Glide: error: cannot find symbol class GlideApp

[MuruganSKutty]

Glide Version: 4.8.0

```

I'm using Android studio 3.5,

I have tried every solution found on forums but nothing seems to work. I have tried:

Cleaning / Rebuilding the project -> not working
Invalidate Caches -> not working

My MyAppGlideModule.java:

package com.example.balulu.models;

import com.bumptech.glide.annotation.GlideModule;
import com.bumptech.glide.module.AppGlideModule;

@GlideModule
public class MyAppGlideModule extends AppGlideModule {
// empty
}

Dependencies used:

implementation 'com.github.bumptech.glide:glide:4.8.0'
annotationProcessor 'com.github.bumptech.glide:compiler:4.8.0'

I found a solution myself. This error did not belong to Glide, it was related to ButterKnife library whenever we missed some view id in XML and keep calling that id in java file has produced this issue, so please make sure to use the correct view id mentioned in XML.
