sbt 1.4.3, Linux. Process just hangs on forever, never pressing "any" key, nor ctrl-C, ctrl-D help. Only kill.

[info] Main Scala API documentation successful.
Embedded server listening at
  http://127.0.0.1:4000
Press any key to stop.

Does this still happen with sbt-site 1.4.1? See https://github.com/sbt/sbt-site/pull/163

The issue is that unfiltered.util.RunnableServer does:

        println("Press any key to stop.")
        def doWait(): Unit = {
          try { Thread.sleep(1000) } catch { case _: InterruptedException => () }
          if(System.in.available() <= 0)
            doWait()
        }
        doWait()

But input from sbt doesn't go on standard input.

~But input from sbt doesn't go on standard input.~

Actually it is that System.in.available always returns 0.

Fixed in sbt 1.7 (yet to be released) https://github.com/sbt/sbt/issues/6964
