error

scalac: bad option: -P:opt2

My config:
RollsCompilerPlugin is a StandardPlugin

    scalacOptions ++= Seq(
      s"-P:RollsCompilerPlugin:opt1,opt2"
    )

[jxnu-liguobin]

work

-P:RollsCompilerPlugin:opt1,
-P:RollsCompilerPlugin:opt2

but compiler comment is

  def addPluginPhases(plan: List[List[Phase]])(using Context): List[List[Phase]] = {
    // plugin-specific options.
    // The user writes `-P:plugname:opt1,opt2`, but the plugin sees `List(opt1, opt2)`.
    def options(plugin: Plugin): List[String] = {
      def namec = plugin.name + ":"
      ctx.settings.pluginOptions.value filter (_ startsWith namec) map (_ stripPrefix namec)
    }

😅

Hey @jxnu-liguobin, thanks for reporting this and sorry this has sat here for such a long time. This does indeed seem to be a mismatch between what the comment says and what we have in the code. I've created #17448 to either address this or get some clarity.
