sbt 程序集错误：重复数据删除：在 io.netty.versions.properties 中找到不同的文件内容

我已将以下罐子添加到build.sbt文件如下：

"com.amazonaws" % "aws-java-sdk" % "1.11.492"

发布此信息，在合并期间，我收到以下错误：

 [error] 1 error was encountered during merge

我已经尝试了为此提供的许多解决方法，例如：

1）添加这一行assemblyMergeStrategy in build.sbt:case PathList("io", "netty", xs @ _*) => MergeStrategy.discard（尝试过.last and .first)

2）添加这一行assemblyMergeStrategy in build.sbt:case "META-INF\\io.netty.versions.properties" =>MergeStrategy.first（尝试过.last and .discard)

3）在exclusiveDependency中为错误的netty jar添加了SBT排除规则，如下所示：

    excludeDependencies ++= Seq(
      SbtExclusionRule("io.netty", "netty-codec-http"),
      SbtExclusionRule("io.netty", "netty-codec"),
      SbtExclusionRule("io.netty", "netty-handler"),
      SbtExclusionRule("io.netty", "netty-transport"),
      SbtExclusionRule("io.netty", "netty-resolver"),
      SbtExclusionRule("io.netty", "netty-buffer"),
      SbtExclusionRule("io.netty", "netty-common")
    )

以及上述的许多此类变体。这些解决方案都不起作用。

plugins.sbt如下所示：

addSbtPlugin("io.spray" % "sbt-revolver" % "0.7.2")

addSbtPlugin("com.eed3si9n" % "sbt-buildinfo" % "0.5.0")

addSbtPlugin("com.eed3si9n" % "sbt-assembly" % "0.14.9")

addSbtPlugin("com.typesafe.sbt" % "sbt-native-packager" % "1.0.1")

addSbtPlugin("com.scalapenos" % "sbt-prompt" % "0.2.1")

addSbtPlugin("com.timushev.sbt" % "sbt-updates" % "0.1.10")

addSbtPlugin("net.virtual-void" % "sbt-dependency-graph" % "0.8.0")

addSbtPlugin("com.typesafe.sbteclipse" % "sbteclipse-plugin" % "4.0.0")

好心提醒。

您可以尝试以下操作：

assemblyMergeStrategy in assembly := {
      case x if x.contains("io.netty.versions.properties") => MergeStrategy.discard
      case x =>
        val oldStrategy = (assemblyMergeStrategy in assembly).value
        oldStrategy(x)
}

或者在最坏的情况下

case x if x.contains("versions.properties") => MergeStrategy.discard
