Maven FlexPack Support with Build Info Collection and Artifact Property Setting

Overview

This PR implements comprehensive Maven FlexPack support in jfrog-cli-artifactory, enabling native Maven execution with complete build info collection, deployed artifact tracking, and build property setting. The implementation follows the established Poetry FlexPack pattern for consistency and maintainability.

Key Features

🚀 Native Maven Execution

• Execute Maven commands natively with JFROG_RUN_NATIVE=true
• Seamless integration with existing JFrog CLI workflows
• Full compatibility with standard Maven commands (compile, install, deploy, etc.)

📊 Complete Build Info Collection

• Dependencies: Collects all Maven dependencies with proper scopes (compile, runtime, test, provided, system, import)
• Checksums: Calculates MD5, SHA1, and SHA256 checksums for all dependencies
• Artifacts: Includes deployed JAR and POM artifacts in build info
• Metadata: Captures Maven coordinates, versions, and dependency relationships

🏷️ Build Property Setting

• Automatically sets build.name, build.number, and build.project properties on deployed artifacts
• Only executes for deploy commands (not compile, install, etc.)
• Follows the same pattern as Twine for consistency
• Enables artifact traceability and build correlation

🔄 Build Info Publishing

• Saves build info in format compatible with jf rt bp
• Maintains consistency with existing build info structure
• Supports project-based build info organization

Implementation Details

Architecture

The implementation follows the Poetry FlexPack pattern exactly:

Maven Pattern (New):
jf mvn deploy --build-name=test --build-number=1
├── buildtools/cli.go → MavenCmd()
├── maven/maven.go → Run()
└── flexpack.NewMavenFlexPack() → CollectBuildInfo()

File Structure

jfrog-cli-artifactory/
└── artifactory/commands/flexpack/
└── maven.go (280 lines) - Essential Maven FlexPack functionality

Usage Examples

Basic Maven Deploy with Build Info

export JFROG_RUN_NATIVE=true
jf mvn deploy --build-name=my-maven-build --build-number=1
jf rt bp my-maven-build 1

Maven Install (No Deployment)

export JFROG_RUN_NATIVE=true
jf mvn install --build-name=my-maven-build --build-number=1
# Only dependencies collected, no artifacts or properties set
