- 5. Eclipse is written in Javain little pieces (plugins)
- 6. Mini-Agenda The Eclipse EcosystemEclipse and modularityEclipse Plugin and RCP developmentEclipse 4.0 / Eclipse e4
- 8. Successful Open Source Projects
- 9. Unlike other (successful) OpenSource Projects Eclipse has no mascotThis is NOT the animal representing Eclipse
- 10. ImpactEclipse – History BookVery disruptive for the pay IDE Eclipse is a vendor independent Open Source ProjectNov. 2001 – Code released as Open Source, still lead by companiesFebr. 2004 – Eclipse Foundation created
- 11. ImpactEclipse – History BookStart of Eclipse as a platform, e.g. NASA starts using Eclipse for it‘s Mars missionMarket leader with a strong ecosystemRe-gain innovation speedJuni 2004 – Eclipse 3.0 based on OSGi and enables Eclipse RCP 2010 - Current Eclipse 3.5.2 (aka Ganymede)06.2010 Release of Eclipse 3.607.2010 Planned first release of Eclipse 4.0
- 12. Eclipse Foundation The Eclipse Foundation is a not-for-profit, member supported corporation that hosts the Eclipse projects and helps cultivate both an open source community and an ecosystem of complementary products and services.
- 13. Eclipse Foundation does not pay developersMember companies and private persons develop the code
- 15. ALL MEMBERS

- 31. Each Plugin defines also its dependencies
- 32. Runtime (OSGi) makes sure the API contacts are fulfilled
- 33. Plugin and RCP Development
- 35. MANIFEST.MF – Defines OSGi bundleplugin.xml – Defines Eclipse extensions and extension pointsPDE (Plug-in Development Environement) provides editors for these files.Configuration files
- 36. Extensions Extension PointsProvide functionality to predefined slots (== extension points)Define places where others (== extensions) can provide functionality
- 37. Eclipse extensibility is a little bit like Emacs, you can add easily functionalityBut not in LISP
