Scala 3.2.0-RC2 Open Community Build regressions tracker

Each table contains a list of projects that failed to compile with Scala 3.2.0-RC2, but was successfully built with the given previous version. A summary is based only on final and released candidate versions of Scala 3. Information about the last Scala version used for the last successful build might not always be correct, due to lack of data (lack of build for that project with given Scala version)

• Version - version of project being built, single version if both current and last successful build version of project are equal, otherwise ‘LastSuccessfullProjectVersion -> CurrentProjectVersion>’
• Build URL - link to the Open Community Build, containing logs and details of the failed project
• Reproducer issue - link to the reproducer issue to be filled in

Open community build might have applied -source:X-migration flag if it is detected it could possibly fix the build. Summary only contains projects that failed when compiling source or test files of at least 1 sub-project.

All tested projects: 818 Open Community build run: Build #17 - 3.2.0-RC2-all-projects

Notes for issue reproducers: To reproduce builds locally you can use:

scala-cli run https://raw.githubusercontent.com/VirtusLab/community-build3/master/cli/scb-cli.scala -- reproduce --locally BUILD_ID

BUILD ID can be found in the BUILD_URL columns (eg. Open CB #BUILD_ID) Helpful options for reproducer scripts:

• --scalaVersion VERSION run build with the selected version of Scala (to check if the problem existed in given release)
• --withUpstream - build also all upstream dependencies of failing project
• --locally - checkout and build the project locally, without this flag it would try to start a minikube cluster to make the reproduction environment exactly the same as in the Open Community Build run (eg. to compile with the same version of the JDK)

@armanbilge technically, that is called a weird regression.

[WojciechMazur]

@armanbilge I can confirm that the issue with your project is only happening in our testing environment due to a more strict resource policy (limited memory inside the container) though due to reduced -Xss leading to StackOverflowError. It can re reproduced when using the scala-cli script listed at the begging of the issue (without --locally flag). It can be ignored
