Question

我创建了a small project on github来探索ScalaFx和其他一些我想在更大的项目中使用的东西。目前，它包含一个子项目，这是一个使用ScalaFX和ScalaFXML编写的简单计算器。

使用SBT命令calculator/run构建并运行该项目。

我现在正尝试使用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），它与exemple-cli/stage打包得很好（我在exemple-cli / target / universal / stage中得到了预期的结果）。但是，当我运行命令calculator/stage时，我收到以下错误：

显然，ScalaFXML用来为控制器生成代理类的宏有一个错误，但这只发生在使用sbt-native-packager进行打包时，而不是仅仅在使用SBT进行编译时...有没有人知道是什么可能导致这个？

看起来像SI-8771，这是从2.11.1到2.11.2的回归。解决方法是降级到2.11.2或根据注释中提供的详细信息更改宏代码https://issues.scala-lang.org/browse/SI-8771。

使用sbt-native-packager和ScalaFXML进行宏扩展时出现异常
