This talk presents part 1 of "MuleSoft, Maven and Managing Dependencies". It will provide the basic foundation of Maven in MuleSoft and its use in our day-to-day development lifecycle. We will learn to work with Maven, POM, and Super POM. We will also study how Maven is helping us manage dependencies with ease. This talk will have a basic POM demo. Part 1 Topics: What is Maven? Maven's Objectives Installation Embedded Maven in Studio What does Maven do?

9. MuleSoft, Maven and Managing Dependencies
(Part 1: Basics)

10. 10
● Maven is a tool that can be used for building and managing any
Java-based project
What is Maven?

11. 11
● Make the build process easy
● Provide a uniform build system
● Provide quality project information
● Encourage better development practices
Maven’s Objectives

12. 12
● Yes
● No
Do we need to install Maven while working with
MuleSoft?

13. 13
Where is Maven in Anypoint Studio?

14. 14
● Download:
https://maven.apache.org/download.cgi
● Install:
https://maven.apache.org/install.html
Still want to install it locally?

15. 15
● It builds your application (along with necessary details) by following
the build lifecycle
What does Maven actually do?

16. 16
● Clean : Project Cleaning
● Site : Project Website
● Default : Project Deployment
Build Lifecycle

17. 17
● Cleans the project
● Removes all build artifacts from working directory
Clean Lifecycle

18. 18
● Creates the website for your project
Site Lifecycle

19. 19
● validate : validate the project is correct and all necessary
information is available
● compile : compile the source code of the project
Default Lifecycle Phases

20. 20
● test : test the compiled source code using a suitable unit
testing framework. These tests should not require
the code be packaged or deployed
● package : take the compiled code and package it in its
distributable format, such as a JAR
Default Lifecycle Phases

21. 21
● verify : run any checks on results of integration tests to
ensure quality criteria are met
● install : install the package into the local repository, for use
as a dependency in other projects locally
Default Lifecycle Phases

22. 22
● deploy : done in the build environment, copies the final
package to the remote repository for sharing with
other developers and projects.

26. 26
● POM
How is Maven achieving all this?

27. 27
● POM is a fundamental unit of work in Maven
● It is an XML file that contains information about the project and
configuration details used by Maven to build the project
Project Object Model

28. 28
● project – root
● modelVersion – should be set to 4.0.0
● groupId – the id of the project’s group
● artifactId – the id of the artifact (project)
● version – the version of the artifact under the specified group
Minimal POM

29. 29
<project>
<modelVersion>4.0.0</modelVersion>
<groupId>com.mycompany.app</groupId>
<artifactId>my-app</artifactId>
<version>1</version>
</project>
Example of Minimal POM

30. 30
Mule Project POM

31. 31
● All models implicitly inherit from a super-POM

pom.html

application
● It has below advantages
○ Reduce redundancy
○ Minimize conflicting versions
○ Streamline dependency upgrade process
