Suppress warning “Access to field exceeds its access rights” in Groovy - groovy

Question

I write a Groovy script and I need to access a field that has a private access modifier. This works fine but generates a warning:
Access to <field_name> exceeds its access rights
I want to supress this warning. What value of #SuppressWarnings annotation do I have to use in order to achieve it?
I've tried #SuppressWarnings("all") and it works fine but I would like to have more granular control over suppressions. I've also tried #SuppressWarnings("AccessingNonPublicFieldOfAnotherObject") but it has no effect.
Below how this warning looks in IntelliJ:
Unfortunately automatic hint doesn't suggest any sensible solution:

Answer 1

If you are talking about IntelliJ warning:
then you can hit Alt+Enter on the offender and choose "Suppress for method" as follows:
after which you will see #SuppressWarnings("GroovyAccessibility") over your test method:

Answer 2

I had this "problem" when I had buildSrc folder in Gradle-project which contained Kotlin code for my Gradle build scripts and it was used in Groovy code.
Seems like it was because I was accessing private variable field and not the getter. Kotlin makes field private by default. I solved this by using #JvmField in Kotlin code which makes the variable field public and does not generate getter for that field.
// groovy in gradle build script
compileOptions {
sourceCompatibility(CompileOptions.javaVersion)
}
// kotlin in buildSrc (this gives the warning)
object CompileOptions {
val javaVersion = JavaVersion.VERSION_11
}
// kotlin in buildSrc (this does not give the warning as field is now public)
object CompileOptions {
#JvmField val javaVersion = JavaVersion.VERSION_11
}
