New warnings under 3.3.7

Question
1

After upgrading my actor library leucine to the latest Scala LTS version 3.3.7 i get these warnings:

[info] compiling 71 Scala sources to leucine/jvm/target/scala-3.3.7/classes ...
[warn] bad option '-Ypickle-java' was ignored
[warn] bad option '-Ypickle-write' was ignored

In the build.sbt file i have:

scalacOptions ++= Seq("-feature","-deprecation","-unchecked","-explain","-Wunused:all","-Wnonunit-statement","-Wvalue-discard")

Searching for these options did not reveal any useful information (in fact, it did not reveal much at all, in the context of Scala).

Edit: In the meantime i found out that the warnings are caused by the line

ThisBuild / usePipelining := true

in the build file. Setting it to false makes them disappear. So obviously, this setting activates both “bad options”.

Can anyone shed some (more) light on this?

I’d suggest opening a ticket at GitHub · Where software is built
