我的 JavaFX 项目在编辑器中运行良好，但是当我尝试构建到 .jar 时它不会运行。我正在使用 java 17，所以我需要手动导入它，我已经在 settings.json 中正确导入了库，并在 launch.json 中添加了 vmArgs。当我运行java gui.java- （gui.java 是我的类名）时，我收到错误消息，例如：error: package javafx.application does not exist, error: package javafx.geometry does not exist, error: package javafx.scene does not exist. 我知道我应该使用不同版本的 java 或使用其他 vs code 的东西，但我不知道如何将项目转换为 java 的早期版本，我想使用 vs code。有谁知道我如何获得 .jar 或任何为其工作的可执行文件。我什至可以使用手动编译的 bash 脚本之类的东西，我只需要在编辑器之外运行它。这是我的 gui 代码，我知道它的分配很糟糕。
