Currently maven central repo is not accepting HTTP requests anymore and have fully switched to HTTPS. This has been addressed in this commit: https://github.com/apache/cassandra/commit/63ff65a8dd3a31e500ae5ec6232f1f9eade6fa3d
However `maven-ant-tasks` has been deprecated and is still fetching dependencies using HTTP, which fails when trying to publish the Cassandra jar. Basically, an alternative solution to `maven-ant-tasks` needs to be implemented for deployment.
I have attached the log from running `ant publish`.
