Я пытаюсь скомпилировать очень простой плагин maven, который по сути копирует содержимое из одной папки в другую, но ArrayOutOfBoundsException продолжает генерироваться во время компиляции некоторым классом, который (я полагаю) обрабатывает аннотации.Я вставлю ниже журналы от компилятора, класса плагина и POM.
Как вы думаете, это может быть ошибкой в инструменте?
Как я могу решить эту проблему?

на случай, если вам интересно, почему яделали эти глупые методы внизу, потому что кое-как они избегали этой ошибки (использование прямой конкатенации строк было одной из причин, по которой я искал)
