title: Can the incremental compiler in sbt be turned off for CI builds?
body: <p>While looking for a way to improve compile times on our build server, I came across this issue about <a href="https://github.com/sbt/sbt/issues/1078" rel="nofollow">overhead added by the incremental compiler</a>.  Since our build server checks out a fresh copy of the source and builds from scratch each time, it would be nice to be able to disable the incremental compiler completely and not have to pay for something that will not be used.  Is this possible?</p>
