A modern programming language that makes developers happier.

kotlinlang

Have a look at build.gradle and update ext.kotlin_version = '1.1.4-3' to the required version.

adding `-3` worked a treat, thanks. As you said, not obvious (not to me anyway)

Any ideas about `Error:(5, 39) Kotlin: This declaration is only available since Kotlin 1.1 and cannot be used with the specified API version 1.0`

looks like I’m using 1.1 so I don’t see the problem

relates to the statement `import kotlin.coroutines.experimental.EmptyCoroutineContext.plus`

:point_up: Ignore me … got past that one
