Consider using a different build system

[adamw]

With same features as we have now: building core, JMH fat-jars, releasing to sonatype

In the mean time may I suggest using the maven wrapper? It means that people can build the project with the "right" version of maven without needing to figure out which one is it and without having to install it.

Adding it is as easy as running

mvn wrapper:wrapper

and adding the files this created to git.
