我无法编译我的Android Kotlin项目.

我不知道这是什么……

Gradle日志：

错误：无法解析以下类的超类型.请确保您在类路径中具有所需的依赖项：
class android.support.v7.app.AppCompatActivity,未解析的超类型：SupportParentable

解决方法:

在我的例子中,我有一个库模块,其中包含一个实现Dagger的HasActivityInjector的抽象应用程序类,以及一个依赖于库的应用程序模块以及扩展基本app类的自己的(非抽象)应用程序类.

我的Gradle依赖项是实现,因此应用程序模块的应用程序类无法访问(即使没有导入,否则问题会立即明显,因为您会收到’无法解决’错误.修复程序是替换dagger实现与api的依赖关系,这使得它们也可用于依赖模块.
