У меня не было успеха, пытаясь преобразовать это в Kotlin и использовать его.
Он работает как Java, но не с моим Kotlin (который я преобразовал с помощью IntelliJ Kotlin Plugin)
проблема заключается в этой части
@PluginFactory
public static AnsiConsoleAppender createAppender(
Я пытался добавить @JvmStatic и получаю эту ошибку:
Невозможно вызвать фабричный метод в классе AnsiConsoleAppender для элемента AnsiConsoleAppender: java.lang.IllegalArgumentException: параметр, указанный как ненулевое, имеет значение null: метод AnsiConsoleAppender $ Companion.AnsiConsoleAppender, фильтр параметров java.lang.reflect.InvocationTargetException
