使用sbt-native-packager和ScalaFXML進行宏擴展時出現異常

Question

我創建了a small project on github來探索ScalaFx和其他一些我想用於更大項目的東西。目前，它包含一個單獨的子項目，這是一個使用ScalaFX和ScalaFXML編寫的簡單計算器。

該項目使用SBT命令calculator/run建立和運行良好。

我正在嘗試使用sbt-native-packager進行打包。我添加了一個名爲「exemple-cli」（來自sbt-native-packager的文檔）的簡單項目，該項目與exemple-cli/stage（我在exemple-cli/target/universal/stage中獲得預期結果）進行了很好的封裝。然而，當我運行命令calculator/stage，我得到以下錯誤：

顯然，存在與使用ScalaFXML來生成控制器代理類的宏出現錯誤，但是這隻能sbt-包裝時，會發生native-packager，而不是隻編譯SBT時...沒有人有任何想法可能會導致這種情況嗎？

看起來像SI-8771，它是從2.11.1到2.11.2的迴歸。解決方法是降級到2.11.2或根據註釋中提供的詳細信息將宏的代碼更改爲https://issues.scala-lang.org/browse/SI-8771。
