java - JDesktop: リソース マップ パスの設定方法

Question

org.jdesktop.application 依存関係を使用しており、いくつかのリソースをロードしたいと考えています。gradle プロジェクトは次のように構成されています。

• main.java.myproject
• main.resources

を使用してリソース マップを読み込みたい場合getResourceMap()。プロパティを読み取らないため、これらのファイルは に保存する必要があると思いますmain.java.myproject.resources。プロジェクト構造を維持するためにリソース マップのパスを設定するにはどうすればよいですか?

コード例:

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