Description

Databinding has a CLI compiler that is in aosp (no artifact on maven.google.com yet). It is only two classes, but it allows ingesting layout xml files and outputting the metadata required by the databinding annotation processor to work correctly.

By using a genrule to pre-process the resources of a module, databinding support can be added in buck/okbuck

Research direction
Start by examining the referenced Android databinding CLI compiler at the provided AOSP link. Understand how genrules work in Buck to pre process resources. Look at existing OkBuck plugins for similar genrule integrations. No linked PRs or comments suggest ongoing work, so this is open for implementation. The main challenge is integrating the compiler output with the annotation processor.
