Я пытаюсь работать с JavaFX на Fedora 30, у меня есть java-1.8.0-openjdk, java-1.8.0-openjdk-devel, java-1.8.0-openjdk-headless, java-1.8. Загружены пакеты 0-openjdk-openjfx, java-1.8.0-openjdk-openjfx-devel, работающие над eclipse. Когда я компилирую проект (sorce from https://www.geeksforgeeks.org/javafx-building-a-media-player/), это то, что происходит.
