scala - java.lang.NoSuchMethodError : play. api.Logger$.init(Ljava/io/File;Lscala/Enumeration$Value;)V

Question

我是 Scala 和 sbt 的新手。经过大量调查，我想出了下面的build.sbt。我无法为此找到解决方案。继续下去对我很有帮助。

scalaVersion := "2.11.7"

scalaVersion in ThisBuild := "2.11.7"

val sparkVersion = "1.3.0"

val akkaVersion = "2.3.6"

libraryDependencies ++= Seq(
jdbc,
cache,
"com.typesafe.play" % "play_2.11" % "2.5.0-M2",
"org.slf4j" % "jcl-over-slf4j" % "1.7.18",
"org.slf4j" % "slf4j-simple" % "1.6.2",
"com.typesafe.akka" % "akka-actor_2.11" % "2.4.2",
"com.typesafe.akka" % "akka-slf4j_2.11" % "2.4.2",
"org.webjars" % "webjars-play_2.11" % "2.4.0-2",
"com.typesafe.play" % "play-ws_2.11" % "2.5.0-M2",

"net.databinder.dispatch" % "dispatch-core_2.11" % "0.11.3",
"org.reactivemongo" % "play2-reactivemongo_2.11" % "0.11.10.play23",
"org.specs2" %% "specs2-core" % "3.6.5" % "test",
"org.specs2" %% "specs2-junit" % "3.6.5" % "test",
"org.specs2" %% "specs2-mock" % "3.6.5" % "test",
"org.mongodb" %% "casbah" % "2.8.1",                       // MongoDB Casbah
"com.sksamuel.elastic4s" %% "elastic4s" % "1.4.14"
)

编译很好，但运行时出错，我不确定错误在哪里。

错误:

Answer 1

您不能混合搭配不同的 Play 版本。

ReactiveMongo "0.11.10.play23"实际上需要Play 2.3。您尝试使用里程碑 2 Play 2.5 开发版本。

目前最新的官方 Play 版本是 2.4.6，所以不要使用目前尚未最终确定的 Play 2.5 的开发里程碑(M2)。

Play 2.4 有一个匹配的 ReactiveMongo 版本。用那个。

此外，当你想开发一个 Play 应用程序时，你应该只使用(类型安全的)lightbend“Activator”，它使用 Play SBT 插件(它具有适当的模板和路由编译支持等)生成一个适当的项目模板。
