Android Studio 3.0 kotlin扩展功能“未解决的参考”

我正在尝试将我的项目更新为使用Android Studio 3.0 Beta 2，并在我的Kotlin扩展功能中出现错误。 我有一个模块sdk ，其中包含一些提供扩展功能的Kotlin文件，例如：

 fun Context.hasPermission(permission: String): Boolean = ContextCompat.checkSelfPermission(this, permission) == PackageManager.PERMISSION_GRANTED 

我在其他两个模块中使用了这个函数，我已经从compile project(':sdk')更改为implementation project(':sdk') 。 当我现在编译我得到的错误：

 Unresolved error: hasPermission 

还有什么我应该做的更新时获得跨模块的这些扩展功能？

UPDATE

我改变了函数签名不再是一个扩展函数，而是看起来像：

 fun hasPermission(context: Context, permission: String): Boolean ContextCompat.checkSelftPermission(context, permission) == PackageManager.PERMISSION_GRANTED 

我仍然得到相同的错误，如果我把它包装在一个类或它的工作对象。

 object ContextUtils { fun hasPermission(context: Context, permission: String): Boolean ContextCompat.checkSelftPermission(context, permission) == PackageManager.PERMISSION_GRANTED } 

UPDATE

我用--info --stacktrace标志运行了这个构建，这里是输出（还有很多，但是这似乎是相关的部分）：

UPDATE

删除testCoverageEnabled = true解决了缺少全局函数的问题。 现在我只剩下了我认为属于另一个问题的亚马逊S3的错误。

Answer 1

正如在注释中提到的testCoverageEnabled ，使用testCoverageEnabled导致此问题有一个错误，从而解决了缺少的功能问题。
