In IntelliJ (version: 2016.3.1, Scala Plugin version: 2016.3.5), I have a Scala 2.12 (which implies Java 1.8 being required) project where I am selecting "Build/Rebuild Project". I am receiving the following output in the "Messages" windows:
Warning:scalac: there were four deprecation warnings (since 2.12.0); re-run with -deprecation for details
What steps must I take to configure my project such that I can actually see the content of the 4 warnings?
I found another question for IntelliJ 14 which showed how to turn on deprecation warnings, but didn't indicate how to surface the actual content of the deprecation warnings themselves. Any guidance on this would be greatly appreciated.

To install Scala plugin, press Ctrl+Alt+S , open the Plugins page, browse repositories to locate the Scala plugin, click Install and restart IntelliJ IDEA.
In most cases your project JDK is not compatible with Scala or sbt version, try to change the Scala Compile Server SDK. Press Ctrl+Alt+S to open Settings/Preferences dialog. From the options on the left, select Build, Execution, Deployment | Compiler | Scala | Scala Compiler Server.
The Scala plugin extends IntelliJ IDEA's toolset with support for Scala, SBT, Scala. js, Hocon, and Play Framework. Support for Scala, SBT and Hocon is available for free in IntelliJ IDEA Community Edition, while support for Play Framework and Scala. js is available only in IntelliJ IDEA Ultimate.
As of the latest Intellij version at this time, you can also open Settings -> Build, Execution, Deployment -> Compiler -> Scala Compiler, and in Additional compiler options:, append -deprecation.
