错误选项:“-yliteral类型”sbt

我在斯卡拉以下 build.sbt 文件。

scalaVersion := "2.12.8"

val ccompileOptions = Seq(
  "-unchecked",
  "-deprecation",
  "-language:_",
  "-encoding", "UTF-8",
  "-Ypartial-unification",
  "-Xfatal-warnings",
  "-Yliteral-types",
  "-language:higherKinds"
)

scalacOptions ++= ccompileOptions

enablePlugins(TutPlugin)

tutTargetDirectory := baseDirectory.value

resolvers += Resolver.bintrayRepo("ovotech", "maven")

libraryDependencies ++= Seq(
  "is.cir" %% "ciris-cats",
  "is.cir" %% "ciris-cats-effect",
  "is.cir" %% "ciris-core",
  "is.cir" %% "ciris-enumeratum",
  "is.cir" %% "ciris-refined"
).map(_ % "0.12.1")

libraryDependencies ++= Seq(
  "org.http4s" %% "http4s-dsl",
  "org.http4s" %% "http4s-blaze-server"
).map(_ % "0.19.0")

libraryDependencies ++= Seq(
  "com.ovoenergy" %% "ciris-kubernetes" % "0.5" ,
  "org.typelevel" %% "kittens" % "1.2.0",
  "eu.timepit" %% "refined-cats" % "0.9.3"
)

该项目可在Github找到 here . 只需要更新scaleaversion到 2.12.8 并对此发表评论 section .

如果我删除 scalaVersion := "2.12.8" 然后添加以下内容,编译成功。

inThisBuild {
  Seq(
    scalaOrganization := "org.typelevel",
    scalaVersion := "2.12.4-bin-typelevel-4"
  )
}

当我谷歌搜索时,看起来像 -Yliteral-types 根据此从scala中删除选项 issue .

但是我创建了一个项目 scala version 2.12.8 用那个 -字形类型 启用标志 here 而且工作正常。
