This is related to "How to suppress info and success messages in sbt?", but that was for a previous version.
Back in sbt 0.13.x, and currently on the sbt 1.x website, it says that using "-- before the logging level" can "set the logging level before any commands are executed on startup". Meanwhile, the referenced SO post points to a change that says "it is strongly encouraged to migrate to the single hyphen options: -error, -warn, -info, and -debug".
Neither syntax --error nor -error seem to quiet sbt. Following the website documentation syntax:
mkdir project
echo 'sbt.version=1.0.4' > project/build.properties
sbt sbtVersion --error
This produced a bunch of messages, culminating with:
[info] 1.0.4
[warn] The `-` command is deprecated in favor of `onFailure` and will be removed in 0.14.0
Switching to sbt sbtVersion -error with a single dash removed the warning, but still had the other [info] lines.
FYI switching the version to 0.13.16 doesn't output anything, as I would expect.
Is there a new way in sbt 1.x to suppress messages? I'm guessing this is a bug but asking here just in case following the contribution guidelines.
Edit: Issue #3849 mentioning 1.1.0-RC4 was opened earlier today, and I'm assuming it's the same for the 1.0.x series.
