Когда я запускаю свои тесты, я вижу следующую ошибку:
Exception: java.lang.NoSuchMethodError: fs2.Stream$.bracket(Ljava/lang/Object;Lscala/Function1;Lscala/Function1;)Lfs2/internal/FreeC;
Сначала я удостоверился, что мой файл сборки был очищен с помощью , явно объявив транзитивные зависимости и удалив неиспользуемые зависимости для создания следующего build.sbt:
scalaVersion := "2.12.7"
organization := "com.example "
lazy val lambdas = (project in file("."))
.settings(
libraryDependencies += "org.typelevel" %% "cats-core" % "1.4.0",

)
Все компилируется, и один из моих двух тестов проходит.Другой сбой с ошибкой выше.Вот вывод sbt evicted:

При использовании sbt-dependency-graph похоже, что мне законно понадобятся две версии ядра fs2: 1.0.0 и 0.10.0.
Это моя попытка использовать затенение sbt-Assembly для обработки выселений путем переименования старой версии fs2 в библиотеке http4s, которая в этом нуждается.На самом деле ничего не компилируется с этим файлом сборки, поэтому я предполагаю, что с настройками у меня есть несколько проблем.
