Thanks for helping me.. I'm beginner

Try clearing your local cache and re-downloading. See here - https://stackoverflow.com/questions/7408545/how-do-you-clear-apache-mavens-cache — Sam, May 30 '17 at 09:08
Try running the following maven commands -> maven clean install -U, or move the specific package out of the .m2/repository folder — MrSanchez, May 30 '17 at 16:43

Kindly delete your local .m2 folder located at /Users//.m2 and try to build again.

There is no need to delete the entire local repository in order to fix this problem. Typically you would execute a command line maven build with the `-U` option to make make maven look for the artefacts again. – Steve C May 30 '17 at 09:20
