Spring 5とKotlin 1.1コルーチン：タイプrx.Schedulerが存在しない

Question

私はSpringコンテキスト5.0.0.RELEASEでKotlin 1.1.4-3を使用しています。開始プロジェクトで

私はこのエラーを取得する：

春がrx.Schedulerクラスを探しているが、それはクラスパスにないようです。 rx.Schedulerの対応する依存関係は追加されていません。インターネット上の何かを見つけることはできませんでした。

プロジェクトにRxJava2（io.reactivex.rxjava2）を追加しましたが、動作しませんでした。 どうすればいいですか？

最終的な答え - ラファウG.応答に基づいて：

このエラーが原因konrad-kaminski/spring-kotlin-coroutineライブラリを使用するのです。 しかし、私は私のプロジェクトでこれらの依存関係を使用：​​

"org.springframework.kotlin" % "spring-kotlin-coroutine" % "0.2.2" exclude("org.jetbrains.kotlinx", "kotlinx-coroutines"), 

    "org.springframework" % "spring-context" % "5.0.0.RELEASE", 
    "org.springframework.data" % "spring-data-jpa" % "2.0.0.RELEASE", 

    // https://mvnrepository.com/artifact/io.reactivex.rxjava2/rxjava 
    "io.reactivex.rxjava2" % "rxjava" % "2.1.4", 

    // https://mvnrepository.com/artifact/io.reactivex/rxjava 
    "io.reactivex" % "rxjava" % "1.3.2", 

    // https://mvnrepository.com/artifact/io.projectreactor/reactor-core 
    "io.projectreactor" % "reactor-core" % "3.1.0.RELEASE" 

Answer 1

あなたはクラスrx.Schedulersが定義されている場所ですのでRxJava 1を使用する必要があります。
