.gradle File — Gradle Build Script

Gradle build scripts define project build configurations using a Groovy or Kotlin DSL (Domain Specific Language). Gradle is the default build system for Android applications and is widely used for Java, Kotlin, Scala, and Groovy projects. GRADLE files (typically build.gradle for Groovy or build.gradle.kts for Kotlin) define dependencies, plugins, tasks, source sets, compile options, and publishing configurations. Gradle combines the declarative dependency management of Maven with the flexibility of Ant's imperative scripting, providing a powerful and expressive build system. Key features include incremental compilation, build caching (including distributed cache), parallel execution, composite builds, and the Gradle Wrapper (gradlew) that ensures consistent Gradle versions across development environments. The dependency management system resolves transitive dependencies from Maven Central, Google's Maven repository, and custom repositories. Gradle's task graph model determines execution order and enables optimization through up-to-date checking and task avoidance. The Android Gradle Plugin extends Gradle with Android-specific build features including APK/AAB packaging, ProGuard/R8 code shrinking, build variants, and resource processing.
