After I filed this, I then filed an issue at scala 3 with more detailed information.

My system is:

java version "11.0.12" 2021-07-20 LTS
Java(TM) SE Runtime Environment 18.9 (build 11.0.12+8-LTS-237)
Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.12+8-LTS-237, mixed mode)

  • Scala code runner version 3.2.0 -- Copyright 2002-2022, LAMP/EPFL

    "org.scalikejdbc" %% "scalikejdbc" % "4.0.0",
    "org.scalikejdbc" %% "scalikejdbc-core" % "4.0.0",
    "org.scalikejdbc" %% "scalikejdbc-interpolation" % "4.0.0",

Doesn't seem to matter, either of these bash SHELL environments show the problem:

  • MINGW64_NT-10.0-19044 d5 3.3.6-341.x86_64 2022-09-20 22:07 UTC x86_64 Msys
  • CYGWIN_NT-10.0-19044 d5 3.3.6-341.x86_64 2022-09-05 11:15 UTC x86_64 Cygwin

The following Minimally Reproducible Example triggers the problem:

  import scalikejdbc._
  implicit val session: AutoSession.type = {
    AutoSession // ad-hoc session provider
  }
  def main(args: Array[String]): Unit = ()
  • Store it to a file named autoSessionBug.sc
  • Place two libraries in your classpath:
    lib/scalikejdbc-core_3-4.0.0.jar
    lib/scalikejdbc-interpolation_3-4.0.0.jar
  • Issue either of thses command lines:

bash shell command line:

/opt/scala3/bin/scala -cp 'lib/scalikejdbc-core_3-4.0.0.jar;lib/scalikejdbc-interpolation_3-4.0.0.jar' autoSessionBug.sc

CMD.EXE session command line:

\opt\scala3\bin\scala.bat -cp "lib/scalikejdbc-core_3-4.0.0.jar;lib/scalikejdbc-interpolation_3-4.0.0.jar" autoSessionBug.sc

Here's what I get:
