Gradle
  • It is a build automation system that uses a Groovy-based DSL (domain-specific language )
  • It does not use an XML file for declaring the project configuration.
  • It is based on a graph of task dependencies that do the work.
  • In Gradle, the main goal is to add functionality to the project.
  • It avoids the work by tracking input and output tasks and only runs the tasks that have been changed. Therefore it gives a faster performance.
  • Gradle is highly customizable; it provides a wide range of IDE support custom builds.
  • Gradle avoids the compilation of Java.
