我正在尝试使用Eclipse使用Scene Builder打开FXML文件。我右键单击fxml文件，然后单击“使用SceneBuilder打开”按钮。但是，场景创建器无法打开。然后，我尝试创建一个新项目并创建一个新的fxml文档。 scenebuilder打开新的fxml文件。我想文件本身有问题。
这是我的fxml文件。

可能您正在使用11+版本的场景构建器，并且该特定版本不支持真棒字体。
您可以尝试取消安装当前的场景构建器并安装场景构建器8.x
希望此方法可以解决您的问题😊
问题在这里<?import de.jensd.fx.glyphs.fontawesome.FontAwesomeIconView?>。无法识别。也许您可以尝试此How to use font awesome in a fxml project (javafx)
