Even after adding the freeCompilerArgs for inline classes, I still get IDE warnings inside a Gradle plugin test. Do I need to change the following recommended Gradle code at all for build.gradle.kts in a Gradle Plugin module?
https://kotlinlang.org/docs/reference/inline-classes.html#enabling-inline-classes-in-gradle
tasks.withType<KotlinCompile>().configureEach {
kotlinOptions.freeCompilerArgs += "-XXLanguage:+InlineClasses"
// OR "-Xinline-classes"... neither seems to work
}
