使用IntelliJ Idea ClassNotFoundException的Android上的Scala(Scala on Android with IntelliJ Idea ClassNotFoundException)

 我尝试使用sbt和maven for android-scala，我非常喜欢maven做整个发布的事情（ProGuard-ing scala standar lib等）。 但是我希望在IDE中开发轻量级重编译循环 - IntelliJ IDEA。 
 
 问题是scala文件无法编译。 我像这样配置了我的项目： 
 
 
 
 创建了android项目 
 
 
 添加scala facet 
 
 
 将scala编译器设置为全局 
 
 
 添加了对scala库（全局）的依赖并将其设置为“提供” 
 
 
 我添加了一个scala对象并从java Activity中引用它。 ClassNotFoundException并强制关闭。 它编译得很干净（而且相当狡猾）。 
 
 我以相同的方式创建了一个普通的旧java项目并使用相同的全局库并且它起作用。 对apk的检查显示它包含scala源（！）文件。 所以显然没有事件尝试编译。 
 
 哦，我的手机已经预装了来自Play商店的scala安装程序。 
 
 我使用IntelliJ IDEA 11社区。 几个月前我第一次尝试这个并且它有效。 
 
 更新它可以在不同的机器上运行。 

I tried using sbt and maven for android-scala and I quite like maven for doing the whole release thing(ProGuard-ing the scala standar lib etc). But I want lightweight recompile cycle for development inside my IDE - IntelliJ IDEA.
 
The problem is scala files wont't compile. I configured my project like this:
 
 
 
created android project
 
 
added scala facet
 
 
set scala compiler to global
 
 
added dependency on scala library(global) and set it to "provided"
 
 
I added a scala object and referenced it from java Activity. ClassNotFoundException and force close. It compiles cleanly(and quite quckly).
 
I created a plain old java project the same way and using same global libraries and it worked. An inspection of the apk revealed it contained scala source(!) file. So apparently it didn't event try to compile. 
 
Oh, and my phone has scala preinstalled with scala installer from play store.
 
I use IntelliJ IDEA 11 community. I first tried this a few months ago and it worked.
 
update it works on a different machine.
