我正在尝试将我的项目更新为使用Android Studio 3.0 Beta 2，而且我的Kotlin扩展功能出现错误。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2个模块中使用此功能，我已将其从compile project(':sdk')更改为implementation project(':sdk')。当我现在编译时，我得到错误：
Unresolved error: hasPermission
在更新以跨模块获取这些扩展功能时，我还应该做些什么吗？
更新
我将函数签名更改为不再是扩展函数，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运行的对象中。
object ContextUtils {
fun hasPermission(context: Context, permission: String): Boolean
ContextCompat.checkSelftPermission(context, permission) == PackageManager.PERMISSION_GRANTED
}
更新
我使用--info --stacktrace标记运行构建，这里有输出（还有更多，但这似乎是相关部分）：

更新
删除testCoverageEnabled = true修复了缺少的全局函数的问题。现在我刚刚离开亚马逊S3的错误，我认为这个错误属于另一个问题。
答案 0 :(得分：0)
正如@hotkey在评论中提到的那样，使用testCoverageEnabled导致此问题存在一个错误，将其关闭修复了丢失的函数问题。
