Classloader constraint violation

hi - promising project, would love to use Jib with Mill, I gave it a try in an existing multi module project and encountering the following error:

xxx.docker.buildDocker java.lang.LinkageError: loader constraint violation: loader io.github.atty303.mill.jib.JibClassLoader @69f19c17 wants to load abstract class scala.Option. A different abstract class with the same name was previously loaded by 'app'. (scala.Option is in unnamed module of loader 'app')

    scala.runtime.java8.JFunction0$mcV$sp.apply(JFunction0$mcV$sp.scala:18)

Using it like this:

trait CapacityDockerJibServiceModule extends ScalaModule with JibModule with BuildInfo {
  override def buildInfoMembers: T[Map[String, String]] = T {
    val now = java.time.Instant.now()
    Map(
      "name" -> artifactName(),
      "version" -> GitVersionModule.version(withSnapshotSuffix = true)(),
      "scalaVersion" -> scalaVersion(),
      "millVersion" -> BuildInfo.millVersion,
      "builtAtMillis" -> String.valueOf(now.toEpochMilli),
      "builtAtString" -> now.toString,
      "gitSha" -> gitSha()
    )
  }

  trait CapacityDockerConfig extends DockerConfig {
    override def image = T { "yyy/xxx:latest" }
  }
}
