A modern programming language that makes developers happier.

kotlinlang

I am trying to introduce Kotlin into existing project and I am experiencing considerable increase in compilation time. Even if I am just rebuilding the project without any changes in pure Java it’s just a couple of seconds, but in Kotlin it takes full 2 minutes. Same if I am running particular class with test cases. With Java it’s a matter of 10-20 seconds and with Kotlin - around a minute. Any suggestions or known bottlenecks?
