Use Scala Native test-interface-sbt-defs instead of test-interface

[zainab-ali]

See scala-native/scala-native#4844

Testing libraries and frameworks should depend on Scala Native's test-interface-sbt-defs, not test-interface.

• test-interface-sbt-defs defines a common interface for unit tests. It follows early-semver versioning.
• test-interface is a server implementation that must match the version of the Scala Native plugin. It follows strict versioning.

This was picked up by SBT 1.12.10, which added eviction checks for test dependencies.

How to reproduce

Create an SBT project with the following:

// project/build.properties
sbt.version = 1.12.11

// project/plugins.sbt
addSbtPlugin("org.scala-native" % "sbt-scala-native" % "0.5.11")

// build.sbt
scalaVersion := "3.3.7"
enablePlugins(ScalaNativePlugin)

ThisBuild / evictionWarningOptions := (ThisBuild / evictionWarningOptions).value
  .withConfigurations(List(Compile, Test))

libraryDependencies += "org.scalatest" %%% "scalatest" % "3.2.20" % Test

The sbt update command gives:

[error] (update) found version conflict(s) in library dependencies; some are suspected to be binary incompatible:
[error]
[error] 	* org.scala-native:test-interface_native0.5_3:0.5.11 (strict) is selected over 0.5.10 for test

@zainab-ali I tried to reproduce the problem in branch #2428 by upgrading the sbt version to 1.12.12, but unable to reproduce the mentioned error, I wonder if I should include the following in your example into the build to reproduce:

ThisBuild / evictionWarningOptions := (ThisBuild / evictionWarningOptions).value
  .withConfigurations(List(Compile, Test))

I am not sure what it is doing, mind to help explaining?

Thanks.

Thanks for looking into this! To reproduce you'll need to set the following options:

ThisBuild / evictionWarningOptions := (ThisBuild / evictionWarningOptions).value
  .withConfigurations(List(Compile, Test))

Note that these are a default in SBT 2.0.

This applies the SBT eviction check to both Compile and Test configurations. In SBT 1.12.10 and below, the eviction check only applied to Compile dependencies. This meant that binary incompatibilities in test dependencies would manifest as runtime errors.

SBT 1.12.11 attempted to roll out the eviction check to test dependencies by making the setting above a default. However, this caused almost all Scala Native builds to fail due to testing libraries depending on test-interface instead of test-interface-sbt-defs. To work around this, the evictionWarningOptions default configurations were reverted back to Compile in SBT 1.12.12.
