我已经跟踪了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，但仍然会出现这个重复的内容问题。

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的源错误，所以从其他stakoverflow问题中找到丢弃每个重复的meta-inf，如下面的策略。
assemblyMergeStrategy in assembly := {
case PathList("META-INF", xs @ _*) => MergeStrategy.discard
case x => MergeStrategy.first
}
