scala - sbt-assembly 排除 dependsOn 依赖

Question

我有一个包含几个子项目和许多依赖项的项目，一个子项目将进行大部分开发(应用程序)并且生成完整的 jar 需要时间。所以我想将 fat-jar 生成分成 2 个 jar :

• deps 一个 fat-jar
• 应用精益 jar

我希望创建一个像这样的 deps 项目:

lazy val deps = (project in file("deps"))
 .settings(
   libraryDependencies ++= commonDependencies,
   assemblyJarName in assembly := "deps.jar",
   assemblyMergeStrategy in assembly := {
     case m if m.toLowerCase.endsWith("manifest.mf") => MergeStrategy.discard
     case m if m.toLowerCase.matches("meta-inf.*\\.sf$") => MergeStrategy.discard
     case m if m.toLowerCase.startsWith("meta-inf/services/") => MergeStrategy.filterDistinctLines
     case m if m.toLowerCase.endsWith(".dct") => MergeStrategy.first
     case "reference.conf" => MergeStrategy.concat
     case _ => MergeStrategy.first
   }
).dependsOn(
   measurement,
   streaming,
   domain
)

我的应用项目如下:

lazy val app = (project in file("my-app"))
  .settings(clientEventSettings)
  .settings(noPublishSettings)
  .settings(
    assemblyJarName in assembly := "my-app.jar",
    assemblyMergeStrategy in assembly := {
      case m if m.toLowerCase.endsWith("manifest.mf") => MergeStrategy.discard
      case m if m.toLowerCase.matches("meta-inf.*\\.sf$") => MergeStrategy.discard
      case m if m.toLowerCase.startsWith("meta-inf/services/") => MergeStrategy.filterDistinctLines
      case m if m.toLowerCase.endsWith(".dct") => MergeStrategy.first
      case "reference.conf" => MergeStrategy.concat
      case _ => MergeStrategy.first
    })
  .dependsOn(  //<- but do not package??
    measurement,
    streaming,
    messagingDomain,
    messagingKafkaToolkit,
    domain,
    analyticsWebtrekk,
    commons
  )

编译明智的 my-app 项目依赖于其他子项目 (deps)，但它应该在 provided 范围内，因为我不希望它被 sbt-assembly 打包。

我将尝试使用 libraryDependencies，但我认为这意味着克隆 commonDependencies，所有这些都在 provided 范围内。

readme sbt-assembly 提供了答案:在部分中:Splitting your project and deps JARs

assemblyOption in assembly := (assemblyOption in assembly).value.copy(includeScala = false, includeDependency = false)
