Я использую зависимость org.jdesktop.application и хочу загрузить некоторые ресурсы. Gradle-проект структурирован в:
- main.java.myproject
- main.resources
Когда я хочу загрузить карту ресурсов, используя getResourceMap(). Он не читает никаких свойств, поэтому я думаю, что эти файлы должны храниться в main.java.myproject.resources. Как задать путь к карте ресурсов, чтобы сохранить структуру моего проекта?
Пример кода:
public MyView(SingleFrameApplication app) {
super(app);
initComponents();
ResourceMap resourceMap = getResourceMap();
resourceMap.getInteger("timeout"); // <-- NullPointerException
}
