This isn't reverse binary compatible, so we need to relax the version policy setting.

[error] (xml / versionPolicyReportDependencyIssues) Dependencies of module scala-xml:2.0.1+35-9a8b0ef2-SNAPSHOT break the intended compatibility guarantees 'Compatibility.BinaryCompatible' (see messages above). You have to relax your compatibility intention by changing the value of versionPolicyIntention.

[ashawley]

Actually, we are doing that:

versionPolicyIntention := Compatibility.BinaryCompatible,

Oh, it's because of upstream Scala?

[error] Incompatibilities with dependencies of scala-xml:2.0.1
[error]   org.scala-lang:scala3-library_3: incompatible version change from 3.0.1 to 3.1.0 (compatibility: package versioning policy)

[ashawley]

I've added 3.1.0 to the build but disabled the publish step to avoid the versionPolicy error, but also because that is what is intended.

    publish / skip := (CrossVersion.partialVersion(scalaVersion.value) match {
      case Some((3, x)) if x > 0 => true
      case _                     => false
    }),
