Błąd podczas instalacji sbt - deduplikacja: inna zawartość pliku znajduje się poniżej:

Question

Otrzymuję następujący błąd podczas wykonywania ./sbt assembly w moim projekcie Scala. Widziałem pierwszy po dodaniu tych zależności do mojego build.sbt Mogę skompilować i uruchomić mój kod.

libraryDependencies ++= Seq(
    "org.scalanlp" % "breeze_2.10" % "0.7", 
    "org.scalanlp" % "breeze-natives_2.10" % "0.7" 
)

Answer 1

Używam tego w moim build.sbt:

excludedJars in assembly <<= (fullClasspath in assembly) map { cp => 
cp filter {x => x.data.getName.matches("sbt.*") || x.data.getName.matches(".*macros.*")} 
} 

Answer 2

samą odpowiedź jak @dlwh ale ponieważ excludedJars jest przestarzała, użycie assemblyExcludedJars zamiast

Answer 3

while referening to this Doc dodałem poniżej urywek w moim projekcie co sprawia, że ​​pracuję dla mnie

assemblyMergeStrategy w złożeniu: = {
przypadku pathlist ("meta-INF" XS @ _ *) => MergeStrategy.discard
przypadku gdy X => MergeStrategy.first

}

w pliku build.sbt
