Just ran into the same issue, according to sbt doc (
https://github.com/sbt/sbt-assembly#merge-strategy) you can specify merge
strategies for packages in sbt-assembly like that
assemblyMergeStrategy in assembly := {
case PathList("javax", "servlet", xs @ _*) => MergeStrategy.first
case PathList(ps @ _*) if ps.last endsWith ".html" => MergeStrategy.first
case "application.conf" => MergeStrategy.concat
case "unwanted.txt" => MergeStrategy.discard
case x =>
val oldStrategy = (assemblyMergeStrategy in assembly).value
oldStrategy(x)
}
So you can use MergeStrategy.first for leveldb
