未能用gradle构建kotlin项目

Question

克隆此项目时https://github.com/artem-zinnatullin/droidcon-nyc-2017-puzzlers.git

该项目未能建立，我得到了一个错误。这似乎是rxjava lib中的问题，但我找不到。

// 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)
}

}
