Also, there doesn't seem to be any way of defining what kind of JS module is being created. CommonJS vs umd vs anything else. If anyone has suggestions in that area, that would be great.

This is still done in the

kotlinOptions

. As of 1.3.11, those are only available in the task (you can access it by name, taking the

compileKotlinTaskName

from the compilation). In 1.3.20,

kotlinOptions

are also exposed as a member of

KotlinCompilation

(the inherited compilation types have more concrete

kotlinOptions

types).

Thanks!
