This document provides an overview and agenda for a presentation on using Maven with AWS services like CodeCommit, CodeArtifact, and ECR. It discusses Maven concepts like folders, POMs, lifecycles, plugins and goals. It also covers setting up projects with these AWS services, performing Maven releases, and best practices. Example builds are provided like a Hello World app and utilizing services together.

● Folder structure
● Introduction of build lifecycle

5. Maven Folder structure

6. Walking with Maven POM.xml

8. Maven Lifecycle
● Packaging
● Phases
● Plugins
● Goals
● Dependency
● Profiles
● Distribution Management

10. Maven Packaging
● Various packaging types support
○ EJB, EJB3, JAR, EAR, PAR, RAR, WAR, POM, Maven-plugin
○ Custom Packaging type, i.e hpi (Jenkins plugin)
● Default Packaging type is JAR
● Packaging type enable various phases of build lifecycle phases

11. Maven Phase
● Maven lifecycle are based on the phase
● Phase associated with Plugin Goals
● Packaging type define lifecycle phases
● Phases named with hyphenated-words (pre-*, post-*, or process-*)

12. Maven Plugins and Goals
● Plugin is heart of Maven Build system
● Each Plugin provide one or more goals
● Goals are need to map with Phase to be executed
● Some plugin goal is pre mapped with phase

13. Maven Dependency and BOM
● Dependency management is a core feature of Maven
● Direct/Transitive Dependency
● Dependency scope (compile, Provided, Runtime, Test, System, Import)
● Bill of Materials (BOM)
○ A Collection of dependency
○ Best way to manage Dependency with in different project

14. Maven Profiles
● A set of Maven configuration
● Can be activated on demand or automaticaly
● Help to modularize Maven build process
● Define at
○ Per Project (pom.xml)
○ Per User (%USER_HOME%/.m2/settings.xml)
○ Per Global (${maven.home}/conf/settings.xml)

15. Maven Repository
● Central place to store and retrieve artifacts of dependency/plugins
● Artifact categorize as Snapshot or Release
● Local repository (~/.m2)
● Remote repository (https://repo.maven.apache.org)
● 3rd Party Repository proxy software
○ Sonatype Nexus
○ JFrog Artifactory
○ AWS CodeArtifact

16. Maven
Hello World!

17. AWS CodeCommit
● A Hosted Git repository service provided by AWS
● Access control setup using AWS IAM
● Easy to integrate with other AWS Services

18. AWS CodeArtifact
● A Hosted repository service provided by AWS
● Support Maven, NPM, PyPI..
● Access control setup using AWS IAM
● Easy to integrate with other AWS Services
● Securly access package with in VPC (VPC PrivateLink Endpoint)

19. AWS ECR
● A Hosted Container repository service provided by AWS
● Access control setup using AWS IAM
● Easy to integrate with other AWS Services
● Pull through cache repositories

20. AWS
CodeCommit,
CodeArtifact, ERC
Hello World!

21. Maven Release process
● Overview of Release process
● Maven Release process tasks
○ Project verification for ready to release.
○ Code tagging
○ Version management
○ Project building
○ Release artifact deployment to repository
○ Prepare for the next development version

22. Maven Release
process with AWS
CodeCommit,
CodeArtifact, ECR
Hello World!

23. Cool things I have build using Maven
● Count a total line of Code
○ github.com/AlDanial/cloc
● Software bill of material generation
○ CycloneDX (SBOM format)
● Dependency Track Integration
○ Continues vulnerability scanning and alerting
○ Software Supply chain attack
○ Open source license management with SPDX
● License Finder Integration
○ github.com/pivotal/LicenseFinder

25. List of cool Maven plugins
● Maven-antrun-plugin
● Maven-assembly-plugin
● Maven-enforcer-plugin
● Jib-maven-plugin
● Sql-maven-plugin
● Exec-maven-plugin
● Groovy-maven-plugin
● Cyclonedx-maven-plugin
● Spring-boot-maven-plugin

26. Maven Best practices
● Separate dependency and build lifecycle
● Increase usage of Maven Dependency BOM
● Use of Parent pom
● Add dependency management on parent pom for Multi Module project
● Always define version on plugins
● Make a use of Profile

27. Thanks!
