What are the best practices for using Gradle in multi-module projects?

When working with multi-module projects in Gradle, it's essential to keep your modules cohesive and focused. Here are some best practices:

1. Define clear module boundaries: Each module should have a specific responsibility.
2. Use a shared build script: Centralize common configurations in a root build.gradle file.
3. Leverage dependency management: Use implementation and api configurations wisely to manage dependencies.
4. Keep modules independent: Avoid tight coupling between modules to enhance reusability.
5. Use version catalogs: Manage dependencies versions in a centralized way for consistency.

How can I structure my modules effectively?

A good structure often follows a layered approach. For example:

• Core Module: Contains shared logic and utilities.
• Feature Modules: Each feature of your application can be a separate module.
• App Module: The main application module that ties everything together. This way, you can develop and test features independently.

What should I avoid when setting up multi-module projects?

Avoid the following pitfalls:

1. Overlapping dependencies: This can lead to version conflicts.
2. Tight coupling: Modules should be loosely coupled to maintain flexibility.
3. Neglecting documentation: Ensure each module is well-documented for easier onboarding.

Can you give an example of a good module naming convention?

Sure! A common convention is to use a prefix that indicates the module's purpose, such as:

• app- for application modules (e.g., app-feature-login)
• lib- for library modules (e.g., lib-networking) This helps in quickly identifying the module's role within the project.
