Я работаю над приложением Maven Spring Boot (без Интернета, только для рабочего стола). В проекте всего 30 классов, но использование зависимостей загрузки Spring создает в конце банку размером 13 МБ. Можно ли использовать Proguard или любой другой плагин для интеграции с Spring Boot, чтобы уменьшить размер JAR? Мой pom-файл проекта:

Я пытаюсь интегрироваться с плагином proguard, но не могу найти способ заставить его работать. Есть идеи для выполнения sh этой задачи?

Примечание: у всех зависимостей есть почти класс, который я использую в своем проекте, я не могу их удалить.
