How do I get IntelliJ to display the Scala compilation deprecation warnings
<p>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:</p>

<p><code>Warning:scalac: there were four deprecation warnings (since 2.12.0); re-run with -deprecation for details</code></p>

<p>What steps must I take to configure my project such that I can actually see the content of the 4 warnings?</p>

<p>I found <a href="https://stackoverflow.com/questions/19585575/scala-warnings-intellij-and-compiler-flags">another question for IntelliJ 14</a> 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.</p>
