What automation system for build process have you used in practice?

In practice, the most commonly used systems for automating Java project builds are:

• Maven — a widely used tool that manages dependencies, compilation, testing, and packaging of the project. It uses a pom.xml file for configuration.
• Gradle — a more modern and flexible tool that uses scripts written in Groovy or Kotlin DSL. It allows for faster project builds and better integration with Android.

Example of a simple build.gradle file:

plugins {
    id 'java'
}

dependencies {
    implementation 'org.springframework:spring-core:5.3.9'
    testImplementation 'junit:junit:4.13.2'
}

repositories {
    mavenCentral()
}
