我的 RCP 应用程序的项目资源管理器视图中有一个树查看器。我的产品完全处理资源（“org.eclipse.emf.ecore.resource.Resource”）中的加载、值检索和更新值。我有一个创建项目菜单项，用于创建新项目。项目创建操作完成后，在项目文件夹中创建了一个新文件。我有一个标准文件，我需要在创建项目本身时加载它。因此，在整个应用程序中，我处理了 2 个文件（标准文件和在项目创建操作期间创建的文件）。当我在 Eclipse 中运行 rcp 产品时，它工作正常，项目创建过程完成后，项目节点出现在树中，当我尝试展开项目节点时，它显示子节点。
我试图将它作为 Eclipse 产品文件中的 rcp 产品导出。当我尝试创建项目时，项目节点显示在树查看器中，但是当我尝试展开项目节点时，它下面什么都没有显示。为什么不显示项目节点的子节点。子节点应取自项目创建过程中创建的文件。该文件在项目文件夹中完美创建。我认为，这是由于与资源相关的一些问题而发生的。在出口产品时，我们应该关心资源吗？
我也遇到过同样的问题，尽管这门课很丑。

这是 ui 资源未设置的问题，您也需要此扩展点“org.eclipse.ui.navigator.viewer”来创建具有项目浏览器视图 ID 的查看器。希望有帮助。
