我在 github上创建了一个小项目，用于探索 ScalaFx 以及我想在更大项目中使用的其他一些东西。目前，它包括一个子项目，这是一个使用 ScalaFX 和 ScalaFXML 编写的简单计算器。
该项目使用 SBT 命令构建并运行良好calculator/run。
我现在正在尝试使用 sbt-native-packager 打包它。我添加了一个名为“exemple-cli”的简单项目（来自 sbt-native-packager 的文档），它可以很好地打包exemple-cli/stage（我在 exemple-cli/target/universal/stage 中得到了预期的结果）。但是，当我运行命令时calculator/stage，出现以下错误：

显然，ScalaFXML 用于为控制器生成代理类的宏存在错误，但这仅在使用 sbt-native-packager 打包时发生，而不是仅在使用 SBT 编译时发生......有谁知道可能导致这种情况的原因?
