# Gradle
Using the gradle wrapper, so the same as what we have in each branch
of Hibernate ORM.
I don't think Gradle's version matters, we just recently used version
4, then 5, now 6 and they all perform well.

# JDK
Shouldn't matter either as I have many versions installed, and from
different vendors, to run various tests. Never noticed one being
particularly slow.

# OS
I run Fedora Linux exclusively, as most members of the team. Some of
us are on OSX, some use different Linux distributions.

Very odd. Having some old style spinning drives? AFAIK we all use fast
solid state drives for development.
