It may be late, but others might find it useful. I faced the same issue when I was trying to create a project in eclipse using Spring Starter Project.
What I did was change the Service Url from http://start.spring.io/
to https://start.spring.io/
. I just changed the http
to https
and it worked. I don't know if it is a security related error or what, but I was able to create a project.
