SBT documentation have a perfect manual on how to update logging level for whole project or just for one task.

You need to do something like this:

set logLevel in compile := Level.Error

If you want to set this level in your sbt file, you could do that, by adding this line into your build.sbt file

logLevel := Level.Error

Also if you want to specify logLevel only for compile task it will be a little bit tricky, since you're probably need to set level for dependent tasks as well.

For more information take a look here - http://www.scala-sbt.org/release/docs/Howto-Logging.html
