java - sbt:对象应用程序不是包的成员

Question

我从 sbt android plugin 成功构建了仅限 Scala 的项目模板.接下来，我尝试将一些 Java 源代码添加到我的项目中，但在 TR.scala 中出现以下错误。 TR.scala 是从 Java 源代码生成的文件。

感谢 Yifan Yu 的 response在 Google 网上论坛中，它似乎是 sbt Android plugin 中的错误.感谢 Jan Berkel，修复了 this release 中的错误.

You have a package path named com.mydomain.myproject.android, so it's confusing the compiler when it tries to compile TR.scala in 'com.mydomain.myproject', because it thinks of 'android.whatever' as a relative path. The plugin tries to prepend _root_. to the Activity source it generates, but it forgets to do so for TR.scala.
