looks like this is no longer needed, after Java 8 deprecation PR is merged

This file is now generated from build.sbt and CI fails if it detects it is not in sync.
When we'll update the branch with changes in main, we'll just need to run sbt githubWorkflowGenerate to have this updated.

What exactly targets.tar will contain?

Is it related to new Magnolia version?

yes, those are required by magnolia with scala 3. Some macros are generating too long inlines.

can you explain what this option means?
There was a problem hiding this comment.
source:3.0-migration instructs the scala 3 compiler to run in migration mode. This is the default from sbt-typlevel when cross-building with scala 2 (the sources are the same).
However, with this option, the compiler fails on the dedicated scala-3 folder because sources are not in the scala 2 style. See discussion scala/scala3#16720

so we still don't want to cross-build with scala3?

is it really needed in scala3? I thought it is only 2.12 .vs 2.13 issue
There was a problem hiding this comment.
scala 2.13 and scala 3 have the same collection IIRC, but we still need the shim layer to get the code cross-build with scala 2.12. I think this can be removed when we stop 2.12 support.
