Eclipse 2022-12创建FXML文件报错：WidgetProperties类缺失

在JavaFX项目中尝试创建新FXML文件时弹出错误，使用Eclipse IDE 2022-12版本时出现此问题，但在另一台安装Eclipse IDE 2022-06版本的电脑上可正常执行。请问这是版本更新导致的问题吗？是否有补丁可以解决该问题？

错误日志如下：

这个问题确实是Eclipse版本更新引发的兼容性问题。从错误日志可以看出，org.eclipse.fx.ide.ui_3.8.0.202204150904插件无法找到org.eclipse.jface.databinding.swt.WidgetProperties类，原因是Eclipse 2022-12版本对JFace Databinding组件的包结构或依赖关系做了调整，而当前使用的e(fx)clipse插件版本（3.8.0）没有适配这个变化。

可以通过以下几种方式解决：

• 升级e(fx)clipse插件：打开Eclipse的「帮助」->「Eclipse Marketplace」，搜索e(fx)clipse，安装适配Eclipse 2022-12的最新版本，安装完成后重启Eclipse即可。
• 手动补充缺失依赖：如果找不到适配的插件版本，可通过「帮助」->「安装新软件」，添加对应Eclipse版本的官方更新源，安装「JFace Databinding SWT」组件，确保插件能找到所需的类文件。
• 临时替代方案：若暂时无法升级插件或依赖，可手动创建FXML文件——在项目目标目录右键新建文本文件，命名为xxx.fxml，直接编写FXML内容，跳过向导创建流程。
