I am trying to create an executable jar using SBT assembly plugin.
I am ending up with below error :
[error] (app/*:assembly) deduplicate: different file contents found in the following:

After reading wikis of assembly plugin, i have added merge strategy in build.scala file. Seems it is not working. I am not sure whether it is right fix or not. Can someone suggest me the right strategy.
Below is the code which i have in build.scala file :
mergeStrategy in assembly <<= (mergeStrategy in assembly) {
(old) => {
case "about.html" => MergeStrategy.discard
case "logback.xml" => MergeStrategy.first //case PathList("logback.xml") => MergeStrategy.discard
case x => old(x)
}
}
I have coded plugin integration with my app as per this doc : Standalone deployment of Scalatra servlet
I tried diffrent strategies like MergeStrategy.rename and MergeStrategy.deduplicate. But nothing works.. Looking for help...
Your MergeStrategy looks correct. The only unhandled conflicts are "about.html" in the jetty jars, so case "about.html" => MergeStrategy.discard should just do it.
If you're still getting the error, I suspect that re-wiring of the mergeStrategy in assembly setting is either not going in, or going in the wrong order. The only way to know for sure is to see your Build.scala. @Stefan Ollinger's answer to your linked question for example sets up the project as follows:
lazy val project = Project("myProj", file(".")).
settings(mySettings: _*).
settings(myAssemblySettings:_*)
Could you post your Build.scala on gist if possible?
