In bash you should be able to use Ctrl+L, on OSX you can also use Cmd+K.
在 bash 中你应该可以使用 Ctrl+L，在 OSX 中你也可以使用 Cmd+K。

This specifically helps when you're doing something in continuous mode, ala `compile:
当你在连续模式下做某事时，这特别有帮助，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.
这适用于 0.13.7。第二行在每个命令运行之前清除屏幕。第一行限制了错误的数量。使用此配置，您只有一个充满错误的屏幕需要处理。显然可以根据您的 sbt 窗口调整 maxErrors。

Sbt will load ~/.sbt/1.0/build.sbtas global settings.
Sbt 将~/.sbt/1.0/build.sbt作为全局设置加载。
commands += Command.command("cls") { state =>
print("3c")
state
}
Then you can run any commands with cls. For example:
然后你可以使用 cls 运行任何命令。例如：
~;cls;compile~;cls;testOnly
~;cls;compile~;cls;testOnly
