Scripts to help migrate existing Gradle projects to Buck

This python script will take an existing Gradle project and generate a BUCK file per Java package, generating all dependencies for you.

This is a script I am hacking on and is likely not fit for external use.

First, you should build your project with Gradle to fetch all dependencies needed.

Optionally, use Android Studio's Optimize Imports feature to remove any unneeded dependencies between Java packages.

Buck encourages the creation of many small modules, ideally at the Java Package level. Buck, however, doesn't allow cyclic dependencies between modules. Thankfully, IntelliJ provides tools to tease these apart.

For advice on how to resolve cyclic dependencies, see the excellent series about F# - http://fsharpforfunandprofit.com/posts/cyclic-dependencies/. While these articles are about F#, the ideas are generally applicable.

Next, run python $PATH_TO_THIS_REPO/buck_file_generator.py

And all of your Java modules will have a BUCK file generated for them.
