Sometimes a user may want to rerun their task even if the source files haven't changed. Presently this is a little annoying because you have to hit enter to stop the build and then up arrow or <ctrl+r> plus enter to rebuild. It's more convenient to just be able to press the 'r' key to re-run the task. To implement this, I had to make the watch task set up a jline terminal so that System.in would be character buffered instead of line buffered. Furthermore, I took advantage of the NonBlockingInputStream implementation provided by jline to wrap System.in. This was necessary because even with the jline terminal, System.in.available doesn't return > 0 until a newline character is entered. Instead, the NonBlockingInputStream does provide a peek api with a timeout that will return the next unread key off of System.in if there is one available. This can be use to proxy available in the WrappedNonBlockingInputStream. To ensure maximum user flexibility, I also update the watchHandleInput Key to take an InputStream and return an Action. This setting will now receive the wrapped System.in, which will allow the user to create their own keybindings for watch actions without needing to use jline themselves. Future work might make it more straightforward to go back to a line buffered input if that is what the user desires.
