scalacOption "-P:acyclic:force" does not work for scala 3

[sven42]

Hello,

I am using scala 3.7.4 and mill 1.0.6.

Using this configuration:

  def compileIvyDeps      = Seq(mvn"com.lihaoyi:::acyclic:0.3.20")
  def scalacPluginIvyDeps = Seq(mvn"com.lihaoyi:::acyclic:0.3.20")

  override def scalacOptions = Seq("-P:acyclic:force")

Causes this error:
[error] bad option: -P:acyclic:force

I found in the mill codebase that this option only used when not using scala 3. So this seems to be known, but undocumented.

Best regards,
Sven
