Scala 2.12.4 support

See original GitHub issue

When I try to compile a project with scala 2.12.4 and Java 8:

[ERROR] Failed to execute goal net.alchim31.maven:scala-maven-plugin:3.3.1:compile (default) on project black-marlin-processors-core: wrap: java.lang.reflect.InvocationTargetException: ExceptionInInitializerError: Not a version: 9 -> [Help 1]

And when I run the scala-maven-plugin integ-test build locally with the scala version set to 2.12.4 I see the following:

funny enough, it does compiles with scala 2.12.4 and 2.12.5, only 2.12.6 causes this error for me

could you please share your scala-maven-plugin configuration? I’ve tried 2.12.6 and got aforementioned java.lang.NumberFormatException: Not a version: 9

here’s my config (well, part which is relevant I believe)

    <properties>
        <java.version>1.8</java.version>
        <scala.version>2.12.6</scala.version>

it works fine with 2.12.3

I appreciate your time, thanks!
