SBT-Assembly（Scala-Neo4j），如何处理此重复数据消除问题？

只是尝试用sbt组件生成一个Jar，我仍然被这个问题困扰：

[error] (*:assembly) deduplicate: different file contents found in the following:
[error] /Users/fsalvador/.ivy2/cache/org.neo4j/neo4j-kernel/jars/neo4j-kernel-1.9.4.jar:META-INF/CHANGES.txt
[error] /Users/fsalvador/.ivy2/cache/org.neo4j/neo4j-lucene-index/jars/neo4j-lucene-index-1.9.4.jar:META-INF/CHANGES.txt
[error] /Users/fsalvador/.ivy2/cache/org.neo4j/neo4j-graph-algo/jars/neo4j-graph-algo-1.9.4.jar:META-INF/CHANGES.txt
[error] /Users/fsalvador/.ivy2/cache/org.neo4j/neo4j-udc/jars/neo4j-udc-1.9.4.jar:META-INF/CHANGES.txt

[error] /Users/fsalvador/.ivy2/cache/org.neo4j/neo4j-jmx/jars/neo4j-jmx-1.9.4.jar:META-INF/CHANGES.txt

在我的build.sbt中，我尝试了以下方法：

mergeStrategy in assembly <<= (mergeStrategy in assembly) { (old) => {
    case PathList("ivy2", "cache",  "org.neo4j", xs @ _*) => MergeStrategy.last
    case "CHANGES.txt"     => MergeStrategy.discard
    case x => old(x)
  }
}

程序集mergeStrategy.last中的

mergeStrategy
案例“CHANGES.txt”=>MergeStrategy.discard
案例x=>旧（x）
}
}

还是没有乐趣，几乎什么都试过。

你试过更简单的方法吗：

mergeStrategy in assembly := mergeStrategy.first

更新，不要这样做，请查看注释

路径列表（…）

提取器拆分路径字符串。以下方面应起作用：

mergeStrategy in assembly <<= (mergeStrategy in assembly) { (old) => {
    case PathList("META-INF", "CHANGES.txt") => MergeStrategy.discard
    case x => old(x)
  }
}

程序集mergeStrategy.discard中的

mergeStrategy
案例x=>旧（x）
}
}

我特别写了一篇文章，在汇编中不做

mergeStrategy:=mergeStrategy。首先，因为它是错误的类型，而且当你跳过使jar正常工作所必需的默认策略时，你会非常痛苦。k，我想我看起来不是很努力。：）不确定是删除这个还是留给后代。我会说删除它，如果你有新的答案，就发布一个新的答案。
