Awesome work from @lolgab . Would be nice to have it integrated to scala-xml @ashawley ❤️

wow, the chain of dependencies is quite long 😄 I got there by following the links in softwaremill/sttp#1243

I see code that prevents attempting to build or publish for Scala 3.0 for Scala Native.

I don't see code that prevents non-Native platforms from double-publishing (on both 3.0 and 3.1). Am I missing something or am I wrong to expect that?

I think only for Scala 3.0.x not 3.1.x and higher - It has to do with de-reference syntax !ptr = value https://scala-native.readthedocs.io/en/latest/user/interop.html but I couldn't find the Dotty issue. Ok found it - it was a blocker in 3.0 that worked in Scala 2 - scala/scala3#13282

[SethTisue]

@ekrich I understand that Scala Native doesn't work on 3.0, only 3.1.

my question is about having both 3.0 and 3.1 in crossScalaVersions

to make this more concrete, basically my questions is, shouldn't the build do (pseudocode):

publish / skip := scalaVersion.value.startsWith("3.1") && platform != Native

because on JVM and JS, it doesn't make sense to publish on both 3.0 and 3.1; the artifacts are _3 either way

[SethTisue]

ohhhhh, that already is in build.sbt:

    // Don't publish for Scala 3.1 or later, only from 3.0
    publish / skip := (CrossVersion.partialVersion(scalaVersion.value) match {
      case Some((3, x)) if x > 0 => true
      case _                     => false
    }),

it just isn't in the diffs for this PR — it was already there!

okay, that answers my question, sorry for the noise
