"Cannot solve symbol Properties" while migrating project

Hello everyone. I’m new here. I was migrating a project and was trying to set it up as best as I could but i get errors every now and then. But right now, I’m stuck here. Has anyone else also faced this problem? or does anyone know how to solve this?

Migrating from what to what?

You probably just miss the import for that class.

Btw. I strongly recommend switching to Kotlin DSL. It is the default DSL by now, you immediately get type-safe build scripts, actually helpful error messages if you mess up the syntax, and amazingly better IDE support if you use a good IDE like IntelliJ IDEA or Android Studio.
