- Eclipse is an open-source integrated development environment originally developed by IBM. It started in 2001 and was released as open source software. - The Eclipse platform consists of three main components: the runtime platform, the Java development toolkit (JDT), and the plug-in development environment. - Plugins can be used to extend Eclipse's functionality and are available through the Eclipse marketplace. Common plugins include support for web development, UML modeling, and log viewing.

3. O R I G I N S Version 1.0 – November, 2001 Serious usage started with version 3.0 IBM spent nearly $ 40 million on its development Object Technologies International [OTI] - IBM subsidiary – takes care of Eclipse development OTI developed VA4J [Visual Age] – re-written to emerge as Eclipse Released as Open Source – still is! Consists of 3 sub-projects: Platform , Java Development Toolkit , Plug-in Development

5. The P L A T F O R M Platform Runtime – discovers all installed plug-ins. Does NOT load them Workspace manages user’s resources in file-folder structure maintains low-level history of files notifies Tools about workspace changes Workbench – provides the graphical UI using SWT and JFace Team support – plug-in facility for version control Help – extensible documentation facility

6. Downloading E C L I P S E http://www.eclipse.org/downloads/ JRE 5.0+ will be required to run Eclipse Release version – thoroughly tested, major release Stable version – before release, undergoing testing, relatively stable Integration build – individual components are stable, but no guarantee on integrated behaviour Nightly build – built from the latest version of code Gives a feel of the latest/upcoming features

7. P L U G I N S Every component in the workbench is a plug-in Extend the feature set of Eclipse Examples – Web Toolkit Project [WTP], UML Designer, log4j viewer Plug-ins repository - http://www.eclipseplugincentral.com Can be installed in 2 ways – Through the IDE Manual installation

8. P L U G I N S - Installation Using the IDE Help >> Software Updates

9. P L U G I N S - Installation Using the IDE Existing plug-ins can be updated by clicking on ‘Update’ button there For a new plug-in, the repository site needs to be added Enter the URL for the plug-in repository/archive

10. P L U G I N S - Installation Download the plug-in archive [usually a ZIP file] Extract it – a ‘features’ and ‘plugins’ directory are present Go to the Eclipse installation directory Copy the contents of extracted ‘features’ and ‘plugins’ directory Launch Eclipse with the ‘- clean ’ flag

11. P E R S P E C T I V E S & V I E W S The many number of different types of panes – Views Pre-selected sets of views arranged in an order – Perspective User customised perspectives also possible Views Perspective

12. Creating – J A V A Standalone Project File >> New >> Java Project Either a new project content, or, existing content can be chosen Configure the JRE version to be used Enter a project name

13. Creating – J A V A Standalone Project If not selected, choose the Java perspective and Package Explorer view Default package structure with ‘src’ folder Default JAR’s imported from JRE Ctrl + N – get the new resource wizard Select a ‘class’ or ‘package’ to add

14. Creating – J A V A Web Project Ctrl + N – get the new resource wizard Select ‘Dynamic Web Project’ under ‘Web’ folder WTP plug-in should be installed! Other Web project artefacts can also be created later on

15. Creating – J A V A Web Project Enter a project name This will also be context root Web application server specified here Specify any of the default config presets WTP plug-in should be installed!

16. Creating – J A V A Web Project If not selected, choose the Java EE perspective and Package Explorer view Ctrl + N – get the new resource wizard Select a ‘class’ or ‘package’ to add Default package structure with ‘src’ and ‘WebContent’ folder. Default JAR’s imported from JRE

17. P R E F E R E N C E S Allows user to personalise and customise Fonts, colours, layout, formatting, behaviour, presets Can be saved and exported and shared Helps in getting a consistent look

18. P R E F E R E N C E S Java coding standards can be automatically enforced! Window >> Preferences >> Java >> Formatter, click on Edit Almost all aspects of code formatting like indentation, tab control, white-space control, etc
