scala - sbt:在编译测试时设置特定的 scalacOptions 选项

Question

通常我使用这组选项来编译 Scala 代码:

scalacOptions ++= Seq(
    "-deprecation",
    "-encoding", "UTF-8",
    "-feature",
    "-unchecked",
    "-language:higherKinds",
    "-language:implicitConversions",
    "-Xfatal-warnings",
    "-Xlint",
    "-Yinline-warnings",
    "-Yno-adapted-args",
    "-Ywarn-dead-code",
    "-Ywarn-numeric-widen",
    "-Ywarn-value-discard",
    "-Xfuture",
    "-Ywarn-unused-import"
)

但是其中一些不能很好地与 ScalaTest 配合使用，所以我想禁用 -Ywarn-dead-code和 -Ywarn-value-discard编译测试时。

我尝试添加这样的范围

scalacOptions in Compile ++= Seq(...)

或者

scalacOptions in (Compile, compile) ++= Seq(...)

甚至

val ignoredInTestScalacOptions = Set(
    "-Ywarn-dead-code",
    "-Ywarn-value-discard"
)

scalacOptions in Test ~= { defaultOptions =>
  defaultOptions filterNot ignoredInTestScalacOptions
}

但是前两个禁用正常编译范围的选项，而后者不影响测试编译选项。

编译测试时如何有单独的选项列表？

有同样的问题，@Mike Slinn 的回答对我不起作用。
我相信测试选项扩展了编译选项？
最终的诀窍是从测试中明确删除被忽略的选项
scalacOptions in Test --= Seq(
"-Ywarn-dead-code",
"-Ywarn-value-discard")
