Convert Maven pom.properties to JSON

Maven Properties Files

Maven generates pom.properties files inside built artifacts (JARs, WARs) containing metadata about the build. Additionally, Maven projects can define custom properties files for version management and plugin configuration.

Example pom.properties

# Auto-generated by Maven
groupId=com.example
artifactId=my-service
version=3.2.1
build.timestamp=2024-12-01T10:30:00Z

# Custom build properties
project.build.sourceEncoding=UTF-8
maven.compiler.source=17
maven.compiler.target=17
maven.compiler.release=17

# Dependency versions
spring-boot.version=3.2.0
jackson.version=2.16.1
lombok.version=1.18.30
junit.version=5.10.1

JSON Output

{
  "groupId": "com.example",
  "artifactId": "my-service",
  "version": "3.2.1",
  "build": {
    "timestamp": "2024-12-01T10:30:00Z"
  },
  "project": {
    "build": {
      "sourceEncoding": "UTF-8"
    }
  },
  "maven": {
    "compiler": {
      "source": 17,
      "target": 17,
      "release": 17
    }
  }
}

Use Cases

The JSON output is useful for:

• Build metadata APIs: Expose build info as a JSON endpoint (/actuator/info in Spring Boot)
• Dependency management dashboards: Parse version information for automated dependency tracking
• CI/CD pipelines: Extract artifact coordinates (groupId, artifactId, version) for deployment scripts
• Bill of Materials (BOM): Generate dependency inventories in JSON format for security scanning
