In their own words

Gradle

Gradle Build Tool is a free, open-source system for automating software builds across projects of different types and sizes. Build logic can use either Kotlin DSL or Groovy DSL. Incremental builds, caching and parallel task execution support the build process, while Gradle downloads and manages transitive dependencies from Maven- and Ivy-compatible repositories. The Gradle Wrapper can provision a build environment and specify the Gradle version used by a project. Its ecosystem covers JVM, Android, C/C++, Swift, Objective-C and assembler projects, and it runs on Windows, macOS and Linux. The Tooling API lets IDEs and other tools inspect projects, run builds, receive progress events and cancel operations. Listed support includes Android Studio and Ant, plus Checkstyle, CodeNarc, PMD and JaCoCo. Gradle includes dependency verification. The maker says open-source security fixes are limited by its end-of-life policy; its Security Subscription offers prioritized fixes under SLA and extended maintenance, but does not guarantee a clean scanner report when findings come from third-party libraries.
