Have you used the Gradle build system in your projects?

Yes, I have used Gradle in several Java projects for build automation, dependency management, and running tests. Gradle allows flexible customization of the build process using scripts in Groovy or Kotlin DSL.

Example of a simple build.gradle file:

plugins {
    id 'java'
}

group 'com.example'
version '1.0-SNAPSHOT'

repositories {
    mavenCentral()
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter'
    testImplementation 'junit:junit:4.13.2'
}

// Task to run the application

jar {
    manifest {
        attributes 'Main-Class': 'com.example.Main'
    }
}

Gradle is suitable for projects of various sizes, supports caching, incremental builds, and integration with CI/CD.
