failed to build kotlin project with gradle - gradle

Question

When cloning this project https://github.com/artem-zinnatullin/droidcon-nyc-2017-puzzlers.git
The project failed to build and I got an error.
It seems like the problem in rxjava lib but i cannot find out.
class MediumRxPuzzler2 {
// What will be printed and why?
#Test
fun puzzler() {
val observer = object : Observer<Int> {
override fun onSubscribe(d: Disposable) = Unit
override fun onNext(t: Int) {
println("onNext $t")
}
override fun onComplete() {
println("onComplete")
}
override fun onError(e: Throwable) {
println("onError $e")
}
}
Observable.just(1).subscribe(observer)
Observable.just(2).subscribe(observer)
}
// What will be printed and why?
#Test
fun `same puzzler?`() {
val observer = object : DefaultObserver<Int>() {
override fun onNext(t: Int) {
println("onNext $t")
}
override fun onComplete() {
println("onComplete")
}
override fun onError(e: Throwable) {
println("onError $e")
}
}
Observable.just(1).subscribe(observer)
Observable.just(2).subscribe(observer)
}
}
