The @ClassRule 'resources' must be static Kotlin

Question

I am getting this error:

org.junit.internal.runners.rules.ValidationError: The @ClassRule 'resources' must be static.

When setting up my Dropwizard Kotlin application.

Answer 1

The variable that it is complaining about must be annotated with @JvmField and inside of a companion object. So, for example:

companion object {
    @ClassRule
    @JvmField
    val resources = ...
}
