Плагин Proguard Maven не использует указанную версию proguard, и поэтому я получаю следующую ошибку:
(Can't process class [com/sun/javafx/charts/ChartLayoutAnimator.class] (Unsupported class version number [54.0] (maximum 52.0, Java 1.8)))

Дайте мне знать, если у вас есть какие-либо идеи, как я могу заставить плагин использовать более свежую версию.

Оказывается, вам нужно закрыть элемент выполнения перед открытием конфигурации.
