## AI overview

The article describes a Gradle module convention that separates each feature's public API from its implementation. The author says this structure reduced build times and coupling between features while helping enforce test coverage, with Android Gradle Plugin support making a separate test-fixtures module unnecessary.

## Source excerpt

Flattening my Dependency Graph Jesse Wilson Jesse explores a Gradle module structure that he likes. Read now ➡ I liked this not-so-recent post from Jesse Wilson, which outlines a Gradle module convention that prioritizes clear public/private boundaries to support encapsulation and build speed. The approach, adapted from one presented by Ralf Wondratschek, also happens to closely resemble one that I helped institute at Dropbox shortly after I joined four and a half years ago.
