I'm trying to configure the build.grade to use Room
The error persists:
Unresolved reference: room
And, consequently, the anotation remains Unresolved
@Entity
After 7 tutorials and 3 days, I have to surrender and ask for help.
Here I paste my build.grade. I've got it from this google tutorial:
https://developer.android.com/codelabs/android-room-with-a-view-kotlin#3
Which, by the way, is completely diferent from this other google tutorial:
https://developer.android.com/training/data-storage/room
What am I doing wrong?

Thanks to Mike T and Dkathayat1, it worked. I had to set the correct versions.
The code is the folowing:
