java toolchain greater than jvm-8 fails with scala 2.12.17

[tnielens]

scala 2.12.x does not support -target > jvm-1.8. The option is deprecated in scala/scala#10109 for scala 2.12.17.

Expected Behavior

Compilation should succeed.

Current Behavior

Compilation fails.

Context

I can't upgrade a project to latest scala version with a jvm toolchain.

Steps to Reproduce

Compiling some scala code with a toolchain greater than jvm 8 fails with:

> Task :compileScala
'jvm-1.11' is not a valid choice for '-target'
bad option: '-target:jvm-1.11'

with this toolchain configuration:

java {
    toolchain {
        languageVersion = JavaLanguageVersion.of(11)
    }
}

Your Environment

gradle 7.5.1
scala 2.12.17
OpenJDK Runtime Environment Temurin-11.0.15+10 (build 11.0.15+10)
