Gradle is the newest addition to the Java build project automation tool family. It is open sourced under Apache License 2.0 and its first version (0.7) was released in 2009. Gradle has been gaining a lot of adoption as it draws on lessons learned from other existing build tools such as Ant and Maven. Several high-profile projects such as Android, Spring Framework, and Hibernate have migrated their build systems to use Gradle.
Gradle Features:
- Declarative Dependency Management
- Declarative Builds
- Build by Convention
- Incremental Builds
- Gradle Wrapper
- Plugins
- Open Source
