Android - Kotlin - cannot find symbol DataBindingComponent

Issue

I'm facing this kind of phantom error. I've tried many ways to resolve this problem but nothing works. I don't know what produces this issue. This is my error in Build Log :

I don't know what's wrong, but when I try to access the variable that I've created in xml via binding.name_of_variable, it says: cannot access class check, your module classpath for missing or conflicting dependencies.

Solution

Try Invalidate Caches/Restart.. in Android Studio.

Select and click Files->Invalidate Caches/Restart.. .

This will regenerate the required ones.
