The question is any command for clear screen for sbt interpretive console , like cls in DOS shell or clear in bash
My googling skill did not helped
update : i am using console2 with windows power shell

Answer 1

In bash you should be able to use Ctrl+L, on OSX you can also use Cmd+K.

Answer 2

This specifically helps when you're doing something in continuous mode, ala `compile:
maxErrors := 5
triggeredMessage := Watched.clearWhenTriggered
This works as of 0.13.7. The second line clears the screen before each command runs. The first line limits the number of errors. With this config, you only ever have one screen full of errors to work through. Obviously could adjust maxErrors depending on your sbt window.

Answer 3

Sbt will load ~/.sbt/1.0/build.sbt as global settings.
commands += Command.command("cls") { state =>
print("\033c")
state
}
Then you can run any commands with cls. For example:
~;cls;compile
~;cls;testOnly
