只是想用 sbt-assembly 生成一个 Jar，我仍然被这个困住了：

[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-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)
  }
}

仍然没有喜悦，几乎尝试了一切。

PathList(...)提取器拆分路径字符串。以下应该有效：

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

您是否尝试过更简单的：

mergeStrategy in assembly := mergeStrategy.first

更新，不要这样，请看评论
