-------------------------------------------

Since there is nothing critical blocked on this, I'll be looking to it in background based on available time.

> h2. Overview
> Cassandra relies onto {{ant}} build tool which is used there for a long time. Even though it is pretty stable, reliable and well-document, {{ant}} is not being actively developed. Releases are rare and new features/fixes appear rarely. For example, JUnit 5 support was implemented in Sep 2019 whereas the JUnit 5 itself was released in 2017.
> Moreover, ant seems to be morally obsolete:
>  * no-one (?) starts new projects with {{ant}}
>  * less and less people have hands-on experience with the tool
> h2. Goals
> The aim of this ticket is to explore two alternatives for the project: Maven, Gradle. Most of the community seem to prefer Maven at this stage, but I'd like us to be unbiased and make a fair comparison. The points to pay attention to:
>  * build speed
>  * support of necessary plugins (without ugly workarounds)
>  * IDE integration (will need to get feedback from the community)
>  * ability to improve tests speed (including both multi-threading and parallelization on multiple servers)
> h2. Steps
>  # mimic the existing build via Gradle
>  # mimic the existing build via Maven
>  # make speed comparison
>  # ask community to test IDE integration and try to address existing concerns
>  # check ability to parallelize tests
>  # make a conclusion / vote
>  # update necessary project documentation
>  # migrate trunk (not yet sure regarding older branches, but probably them too) to the new build tool 
>  
> The description is preliminary. We may update it in the future once we have more details.
