SBT task to download / fetch a file from a URL

Question

What is a recommended way to write an SBT task that downloads a file from a known URL into a local file?

Older versions of SBT provided IO.download which could be used to download a URL into a local file, but in recent versions (1.2.8) this method is not available and seem to be commented out in the code.

Answer 1

As documented here:

import scala.sys.process._

url("http://...") #> file("somefile") !
