Question

我正在使用org.jdesktop.application依赖项，并希望加载一些资源。 gradle项目的结构如下：

main.java.myproject
main.resources

当我想使用getResourceMap()加载资源映射时。它不读取任何属性，因此我认为这些文件必须存储在main.java.myproject.resources中。如何设置资源映射的路径以保持我的项目结构？

代码示例：

public MyView(SingleFrameApplication app) {
    super(app);
    initComponents();
    ResourceMap resourceMap = getResourceMap();
    resourceMap.getInteger("timeout"); // <-- NullPointerException
}

Stacktrace：
