Reproduction steps
Scala version: 2.13.13
Tested with Scala 3 versions for cross compiled project: 3.3.1 and 3.3.2
reproduction-sbt.zip
run with sbt "base/publishLocal; projectC/publishLocal"
- Define ADT in Scala 3, create a jar out of it
package testlib
enum ADT:
case SingletonCase
case ClassCase(x: String)- Define Scala 2 project that uses Scala 3 JAR
package app
object Main {
def main(args: Array[String]): Unit = {
println(testlib.ADT.SingletonCase)
println(testlib.ADT.ClassCase("foo"))
}
}- Try to create documentation for Scala 2 project, (
sbt Compile/doc)
Problem
Compilation fails with
error] stack trace is suppressed; run last projectC / Compile / doc for the full output
