I am trying to use this tool to port a project to 2.13.11 (with warnings as errors). I have followed the instructions at https://scalacenter.github.io/scala-3-migration-guide/docs/tooling/scala-3-migrate-plugin.html but am running into two errors. If I use jdk18+, I get an error about incompatible class version numbers. If I used jdk 17, I get: Failed to run scalafix with ProcedureSyntax, fix.scala213.ExplicitNullaryEtaExpansion, fix.scala213.ParensAroundLambda, fix.scala213.ExplicitNonNullaryApply, fix.scala213.Any2StringAdd on /home/lakin/work-repos/playstrategy/lila/modules/tv/src/main/TvTrouper.scala because missing symbol: jdk.internal.HotSpotIntrinsicCandidate

Unsure if I'm using the wrong jdk version, or if a dependency is using the wrong jdk version. Note that I have only run the migrate-syntax tv command so far.

Thanks for reporting this issue.

Unfortunately I could not reproduce it. I tried to run migrate-syntax on OpenJDK 18 and it worked fine. I tried on the newer version of the plugin and the older.

Could you maybe try to run the latest version of the plugin, 0.6.1, to see if it fixes the error? Otherwise what is your Java distribution and version?
