Visual Builder

I have added below snippet to publish the repositories using the command
gradle publish, but I don't get any errors and it shows build successful only. When I check Visual Builder Studio UI, I don't see jar got published under Maven tab

If I don't provide credentials element or incorrrect credentials , it doesn't make any difference.

Note: I have copied the url from Visual Builder Studio UI in Maven tab

publishing {
 repositories {
   maven {
     url "http://example.com"
     credentials {
       username = "user"
       password = "pwd"
     }
     authentication {
       basic(BasicAuthentication)
     }
   }
 }
