Q:

Project build failed after migrate to AndroidX

My project can't build after I migrate to AndroidX, the error log show error: package android.support.annotation does not exist in some class, but these class can't be edited, when I edit these class and rebuild, these will be recovered.  When open these class will show Files under the "build" folder are generated and should not be edited.  and when edit these class will show  Generated source files should not be edited.  The change will be lost when sources are regenerated. 
I try to clean my project then sync and rebuild, but didn't work, how can I fixed that, thank you. 
Here is my error log:

Here is my gradle.properties:

A:

I think it have a problem with Glide Library.  
Can you just delete this part?  annotationProcessor 'com.github.bumptech.glide:compiler:4.9.0'
After that you should click Refactor -> Migrate to AndroidX
