sbt:在编译测试时设置特定的 scalacOptions 选项 [英] sbt: set specific scalacOptions options when compiling tests

问题描述

通常我使用这组选项来编译 Scala 代码:

Normally I use this set of options for compiling Scala code:

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，所以我想在编译时禁用 -Ywarn-dead-code 和 -Ywarn-value-discard测试.

But some of them don't play well with ScalaTest, so I would like to disable -Ywarn-dead-code and -Ywarn-value-discard when compiling tests.

我尝试添加这样的范围

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

或

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

甚至

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

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

但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.

but the first two disable options for normal compile scope as well while the latter doesn't affect tests compilation options.

如何在编译测试时有一个单独的选项列表?

How could I have a separate list of options when compiling tests?

推荐答案

遇到了同样的问题，@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

Had the same issue, @Mike Slinn answer didn't work for me. I believe the test options extend the compile options? What eventually did the trick was explicitly removing ignored options from test

scalacOptions in Test --= Seq("-Ywarn-dead-code","-Ywarn-value-discard")
