Compilation error during cross builds

[mijicd]

I have the following class hierarchy:

import com.github.plokhotnyuk.jsoniter_scala.macros._
import com.github.plokhotnyuk.jsoniter_scala.core._

final case class Container(a: Option[Int], b: Option[String], src: Source)

object Container {
  implicit val codec: JsonValueCodec[Container] =
    JsonCodecMaker.make(CodecMakerConfig.withDiscriminatorFieldName(None))
}

sealed trait Source

object Source {
  case object A extends Source
  case object B extends Source
  case object C extends Source
}

While it seems to pass tests and work for single scala version, trying to do the cross-version publish (or any other cross-version task) fails with:

Cannot evaluate a parameter of the 'make' macro call for type

I know this is a known type of error, but what would be the recommended way to overcome this issue?

Please find a minimal failing example here. Running a simple +publishLocal should fail with the described error.

As a workaround, please use the JsonCodecMaker.makeWithoutDiscriminator macro call (that is available since v2.6.0) instead of JsonCodecMaker.make(CodecMakerConfig.withDiscriminatorFieldName(None))

@plokhotnyuk makeWithoutDiscriminator worked as a charm! Many thanks for prompt fix! 👏 🎉

[plokhotnyuk]

Reopening because the source of the problem (using of Eval.eval for passing of parameters to the make macro that can be used in the compile-time) is not fixed yet.

The full list of Eval.eval calls used in the jsoniter-scala library are listed here: scalacenter/scala-3-migration-guide#11

Yet another workaround that could help for other configurations of derivation is adding intermediate +compile:

[atais]

just encountered this issue during casual publish without compile step before it, and it seems to be linked.

[error] java.lang.AssertionError: assertion failed: pkgClass = package <root>, sym = package com, existing = package com (depth=0)
[error]   protected implicit val ErrorBodyCodec: JsonValueCodec[ErrorBody] = JsonCodecMaker.make(SearchModelConfig)
[error]                                   

But I am using quite old version 2.4.
At first I thought it's an issue with SBT, but this is actually jsoniters fault?

Thanks

Seeing the same in jsonrpclib with: JsonCodecMaker.make(CodecMakerConfig.withSkipNestedOptionValues(true)), after moving to sbt.

@kubukoz Have you tried any workaround yet?

If nothing works for you then I can add a pre-configured macro call for your case: JsonCodecMaker.makeWithSkipNestedOptionValues.

I tried having an intermediate compile, but it doesn't seem to always work the first time. I even did:

(sbt compile || sbt compile)
sbt ci

and that still failed in https://github.com/neandertech/jsonrpclib/actions/runs/14322194513/job/40154400613?pr=75. We're using projectmatrix, so + should have no effect.

That would be great 😅 but maybe there's an option that doesn't require changes in the lib.

@kubukoz Please peek the latest release and check if it works for you:
https://github.com/plokhotnyuk/jsoniter-scala/releases/tag/v2.34.0

forgot about one problem... we're on SN 0.4, because Cats Effect. I did notice we're on an older jsoniter though, let me try with 2.30.2 (the latest with SN 0.4 support)
