Maven vs Gradle: key differences and when to choose each

Teams switching between projects face friction when one uses Maven (pom.xml) and another uses Gradle (build.gradle). Understanding the core trade-offs helps make an informed choice and avoid common pitfalls in each.

Key differences and guidance:

Maven:

• Declarative XML with a fixed lifecycle (compile → test → package → install → deploy)
• Convention-over-configuration — deviating requires plugins
• Mature ecosystem, every tool integrates with Maven first
• Reproducible builds by default

<!-- pom.xml dependency -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>

Gradle:

• Groovy/Kotlin DSL with flexible task graph
• Incremental builds and build caching are first-class — faster in large projects
• Better suited for multi-module projects with complex interdependencies
• Learning curve is steeper

// build.gradle.kts
dependencies {
    implementation("org.springframework.boot:spring-boot-starter-web")
    testImplementation("org.springframework.boot:spring-boot-starter-test")
}

Choose Maven for standard Spring Boot apps with simple requirements. Choose Gradle for large monorepos, Android projects, or when build performance is critical.

Maven's fixed lifecycle and XML verbosity trade flexibility for predictability. Gradle's dynamic task graph enables optimization at the cost of complexity. Spring Initializr supports both equally.
