Question 1

How does Gradle handle dependency resolution conflicts, especially with transitive dependencies?

Accepted Answer

Gradle employs a sophisticated dependency resolution engine that prioritizes the highest version by default. You can explicitly declare `resolutionStrategy` blocks in your `build.gradle` to force specific versions, exclude transitive dependencies, or define custom conflict resolution rules, all detailed in the dependency management section of the official documentation.

Question 2

Is there an official way to analyze build performance and identify bottlenecks?

Accepted Answer

Yes, Gradle offers the Build Scan service. By adding `--scan` to your command line, Gradle generates a detailed, shareable report on `scans.gradle.com` that visualizes task execution times, dependency graphs, and configuration issues, providing deep insights into build performance.

Question 3

What are the key differences and advantages of using the Kotlin DSL over Groovy for build scripts?

Accepted Answer

The Kotlin DSL (Domain Specific Language) offers compile-time safety, better IDE support (autocompletion, refactoring), and a more idiomatic Kotlin experience, reducing common scripting errors. While Groovy DSL is still fully supported, Kotlin DSL is generally recommended for new projects due to its enhanced developer experience and robustness.

Question 4

How can I ensure my Gradle builds are reproducible across different developer machines and CI environments?

Accepted Answer

To ensure reproducibility, always specify exact dependency versions, use the Gradle Wrapper (`gradlew`) to standardize the Gradle version, and configure dependency caches appropriately. The documentation provides guidelines on `build-cache` setup and `checksum` verification for downloaded artifacts to minimize environmental variances.

Question 5

What is the recommended approach for managing custom plugins or shared build logic across multiple internal projects?

Accepted Answer

For internal shared logic, you can create composite builds, convention plugins (precompiled script plugins), or publish custom plugins to a private Maven repository. The Gradle documentation offers detailed guides on structuring multi-project builds and developing custom plugins to encapsulate and reuse build logic effectively.
