Is your feature request related to a problem? Please describe.
Currently the gradle files contain a lot of stuff which they do not need to handle indeed, such as storing the version numbers/ids, raw dependencies' names in strings. They can be cleaned up and via separating the functionalities, they'll be more readable and understandable.

Describe the solution you'd like
Conversion from groovy to kotlin scripts, so that we can use dsls to make 'em look clean.

Describe alternatives you've considered
No alternatives yet

PS: I can work on this issue if it turns out to be a valid one to project maintainers, thanks.
