• Centralized version management for dependencies and plugins
• Pre-configured build plugins with sensible defaults
• Support for modern Java development tools and frameworks
• Cloud-native development support (GCP, AWS)
• Database migration and testing utilities

• Development: Version management, source attachment

Benefits of Using as Parent Project

1. Centralized Version Management

<parent>
    <groupId>org.metalib.maven.pom</groupId>
    <artifactId>metalib-spring-pom</artifactId>
    <version>0.0.71-SNAPSHOT</version>
</parent>

All dependency versions are managed centrally, ensuring consistency across projects and eliminating version conflicts.

2. Shared Dependencies

The parent POM provides automatic inclusion of essential dependencies:

• Lombok: Reduces boilerplate code with annotations
• MapStruct: Type-safe bean mapping
• Spring Boot: Complete framework stack through BOM imports

3. Pre-configured Plugins

• Maven Compiler Plugin: Configured with Java 21 and annotation processors
• Surefire/Failsafe: Ready for unit and integration testing
• Enforcer Plugin: Ensures Maven version compliance
• Release Plugin: Streamlined release process with semantic versioning

5. Cloud-Native Ready

• Google Cloud Platform libraries BOM
• AWS SDK BOM
• Docker Maven plugin integration
• Secret management utilities

Maven Properties Management

The parent POM provides extensive property management for versions:

Dependency Version Commands

# Check for dependency updates
mvn versions:display-dependency-updates

# Check for plugin updates  
mvn versions:display-plugin-updates

# Check for property updates
mvn versions:display-property-updates
