我正在尝试关注tutorial，但我无法让 reactivemongo 工作：

这是我的错误：

  UNRESOLVED DEPENDENCIES         ::
[warn]  ::::::::::::::::::::::::::::::::::::::::::::::
[warn]  :: org.reactivemongo#play2-reactivemongo_2.12;0.11.7.play24: not found
[warn]  ::::::::::::::::::::::::::::::::::::::::::::::

[warn]  Note: Unresolved dependencies path:

这是我的built.sbt：

name := """rest-api"""
organization := "com.example"

version := "1.0-SNAPSHOT"

lazy val root = (project in file(".")).enablePlugins(PlayScala)

scalaVersion := "2.12.4"

libraryDependencies += guice
libraryDependencies += "org.scalatestplus.play" %% "scalatestplus-play" % "3.1.2" % Test
libraryDependencies ++= Seq(
  jdbc,
  cache,
  ws,
  specs2 % Test,
  "org.reactivemongo" %% "play2-reactivemongo" % "0.11.7.play24",
  "org.scalatest" % "scalatest_2.11" % "2.2.4" % "test"
)

// Adds additional packages into Twirl
//TwirlKeys.templateImports += "com.example.controllers._"

// Adds additional packages into conf/routes
// play.sbt.routes.RoutesKeys.routesImport += "com.example.binders._"

这是我的application.conf：

# https://www.playframework.com/documentation/latest/Configuration

play.modules.enabled += "play.modules.reactivemongo.ReactiveMongoModule"

mongodb.uri = "mongodb://localhost:27017/getting-started-play-scala"

我无法让sbt run 工作。有什么想法吗？

【解决方案1】：

根据https://mvnrepository.com/artifact/org.reactivemongo/play2-reactivemongo.

reactivemongo 0.11.7.play24 所需的 scala 版本是 2.11。为 scalaVersion 尝试 0.13.0-play26 := "2.12.4" 并播放 26。

libraryDependencies += "org.reactivemongo" %% "play2-reactivemongo" % "0.13.0-play26"
