如何使sbt-assembly合并正确? [英] How to get sbt-assembly merge right?

问题描述

在我们的Scala/Scalatra项目中，我们为插件sbt-assembly制定了以下合并策略:

In our Scala/Scalatra project, we have this merge policy for the plugin sbt-assembly:

assemblyMergeStrategy in assembly := {
  case x =>
   val oldStrategy = (assemblyMergeStrategy in assembly).value
   oldStrategy(x)
}

[错误]合并期间遇到11个错误 java.lang.RuntimeException:重复数据删除:在以下文件中找到不同的文件内容: 〜/.ivy2/cache/org.scalatra/scalatra_2.11/jars/scalatra_2.11-2.3.1.jar:mime.types 〜/.ivy2/cache/com.amazonaws/aws-java-sdk-s3/jars/aws-java-sdk-s3-1.10.1.jar:mime.types

并且对于不同的类名也存在相同的错误

and the same error for different class names

这里正确的合并逻辑是什么?

What would be the right merge logic here?

版本:

推荐答案

我的原始问题已通过以下方式解决:

My original issue was solved with:

assemblyMergeStrategy in assembly := {
  case PathList("org", "apache", "commons", "collections", xs @ _*) =>
      MergeStrategy.last
  case PathList("mime.types") =>
      MergeStrategy.last
  case x =>
      val oldStrategy = (assemblyMergeStrategy in assembly).value
      oldStrategy(x)
}
