Error downloading 'webapp-xsd-2.5' and 'maven-v4.0.0-xsd'

[SNEHAL-VATS]

I am trying to test run Java RESTEasy and Jersey projects, as a trial and have installed Apache tomcat v9 from the eclipse system itself.

I was following the tutor when i chanced upon these errors, which were not visible in others' projects.
