I got a "deprecation warnings; re-run with -deprecation for details" message from SBT when trying to compile or run my project code. How do I add -deprecation to see the deprecation warnings?
Add this entry to your SBT build.sbt file:
scalacOptions += "-deprecation"
For example, a complete build.sbt file might look like this:
name := "Test 1" version := "1.0" scalaVersion := "2.9.1" resolvers += "Typesafe Repository" at "http://repo.typesafe.com/typesafe/releases/" libraryDependencies += "com.typesafe.akka" % "akka-actor" % "2.0.2" scalacOptions += "-deprecation"
