Akka Testkit 错误且版本不明确

我正在使用 Akka testkit 库来测试我的一些演员。

这是我的 build.sbt 中的内容：

"com.typesafe.akka" %% "akka-testkit" % "2.6.10" % Test,

这是我得到的错误：

java.lang.IllegalStateException: You are using version 2.6.10 of Akka, but it appears you (perhaps indirectly) also depend on older versions of related artifacts. You can solve this by adding an explicit dependency on version 2.6.10 of the [akka-actor-typed, akka-slf4j, akka-protobuf-v3, akka-stream, akka-serialization-jackson] artifacts to your project. See also: https://doc.akka.io/docs/akka/current/common/binary-compatibility-rules.html#mixed-versioning-is-not-allowed

我很困惑，因为我对 Akka 没有任何其他依赖项，因为这里是我的 build.sbt 中定义的所有依赖项：

libraryDependencies ++= Seq(
  ws,
  // Our streaming library
  "io.monix" %% "monix" % "3.3.0",

  // Dependencies needed for Slick
  "com.typesafe.slick" %% "slick" % "3.3.3",
  "com.typesafe.slick" %% "slick-hikaricp" % "3.3.3",

  // For application Metrics
  "io.dropwizard.metrics" % "metrics-core" % "4.1.16",
  "io.dropwizard.metrics" % "metrics-jvm" % "4.1.16",
  "com.typesafe.scala-logging" %% "scala-logging" % "3.9.2",
  "org.scala-lang.modules" % "scala-async_2.11" % "0.9.7",
  "com.typesafe" % "config" % "1.4.1",

  // For JSON parsing
  "com.typesafe.play" %% "play-json" % "2.9.1",
  "com.typesafe.play" %% "play-json-joda" % "2.9.1",

  // JDBC driver for MySQL & H2
  "mysql" % "mysql-connector-java" % "8.0.22",
  "com.h2database" % "h2" % "1.4.186",

  // Test dependencies
  "com.typesafe.akka" %% "akka-testkit" % "2.6.10" % Test,
  "org.scalatest" %% "scalatest" % "3.2.3" % Test,
  "org.awaitility" % "awaitility" % "4.0.3" % Test,
  "org.scalatestplus.play" %% "scalatestplus-play" % "5.1.0" % Test exclude ("org.slf4j", "slf4j-simple"),
  "com.github.andyglow" %% "websocket-scala-client" % "0.3.0" % Test exclude ("org.slf4j", "slf4j-simple")
)

有什么想法如何解决这个问题吗？

所以我必须为 Akka 添加一些依赖项，如下所示：

  "com.typesafe.akka" %% "akka-testkit" % AkkaVersion % Test,
  "com.typesafe.akka" %% "akka-slf4j" % AkkaVersion % Test,
  "com.typesafe.akka" %% "akka-protobuf-v3" % AkkaVersion % Test,
  "com.typesafe.akka" %% "akka-serialization-jackson" % AkkaVersion % Test,
  "com.typesafe.akka" %% "akka-stream" % AkkaVersion % Test,
  "com.typesafe.akka" %% "akka-actor-typed" % AkkaVersion % Test,

在我的例子中，AkkaVersion 是 2.6.10

不得不提及这些依赖项看起来很难看，但这就是我能够摆脱错误的方法。
