Ok so what it looks like - did you sync only the device trees and any common ones and then use the "brunch" or "breakfast" command to download the rest of the repos. If so, then it's still pulled the repos from lineage (in all the dependency files, you can see where they come from)
If you did, try finding the AEX equivalent repo and replacing that in the .dependency file that it is referred to in.
If this is not what you did, please detail what you did to get your environment
That gave me that compiling error.
