Downloading Anko AAR files

Hi, I am sorry if this isn’t the right place. We have a lots of Anko code in our project and it slows down the build a lot due to Jetifier. I am trying to download all the Anko AAR files and run ./jetifier-standalone on them. However, the GridLayout and ConstraintLayout are not downloadable.

The Issues · Kotlin/anko · GitHub is already archived and I can no longer post a question there. Please let me know if there is a way for me to get the two AAR files.
