Thank you for reporting! What happens if you add scalaVersion := "2.12.12"
to your build.sbt file? I am able to reproduce with your build settings but I'm unable to reproduce with that setting added.
I opened #13 to make nativeImage
work with any Scala version, including older versions like 2.12.10. A workaround is to use 2.12.12 in the meantime.
confirmed: works fine with 2.12.2! don't laugh, but that was exciting to see it work!
Describe the bug
An extremely simple example fails to generate a native executable.
To Reproduce Steps to reproduce the behavior:
create the following three files in an empty directory:
% cat build.sbt enablePlugins(NativeImagePlugin) mainClass.in(Compile) := Some("Prog") % cat Prog.scala object Prog { def main(args: Array[String]): Unit = println("hi!") } % cat project/build.properties sbt.version=1.3.13
start sbt and issue the 'nativeCompile' command:

a native image for the trivial program should have been created. or an error message that explains the problem in an understandable way?

Additional context
the same result occurs if JDK 11 is used instead of 14.
