How to "re-run with -deprecation for details" in sbt?
sbt shell
While in sbt shell (if you don't want to change your build.sbt
):
$ sbt
> set ThisBuild/scalacOptions ++= Seq("-unchecked", "-deprecation")
> compile
> exit
Due to in ThisBuild
, set
applies the settings to all sub-projects, as well.
Command Line
You could also run the above as a single command on command line.
sbt '; set ThisBuild/scalacOptions ++= Seq("-unchecked", "-deprecation") ; compile'
The trick is to use ;
(semicolons) to separate commands and '
(ticks) to include all ;
-separated commands as a single argument to sbt.
sbt < 1.x
Instead of ThisBuild/scalacOptions
use scalacOptions in ThisBuild
scalacOptions := Seq("-unchecked", "-deprecation")
Add this setting to your build.sbt, and, if you have a multi-module project, add it to every project's settings.
