Open Source Project Management

1
Open Source Project Management

• Werner Keil Creative Arts Technologies

2
Presentation Goal
Learn how to use Open Source and Commercial
Tools together

• Build vs. Project Management
• Project Models and Dependencies
• Repositories
• IDE Integration
• Multiple Projects
• Project Lifecycle
• Continuous Integration

3
Build Tools History

• Make, GnuMake, MMake, NMake
• Jam
• Perl/Shell scripts
• Other scripts
• Platform-dependant
• Shell-based
• Sensitive to content format and changes

4
The Antcestor

• Apache Ant
• Platform-neutral
• Java-based
• XML content
• Most common build tool for Java and Web
• Usually for single projects(except more complex
  Ant-based frameworks)

A Sample Ant Target
vs. Maven goal
lt!-- compile Java source files --gt lttarget name
"compile"gt ltjavac srcdir "./src./test"

compile in M2)

POM

• Project Object Model
• Defines key elements of a project
• XML content
• Assisted by properties and scripts
• Jelly (languages in M2)
• Optional rich content via XDoclet
• Multiple formats in M2 (e.g. Wiki-like style)

POM Elements
Custom Settings (project.properties)
9
Dependencies

• Projects can share dependencies to ensure that
  every project re-uses common jar files.
• Avoid JAR Hell
• Dependency Management Tools
• Maven
• Ivy
• Commercial Systems

10
Repository

• Retrieved from a repository,
• Folder on a remote Web server containing all jar
  files
• By default, Maven uses http//www.ibiblio.org/mav
  en as its repository. /maven2 for M2
