1. A JJTV tool night presentation
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
 Maven home: http://maven.apache.org
 Central repository: http://search.maven.org
