CopyOptions

sbt IO 1.0 adds variants of IO.copyFile and IO.copyDirectory that accept sbt.io.CopyOptions().
CopyOptions() is an example of pseudo case class similar to the builder pattern.

import sbt.io.{ IO, CopyOptions }

IO.copyDirectory(source, target)

// The above is same as the following
IO.copyDirectory(source, target, CopyOptions()
  .withOverwrite(false)
  .withPreserveLastModified(true)
  .withPreserveExecutable(true))
