target/scala-2.13/src_managed/main/scalapb/example/x/X.scala:52:12: under -Xsource:3, inferred Seq[example.x.X] instead of Seq[example.x.X.Recognized] [quickfixable]
[error] Scala 3 migration messages are errors under -Xsource:3. Use -Wconf / @nowarn to filter them or add -Xmigration to demote them to warnings.
[error] Applicable -Wconf / @nowarn filters for this fatal warning: msg=<part of the message>, cat=scala3-migration, site=example.x.X.values
[error]   lazy val values = scala.collection.immutable.Seq(Z, A, B, C)
[error]            ^
[error] one error found
[error] (Compile / compileIncremental) Compilation failed

note

Emit migration warnings under -Xsource:3 as fatal warnings, not errors; -Xmigration disables fatality
