Android app crashing when implementing a HiltViewModel

Question

My HiltViewModel with a database:

@Module
@InstallIn(SingletonComponent::class)
object AppDatabaseModule {
    @Provides
    @Singleton
    fun providesAppDatabase(
        @ApplicationContext applicationContext: Context,
    ): AppDatabase = Room.databaseBuilder(
        context = applicationContext,
        klass = AppDatabase::class.java,
        name = "database",
    ).build()

    @Provides
    fun providesDataDao(db: AppDatabase): DataDao = db.dataDao()
}


@HiltViewModel
class DataModel @Inject constructor (
    dataDao: DataDao,
) : ViewModel() {
    val data: StateFlow<List<Data>> = dataDao.getAll()
        .stateIn(
            scope = viewModelScope,
            started = SharingStarted.WhileSubscribed(5),
            initialValue = emptyList(),
        )
}

@Database(entities = [Data::class], version = 1)
abstract class AppDatabase: RoomDatabase() {
    abstract fun dataDao(): DataDao
}


@Entity (tableName = "data")
data class Data(
    @PrimaryKey(autoGenerate = true)

    val uid: Int = 0,
    val str: String
)

@Dao
interface DataDao {
    @Query("SELECT * FROM data")
    fun getAll(): Flow<List<Data>>
}

When I include dataModel: DataModel = hiltViewModel() in a @Composable view, the app crashes. How can this be resolved?

Error messages:

Please edit the question to also provide AppDatabase and, most importantly, the full stacktrace of the error. Please also provide a primary key for Data. Apart from that, everything seems to work, the issue isn't reproducible. — tyg

There is an incompatibility in your stack trace: 1.8 vs 11. You should first fix that. This link might help. — Sempfer

The logs clearly say:

Execution failed for task ':app:kspDebugKotlin'.

Inconsistent JVM-target compatibility detected for tasks 'compileDebugJavaWithJavac' (1.8) and 'kspDebugKotlin' (11).

Add this to your build.gradle.kts:

kotlin {
    jvmToolchain(8) // or jvmToolchain(11)
}

compileDebugJavaWithJavac targets java 8 (that's the 1.8 in the log), while kspDebugKotlin targets java 11, hence the inconsistency seen in the logs.

After adding that I get another error: Could not determine the dependencies of task ':app:compileDebugKotlin'.
