you didn't find that .m2 on your `C:/Users/{user-name}` ? did your replaced {user-name} with your Current username on windows ? – ZINE Mahmoud May 26 '20 at 10:08
