类 'androidx.compose.ui.platform.ComposeView' 由新的 Kotlin 编译器后端编译，旧编译器无法加载

这是我的 onCreate 方法：

override fun onCreateView(
    inflater: LayoutInflater,
    container: ViewGroup?,
    savedInstanceState: Bundle?
): View? {
    return inflater.inflate(R.layout.fragment_delivered, container, false).apply {
        findViewById<ComposeView>(R.id.compose_view).setContent {
            MaterialTheme {
                Surface {
                    Text("Hello")
                }
            }
        }
    }
}

编写版本：

accompanistVersion = "0.1.9"
composeVersion = '0.1.0-dev17'

应用程序.gradle

buildFeatures {
        compose true
        dataBinding true
    }
    composeOptions {
        kotlinCompilerVersion rootProject.kotlinVersion
        kotlinCompilerExtensionVersion rootProject.composeVersion
    }

我正在使用Androidx,android jetpack导航带导航抽屉不显示后退按钮和mobile_navigation.xml中给出的标题,导航我试过用nav_view.setupWithNavController(navController)不能正常工作,工作室显示未解决的符号.我已经为项目添加了必需的依赖项

java.lang.RuntimeException:找不到com.qbitstream.salesmanagementsystem.data.AppDatabase的实现.androidx.room.Room.getGeneratedImplementation(Room.java:94)中不存在AppDatabase_Impl

我在gradle文件中添加了所有内容.我的gradle文件如下所示
