This doesn't compile:

The correct way to set jvm-target in CLI is without the =. So, your annotation should look like

@file:CompilerOptions("-Xopt-in=kotlin.time.ExperimentalTime","-jvm-target", "1.8")

it works for me after this change.
Proper diagnostic is definitely missing here. I'd appreciate very much if you'll file an issue in YouTrack about it.
