没有用gradle建立kotlin项目

克隆这个项目时https://github.com/artem-zinnatullin/droidcon-nyc-2017-puzzlers.git

该项目未能建立，我得到一个错误。 这似乎是rxjava库中的问题，但我找不到。

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) } 

}
