'@HiltViewModel annotated class should contain exactly one @Inject annotated constructor

I keep getting this error:

public final class MainViewModel extends androidx.lifecycle.ViewModel { ^ @HiltViewModel annotated class should contain exactly one @Inject annotated constructor. [Hilt] Processing did not complete. See error above for details.

Here is my MainViewModel:

@HiltViewModel
class MainViewModel @Inject constructor(
    repository: DefaultRepository
) : ViewModel() {
    val items = repository.getItems().asLiveData()
}

android dagger-hilt

In my case, I was specifying default values for some of my primary constructor parameters. Getting rid of the default values fixed the issue.

Make sure you are using this inject annotation

import javax.inject.Inject

instead of this one

com.google.inject.Inject

Solution 3:^[3]

Make sure in your module you have @InstallIn(SingletonComponent::class) instead of @InstallIn(ApplicationComponentManager::class)

Solution 4:^[4]

In my case the problem was that one of the packages was called "case", which is a name used by some conventions (like of SQL, or even Java).

@Atick Faisal (see comments above) had also another problem with package name, so I guess it might worth a check if you don't find the problem.
