changing settings in sbt task

I'm trying to defined custom task in sbt that will run main class in debug mode.

lazy val root = (project in file("."))
  .settings(
    fork in run := true
)


lazy val runDebug = inputKey[Unit]("run in debug")

runDebug := {
      javaOptions in run += "-agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=5005" //this doesn't work

      (run in Compile).evaluated 
    },

I cannot make sbt to set javaOptions correctly. How to use Def.settings with inputTask to define another inputTask ?

Tasks cannot modify settings, instead try commands like so

commands += Command.command("runDebug") { state =>
  s"""set javaOptions in run += "-agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=5005""""::
  "run in Compile" :: state
}
