scala - この例外「dotc: Bad symbolic reference.」の意味

Question

Scala 3で作業し、いくつかの既存のライブラリを使用したいと考えています。この例は Scala 2.13 で動作します。

コンパイルすると、次の例外が発生します。

dotc: Bad symbolic reference. A signature in ../dmn-engine-1.4.0.jar(org/camunda/dmn/parser/ParsedDmn.class)
refers to Serializable/T in package scala which is not available.
It may be completely missing from the current classpath, or the version on
the classpath might be incompatible with the version used when compiling ../dmn-engine-1.4.0.jar(org/camunda/dmn/parser/ParsedDmn.class).

これが私のbuild.sbt

lazy val extension = project
  .in(file("extension"))
  .settings(scalaVersion := dottyVersion,
    libraryDependencies ++= Seq(
      ("org.camunda.bpm.extension.dmn.scala" % "dmn-engine" % "1.4.0").withDottyCompat(scalaVersion.value),
      "com.novocode" % "junit-interface" % "0.11" % "test",
      "org.scalatest" %% "scalatest" % "3.2.2" % Test
    ),

    scalacOptions ++= {
      if (isDotty.value) Seq("-source:3.0-migration") else Nil
    }
  )

更新 OK、2.12で動作し、2.13で次のエラーが発生します。
