Android Studio 3.x: error: cannot find symbol class GlideApp

Question

I updated Android Studio from 2.x to 3.x last week end. The project migration was perfect, build was great. And now, from 2 hours, I can't explain why, I can't build, I have this error on Glide now:

Error:(26, 22) error: cannot find symbol class GlideApp

All was good before, I didn't change anything (gradle or configuration), and now this error appears...

For information about Glide, in my Gradle:

annotationProcessor 'com.github.bumptech.glide:compiler:4.0.0-RC1'
compile 'com.github.bumptech.glide:glide:4.0.0-RC1'
compile 'com.github.bumptech.glide:okhttp3-integration:4.0.0-RC1'

The GlideApp file is generated automatically (I checked it).

So, it's a crazy situation. Thank you very much guys!

This also happens when you have another error in your code. Gradle doesn't get to generate Glide classes since another error is thrown before it
