问题：

项目接入Hilt后编译时报ClassCastException错误：

Caused by: java.lang.ClassCastException: com.agile.base.DaggerBaseApplication_HiltComponents_SingletonC$ActivityRetainedCImpl$ActivityCImpl cannot be cast to com.example.myapplication.MainActivity_GeneratedInjector
        at com.example.myapplication.Hilt_MainActivity.inject(Hilt_MainActivity.java:67)
        at com.example.myapplication.Hilt_MainActivity$1.onContextAvailable(Hilt_MainActivity.java:38)
        at androidx.activity.contextaware.ContextAwareHelper.dispatchOnContextAvailable(ContextAwareHelper.java:99)
        at androidx.activity.ComponentActivity.onCreate(ComponentActivity.java:322)
        at androidx.fragment.app.FragmentActivity.onCreate(FragmentActivity.java:273)
        at com.example.myapplication.MainActivity.onCreate(MainActivity.kt:22)

原因：

BaseApplication存在另一个模块中

解决办法：

将BaseApplication移到主项目模块中
