我关注了 stackoverflow 中的其他 sbt 程序集合并问题并添加了合并策略，但仍然没有得到解决。我添加了依赖树插件，但它没有显示传递库的依赖性。我已经使用了 sbt 的最新合并策略，但这个重复内容问题仍然存在。

最佳答案
我按照 sbt 文档尝试了合并策略，我认为它仍然会留下一些重复源错误，所以从其他 stakoverflow 问题中找到按照以下策略丢弃每个重复的 meta-inf。
assemblyMergeStrategy in assembly := {
case PathList("META-INF", xs @ _*) => MergeStrategy.discard
case x => MergeStrategy.first
}
关于scala - sbt 程序集合并问题 [去重 : different file contents found in the following]，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/49992899/
