I tried updating specs2 in my example repo and found that migrating to 4.19.1 did not work automatically.

Project uses specs2 and cats-effect-testing-specs2 (scala 3), link to project https://github.com/amumurst/highgarden

    "org.specs2"                 %% "specs2-core"                % "4.19.0" % Test,
    "org.typelevel"              %% "cats-effect-testing-specs2" % "1.5.0"  % Test

cats-effect-testing-specs2 depends on 4.17.0 (from inspecting evictions in sbt) org.specs2:specs2-core_3:4.17.0 (evicted by 4.19.1)]. So evicting from 4.17.0=>4.19.0 is ok, not to 4.19.1. Pr from steward to update in CE testing (typelevel/cats-effect-testing#413)

Running testOnly no.amumurst.http.CarEndpointsSpec on 4.19.0 completes successfully.

Changing to version 4.19.1 spits out this instead:

Do we have changelog or commits diff between two versions somewhere?

This is weird, the only code change that has gone in is here: https://github.com/etorreborre/specs2/pull/1128/files. It is just adding one object, so I don't think that is a problem.

The other change which could have an impact on compatibility is this one: b60527a.

@amumurst maybe you can try upgrading your scala version here: https://github.com/amumurst/highgarden/blob/master/build.sbt#L28.

@lenguyenthanh on the other hand you don't seem to have the same issue since you are already on Scala 3.2.1: https://github.com/lichess-org/scalachess/blob/master/build.sbt#L35. Is your error coming from a full recompilation?

yes, I got this after full recompilation.

I checked and updating scala version to 3.2.1 does not help my project either. Done full recompilation (even deleting all target folders). Also tried both jdk 8, 13 and 17 just for good measure, no change.

Ok, I think I understand the situation. I got confused with my own set-up for Scala2 / Scala3 and the 4.x / 5.x series. The version 4.19.1 that you got was actually produced from the main branch which is for the 5.x series.

I have now published 4.19.2 which is from the specs2-4.x branch for Scala2 and the specs2-cross branch for Scala3.

@amumurst I tested it on your project and all the tests pass.
