Gradle open source build automation system builds upon the concepts of Apache Ant and Apache Maven introduces a Groovy-based domain-specific language (DSL)

Why gradle? Designed for multi-project builds which can grow to be quite large Supports incremental builds Tracks version upgrades

Polyglot builds Linkedin uses Gradle to build 60 different programming languages

Tool integrations

Robust Dependency Management Retrieve artifacts from any known binary repository, from public to private to local. Flat

High Performance Builds Gradle avoids unnecessary workload by caching: remote metadata and artifacts transitive dependency resolution build execution plan plugin inputs and outputs test results

Packs all the gear to build enterprise software for the JVM Test frameworks: JUnit, TestNG, Spock Application frameworks: Java EE, Grails, Play!, Code analysis cops: Checkstyle, CodeNarc, FindBugs, JDepend, PMD, JaCoCo, Sonar

Reliable incremental builds

Partial builds Gradle helps quickly accomplish the task by only building parts of the project

Efficient test execution Filter tests by type, group or pattern Run a single test Rerun failed tests Fail fast (stop on first failure) Run tests in parallel Distribute tests across multiple runtimes or machines Skip tests when not needed

Gradle’s Daemon cuts startup time to near zero enhances incremental builds reuses the execution plan between subsequent builds monitors changes to make builds reactive lets you move seamlessly between the IDE and command line performs preemptive work and maintenance tasks

From continuous integration to delivery Get feedback sooner thanks to CI job caching and Gradle’s incremental build capabilities. Activate Gradle’s numerous reports to inspect build results, troubleshoot problems and monitor build performance. Use Gradle’s publishing tasks to turn the CI server into a publishing tool and release manager. Push artifacts to a binary repository, documentation to a web server or your app to a staging or production environment.

Semantic Versioning v3.10.672 MAJOR version when you make incompatible API changes, MINOR version when you add functionality in a backwards-compatible manner, and PATCH version when you make backwards-compatible bug fixes.
