Scala sbt assemblyMergeStrategy 问题

Question

过去两三天我一直在尝试解决我的 sbt 程序集构建逻辑的一些问题。它与assemblyMergeStrategy 有关。 SBT 版本 1.2.8。

看起来像这样：

assemblyMergeStrategy in assembly := {
      case PathList("javax", "inject", _ @ _*) => MergeStrategy.last
      case PathList("javax", "servlet", _ @ _*) => MergeStrategy.last
      case PathList("javax", "activation", _ @ _*) => MergeStrategy.last
      case PathList("org", "apache", _ @ _*) => MergeStrategy.last
      case PathList("com", "google", _ @ _*) => MergeStrategy.last
      case PathList("com", "typesafe", _ @ _*) => MergeStrategy.last
      case PathList("com", "microsoft", xs @ _*) => MergeStrategy.last
      case "about.html" => MergeStrategy.rename
      case "plugin.properties" => MergeStrategy.last
      case "log4j.properties" => MergeStrategy.last
      case PathList("META-INF", xs @ _*) =>
        xs match {
          case "MANIFEST.MF" :: Nil => MergeStrategy.discard
          case "mailcap" :: Nil => MergeStrategy.last
          case "mimetypes.default" :: Nil => MergeStrategy.last
          // Concatenate everything in the services directory to keep GeoTools happy.
          case "services" :: _ :: Nil =>
            MergeStrategy.concat
          // Concatenate these to keep JAI happy.
          case "javax.media.jai.registryFile.jai" :: Nil | "registryFile.jai" :: Nil |
              "registryFile.jaiext" :: Nil =>
            MergeStrategy.concat
          case name :: Nil => {
            // Must exclude META-INF/*.([RD]SA|SF) to avoid "Invalid signature file digest for Manifest main attributes" exception.
            if (name.endsWith(".RSA") || name.endsWith(".DSA") || name.endsWith(".SF"))
              MergeStrategy.discard
            else
              MergeStrategy.first
          }
          case _ => MergeStrategy.first
        }
      case x =>
        val oldStrategy = (assemblyMergeStrategy in assembly).value
        oldStrategy(x)
        //MergeStrategy.first
    }

出于某种原因，我认为没有选择 com.microsoft 合并策略或类似的策略。

[error] 1 error was encountered during merge
[error] java.lang.RuntimeException: deduplicate: different file contents found in the following:

[error] /Users/t23528/.ivy2/cache/com.microsoft.azure/azure-mgmt-batchai/jars/azure-mgmt-batchai-1.23.0.jar:maven.properties

还有更多来自 Microsoft jars，都带有相同的 maven.properties 错误。

如果我将程序集的最后一部分保留为

case x =>
  //val oldStrategy = (assemblyMergeStrategy in assembly).value
  //oldStrategy(x)
  MergeStrategy.first

构建通过。知道我做错了什么吗？任何帮助将不胜感激。

我尝试升级到最新的 sbt 版本 1.3.13，看起来它正在使用其他缓存，不再是 ivy2，而是 Coursier。

谢谢。

你能试试这样的吗：

case x if x.contains("com.microsoft") => MergeStrategy.last
