Scala SBT Version Dependency Binary Compatibility Error scala-xml

I have a project that I host on GitHub and I use scala-steward to keep my plugins and dependencies up to date. This worked for a while and now it is turning out to be a nightmare to use such auto updates. Here is the thing. In my plugins.sbt, I have a dependency to scoverage which was updated by scala-steward to version 2.0.6. But the pull request failed to pass through the compile stage and I see the following error:

[error] (update) found version conflict(s) in library dependencies; some are suspected to be binary incompatible:
[error]     * org.scala-lang.modules:scala-xml_2.12:2.1.0 (early-semver) is selected over {1.3.0, 1.2.0, 1.1.1, 1.0.6}
[error]         +- org.scoverage:scalac-scoverage-reporter_2.12:2.0.7 (depends on 2.1.0)
[error]         +- org.scalariform:scalariform_2.12:0.2.0             (depends on 1.0.6)
[error]         +- org.scala-lang:scala-compiler:2.12.16              (depends on 1.0.6)
[error]         +- com.typesafe.sbt:sbt-native-packager:1.5.2 (scalaVersion=2.12, sbtVersion=1.0) (depends on 1.1.1)
[error]         +-             (depends on 1.2.0)
[error]         +- com.github.sbt:sbt-native-packager:1.9.9 (sbtVersion=1.0, scalaVersion=2.12) (depends on 1.3.0)

First of all, it is good that such incompatibilities are reported during compile time to avoid any runtime surprises. But, I'm not sure how to get this fixed. Feels like I have hit a roadblock.

EDIT: Here is my actual project:


  • I had to do the following in my project/plugins.sbt file to get this error fixed:

    ThisBuild / libraryDependencySchemes += "org.scala-lang.modules" %% "scala-xml" % VersionScheme.Always

    I also added the following to my build.sbt:

    ThisBuild / evictionErrorLevel := Level.Info

    But I guess I do not need that in my build.sbt. Hope this helps someone! The Scala community at discord helped me to get this fixed. Thanks to them!
