sbt - Scala fatal warnings but excluding deprecations flag not work

Question

According to https://alexn.org/blog/2020/05/26/scala-fatal-warnings.html

"-Wconf:cat=deprecation:ws,any:e"

Will turn warnings into errors, except for deprecations. But it gives this:

[error] bad option: '-Wconf:cat=deprecation:ws,any:e'
[error] (Compile / compileIncremental) Compilation failed

where

scalaVersion := "2.12.12"
