Gradle is a build tool used primarily for Java projects. It automates the tasks such as compilation, packaging to testing, deployment, and publishing in the software development process.
Gradle combines the features of Apache Ant and Apache Maven. Instead of using XML-based project configuration which is used by Maven, Gradle uses Groovy & Kotlin based domain-specific language.
