The document presents an overview of Maven, emphasizing it as a lifecycle management tool rather than just a build system. It discusses its key features such as being declarative, modular, and using XML for configuration, along with the importance of simplicity and conventions in its setup. Additionally, it provides links for further resources and the author's contact information.

Tomer Gabel, November 2012

2.  Maven is not news…
 … but it’s not well-understood either
 Let’s go back to basics

3.  A lifecycle management tool
 Not just a build system
 Declarative
 Not a script!
 Modular
 Everything is a plugin

4. Phases Goals
• process-resources
compile • compile resources:resources compiler:compile
• process-test-resources
test • test-compile
• test
package • prepare-package resources:test- compiler:test-
• package
resources compile
• verify
deploy • install
• deploy
surefire:test war:war

5. Hierarchy
POM
Dependencies Configuration

6.  XML
 *sigh* … yeah
 Artifact descriptor
 Hierarchy
 Dependencies

7.  POMs reference POMs
 Group, artifact, version
 Repository lookup
 Local repository
(“cache”)
 Remote repositories

8.  Convention over configuration
 Stick to the conventions if possible
 Keep it simple
 Avoid complex setups (e.g. multiple repositories)
 Avoid feature creep (stick to common plugins)

9.  Useful links
