Welcome to this guide on how to install and use Buck, a powerful build tool designed to optimize your development process. Though the original Buck system is effectively dead, we will walk through the basics of using it and its replacement, Buck2. Buck is known for its efficiency in building large codebases, and understanding it can be a big asset in your software development journey.

Installation Steps

The installation of Buck involves a two-phase bootstrapping process. Remember, you’ll need Java 8 or 11 for the compilation process.

Phase 1: Clone and Bootstrap

• First, you need to clone the Buck repository:

git clone --depth 1 https://github.com/facebook/buck.git

• Navigate into the cloned directory:

cd buck

• Next, bootstrap the build using Ant:

ant

Make sure your JAVA_HOME environment variable points to the correct Java version to avoid compilation errors.

Phase 2: Build Buck with Bootstrapped Version

• Now that you have bootstrapped Buck, you can build it using:

./bin/buck build --show-output buck

• The output will contain paths like:

# programs:buck buck-out/gen/programs/buck.pex

• To see help on the built program, run:

buck-out/gen/programs/buck.pex --help

Using Prebuilt Buck Binaries

If you prefer not to build Buck from source, you can download pre-built binaries directly:

• You can find binaries for any Buck SHA at jitpack.io.
• To fetch binaries specifically built for JDK 11, ensure you modify the URL to this format: jitpack.io/com/github/facebook/buck/shabuck-sha-java11.pex.

Understanding Feature Deprecation in Buck

The Buck team understands that keeping features up-to-date is essential. They have a process for deprecating features gracefully:

• When a feature is to be deprecated, an issue is created on GitHub detailing the change.
• Configuration flags are used to toggle the new and old behaviors until they transition fully.
• A removal date is established once a feature is deprecated, ensuring developers are well-informed.

Troubleshooting

If you encounter issues during installation:

• Ensure your Java version matches what Buck requires (Java 8 or 11).
• Double-check that your JAVA_HOME environment variable is correctly set.
• If you experience issues with ant, consider running it with increased verbosity to catch hidden errors.
