We're transitioning to Kotlin. And our main problem with it is slow compilation.
With only Java is was <2mins and we're touching 10mins now.
I'm not sure what exactly the problem is as we still have to investigate. Our use of Kotlinx.html (which we absolutely LOVE as HTML templating tech) seems to be a part of the problem, but we have not gone to the bottom of it yet.
Nothing against the language, everyone on the team loves it (when Java is what we consider normal). The extra type safety we get out-of-the-box or have put some effort into (using KFunction all over the place) is really paying off.
