Previously, the `nativeImage` task failed with the follow error when using Scala 2.12.10 ``` [error] Error: substitution target for scala.meta.internal.svm_subs.Target_scala_runtime_Statics is not loaded. Use field `onlyWith` in the `TargetClass` annotation to make substitution only active when needed. ``` Now, the error message is ``` outdated Scala version. To fix this problem, add `scalaVersion := "2.12.12"` (or any version newer than 2.12.12) to build.sbt ``` A better fix would be to use the `onlyWith` field as recommended in the native-image error message. However, I failed to get this working.
Fixes scalameta#12. Previously, native-image generation failed if the user had an older version of Scala like 2.12.10. Now, native-image generation works with any Scala version thanks to improvements in the upstream native-image substitutions. The substitutions are now conditionally enabled based on the presence of `releaseFence()` methods. The substitions now have no effect if they are not needed.
