Cannot resolve correct version when not using scala 2.12

[rbscgh]

This might be more a sbt issue than this plugin but when i explicitly set

addSbtPlugin("com.thesamet" % "sbt-protoc_2.12_1.0" % "1.0.7")

the resulting download is trying to look for
https://repo1.maven.org/maven2/com/thesamet/sbt-protoc_2.12_1.0_2.12_1.0/1.0.7/sbt-protoc_2.12_1.0-1.0.7.pom

im wanting to cross build my project with

lazy val scala212 = "2.12.18"
lazy val scala213 = "2.13.14"
lazy val scala3 = "3.3.4"

...
crossScalaVersions := Seq(scala212, scala213, scala3)

and changing versions with ++VERSION in sbt doesnt let me proceed with non 2.12 versions due to this issue.

Any idea ? or has anyone run into this as well ?

ive additionally tried

addSbtPlugin("com.thesamet" %% "sbt-protoc_2.12_1.0" % "1.0.7")
dependencyOverrides += {
  val sbtV = (pluginCrossBuild / sbtBinaryVersion).value
  val scalaV = "2.12"
  sbt.Defaults.sbtPluginExtra("com.thesamet" % "sbt-protoc" % "1.0.7", sbtV, scalaV)
}

but also no luck

SBT plugins are always on Scala 2.12. This doesn't limit you from cross-compiling the generated code for any Scala versions. There should be no need to change the scala version of the plugin explicity.
