Thank you both for your answers. I will try out the channel and see if I can figure something out :)
I don’t have that much computing power with my little i3, I'm sure it will manage lol. I suppose once kotlin is built I won't have to build it again, unless it is itself packaged with gradle 😵💫. I'll keep you updated once I make some progress, in the meanwhile we can probably close this issue. All the best, Noé
