I expected this to compile and run out of the box. How do I resolve the conflict?

Adding the following two lines to project/plugins.sbt resolves it ref. https://stackoverflow.com/questions/74335368/scala-sbt-version-dependency-binary-compatibility-error-scala-xml:

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

Should the default project template be updated with these two lines?

Thanks,

Should the default project template be updated with these two lines?

No, it should not. Like @ihostage already answered it seems you make use of outdated libraries:

• Regarding

  +- org.jmotor.artifact:artifact-versions_2.12:1.0.3   (depends on 1.1.0)
  

  If you upgrade artifact-versions to 1.0.7 or newer it should work. I can see in the pom file that with version 1.0.7+ scala-xml 2.x is pulled in. Also see Bump scala-xml and some other dependencies aiyanbo/artifact-verions#1
• Regarding

  +- org.scalariform:scalariform_2.12:0.2.6             (depends on 1.0.6)
  

  Just do not use scalariform anymore. It's an outdated, 5 year long unmainainted project. Use sbt-scalafmt instead: https://github.com/scalameta/sbt-scalafmt

[ihostage]

Hi, @kaared!
The root cause is

[error] +- org.scalariform:scalariform_2.12:0.2.6 (depends on 1.0.6)
[error] +- org.jmotor.artifact:artifact-versions_2.12:1.0.3 (depends on 1.1.0)

Are you sure that you don't have a Scalariform and JMotor as global Sbt plugins in $HOME/.sbt/1.0/plugins?

Because Play Java Seed doesn't use it 🤔

Thanks, @ihostage and @mkurz -- outdated global plugin libraries are indeed the root cause here. I've commented out the two libraries for now, but will try to also update them later to see how that goes. The entries weren't documented with which project uses them so tracking that down might require some legwork since it's been several years. :) Anyway, thanks for your help in resolving this -- much appreciated! 👍
