Kotlin Extensions - Synthetic imports show compilation error in child class

Question

I have a class A where my view fragment_my_quests is defined. Synthetic imports works fine in class A. Now I extend B with A and try to use Synthetic import and id's inside my child class B. It shows red (compilation error). But when I run the app, it works fine. Just the compiler is not able to understand this. I am attaching screenshots for the reference.

Koltlin version : 1.3.20 Anko version : 0.10.8 Gradle version : 3.3.0

This is the screenshot for parent class. Synthetic imports works fine and do not show any compilation error.

This is the screenshot for child class. Synthetic imports and the id's used in child class shows red.

try importing `kotlinx.android.synthetic.main.fragment_my_quests.view.*` — Jeel Vankhede, Feb 13 '19 at 04:59
Hi, maybe trying restarting android studio invalidating its caches and then resyncking the project with the gradle files again would remove the error? — Francislainy Campos, Feb 13 '19 at 06:39
Have tried restarting, invalidating cache, deleting gradle, rebuilding. Doesn't work — Harsh, Feb 13 '19 at 10:08
https://youtrack.jetbrains.com/issue/KT-22430, it's still an issue. You may use ButterKnife extension to overcome Synthetic Imports Error. — Renaissance, Feb 18 '19 at 21:29

Try as follows

Menu > File > Invalidate Caches / Restart
Build -> Clean Project
Tools -> Android -> Sync Project with Gradle Files

If not work then delete the ./gradle directory and import your project again try above 3 steps.
