scala - 错误:java.lang.NoSuchMethodError:com.google.common.util.concurrent.MoreExecutors.directExecutor()Ljava/util/concurrent/Executor;

Question

我得到错误，就像标题一样。我已经在研究，并且发现了一些类似的东西，但是对我不起作用。

NoSuchMethodError: com.google.common.util.concurrent.MoreExecutors.directExecutor conflits on Elastic Search jar

Java elasticsearch client always null

https://github.com/elastic/elasticsearch/pull/7593

java.lang.NoSuchMethodError during Elastic search start

https://discuss.elastic.co/t/transportclient-in-2-1-x/38818/6

我使用Scala作为创建API的编程语言，并使用Elasticsearch作为数据库。

这是我的代码 build.sbt

name := "LearningByDoing"

version := "1.0"

scalaVersion := "2.10.5"

resolvers += "spray repo" at "http://repo.spray.io"
resolvers += "spray nightlies repo" at "http://nightlies.spray.io"

libraryDependencies += "io.spray" % "spray-json_2.10" % "1.3.2"
libraryDependencies += "io.spray" % "spray-can_2.10" % "1.3.2"
libraryDependencies += "io.spray" % "spray-client_2.10" % "1.3.2"
libraryDependencies += "io.spray" % "spray-testkit_2.10" % "1.3.2"
libraryDependencies += "io.spray" % "spray-routing_2.10" % "1.3.2"
libraryDependencies += "io.spray" % "spray-http_2.10" % "1.3.2"
libraryDependencies += "io.spray" % "spray-httpx_2.10" % "1.3.2"
libraryDependencies += "io.spray" % "spray-util_2.10" % "1.3.2"
libraryDependencies += "io.spray" % "spray-can_2.10" % "1.3.2"

libraryDependencies += "mysql" % "mysql-connector-java" % "5.1.12"
libraryDependencies += "org.elasticsearch" % "elasticsearch" % "2.3.1"
libraryDependencies += "com.sksamuel.elastic4s" % "elastic4s-streams_2.10" % "2.3.1"
libraryDependencies += "org.elasticsearch" % "elasticsearch-mapper-attachments" % "2.3.1"
libraryDependencies += "com.typesafe" % "config" % "1.2.1"
libraryDependencies += "com.typesafe.akka" % "akka-actor_2.10" % "2.3.1"

这是我的代码 plugins.sbt

addSbtPlugin("com.eed3si9n" % "sbt-assembly" % "0.13.0")
addSbtPlugin("com.typesafe.sbt" % "sbt-native-packager" % "1.0.0-M4") 
addSbtPlugin("com.typesafe.sbt" % "sbt-multi-jvm" % "0.3.9")
addSbtPlugin("org.scalastyle" %% "scalastyle-sbt-plugin" % "0.8.0")

在终端上，我被写成 sbt clean编译测试更新包，一切正常。但是当我点击API时，总会出现这样的错误。

好像您使用了错误的 Guava 版本，就像您提到的firs link一样，可能是使用this sbt插件，您可以看到依赖关系树并弄清楚了一些混乱的依赖关系。
