Explore Gradle's Composite Build feature in this 27-minute Devoxx conference talk. Learn how to combine multiple independent Gradle builds into a single project, automatically replace binary dependencies with project dependencies, and make changes to upstream components immediately visible to dependents. Discover how to import composite builds into IDEs, work on them as a single codebase, and simplify the process of splitting large mono-repos into smaller, manageable parts. Gain insights into composing builds dynamically using Gradle's rich DSL, and understand how this feature can improve your development workflow. The talk covers various aspects including dependencies, IDE integration (Eclipse and IntelliJ), mono-repo management, plugin development, and build optimization. Presented by Sterling Greene, a core developer for the Gradle build tool, this talk also addresses limitations and includes a Q&A session.
