sbt 程序集重复数据删除：在以下内容中找到不同的文件内容：jackson-annotations

Question

拥有这些部门：

libraryDependencies ++= Seq(
  "com.typesafe.akka" %% "akka-http-spray-json" % akkaHttpVersion,
  "com.typesafe.akka" %% "akka-stream" % akkaVersion,
  "com.typesafe.akka" %% "akka-http" % akkaHttpVersion,
  "com.typesafe.akka" %% "akka-actor-typed" % akkaVersion,
  "com.typesafe.akka" %% "akka-stream" % akkaVersion,
  "com.lightbend.akka" %% "akka-stream-alpakka-json-streaming" % akkaJsonStreaming,
  "io.circe" %% "circe-generic-extras" % circeVersion,
  "de.heikoseeberger" %% "akka-http-circe" % akkaHttpCirce,
  "commons-codec" % "commons-codec" % commonsCodecVersion,
  "org.scalatest" %% "scalatest" % scalaTestVersion % "it, test",
)

当我运行时sbt assembly出现错误：

[error] (assembly) deduplicate: different file contents found in the following:
[error] /home/baku/.cache/coursier/v1/https/repo1.maven.org/maven2/com/fasterxml/jackson/core/jackson-annotations/2.10.5/jackson-annotations-2.10.5.jar:module-info.class
[error] /home/baku/.cache/coursier/v1/https/repo1.maven.org/maven2/com/fasterxml/jackson/core/jackson-core/2.10.5/jackson-core-2.10.5.jar:module-info.class

知道如何解决这个问题吗？

Answer 1

assemblyMergeStrategy in assembly := {
      case "module-info.class" => MergeStrategy.discard
      case x =>
        val oldStrategy = (assemblyMergeStrategy in assembly).value
        oldStrategy(x)
    }

这有帮助

Answer 2

与 @FrancMo 的答案相同，但从 2022 年起更新为 SBT 语法：

    assembly / assemblyMergeStrategy := {
      case "module-info.class" => MergeStrategy.discard
      case x =>
        val oldStrategy = (assembly / assemblyMergeStrategy).value
        oldStrategy(x)
    }
