Openfire SVN + Eclipse 3.3 + Subversive Installation Guide

Download JDK and install them. The least version should be 1.5. I use 1.6. Sorry, no instruction for this.

Download Eclipse 3.3 from www.eclipse.org. I use Eclipse IDE for Java EE Developers. You should at least use Eclipse IDE for Java Developers.
Extract the downloaded zip file into C:/Program Files/Eclipse.
Open C:/Program Files/Eclipse folder.
Right click and drag eclipse.exe on to your desktop (or Windows taskbar) to create a shortcut icon.
Right click the shortcut icon and choose Properties. The Eclipse Properties window will show.
The Target textbox should read something like this "C:\Program Files\Eclipse\eclipse.exe" -vm "C:\Program Files\Java\jdk1.6.0\bin\javaw" depending on the JDK that you use and where you installed it.
Close the Eclipse Properties window.

Double-click the shortcut icon to start Eclipse.
Select/enter your preferred workspace and click OK to open Eclipse main IDE window.
Click on the Workbench icon to close the welcome screen.
Click Help::Software Updates::Find and Install... menu.
Click on Search for new features to install and click Next.
Click on New Remote Site... button.
Enter Subversive in the Name box and http://www.polarion.org/projects/subversive/download/1.1/update-site in the URL box (Check the latest URL from http://www.eclipse.org/subversive website), then click OK.
Click Finish to install Subversive. Eclipse will search for the update site and show the result in a next window where you will select the features to install. I choose everything under Subversive SVN Team Provider Plugin and Subversive Client Libraries.
Click Next to continue and so on until the installation ends. You normally want to restart Eclipse when the installation ends.

Click Windows::Open Perspective::Other... menu.
Click on SVN Repository Exploring on the Open Perspective window and click OK.
Right-click on SVN Repositories screen and choose New::Repository Location...
On New Repository Location enter http://svn.igniterealtime.org/svn/repos in the URL box and click Finish. You'll see the URL location in the SVN Repositories screen.
Expand the URL location.
Expand the openfire tree.
Right-click on trunk and choose Check Out. Make yourself some Cafe-Latte while waiting for the checkout to complete.

Click Window::Open Perspective::Java menu.
In the Project Explorer screen, if there is an openfire project, delete it. This project was created during the Openfire check out process. Yes you read it correctly, DELETE the project!!! Otherwise you'll have to setup your Openfire development environment manually. On the Confirm Project Delete choose Do not delete contents, then click Yes.
Click File::New::Project... Notice the ellipses!!!
Select Java::Java Project and click Next.
On the New Java Project window choose Create project from existing source and browse to where openfire folder is located under your workspace.
In the Project name box enter exactly as openfire. Otherwise, the Next and Finish button remain disabled. Click on Next. Eclipse will read the directory structure to setup the environment automatically (almost) for you and you can see what it does on the next screen. Then click on Finish.
If the Open Associated Perspective windows opens, click Yes.

Click Window::Show View::Ant menu.
Right-click the Ant screen and choose Add Buildfiles...
Expand the openfire::build folder and select build.xml, then click OK.
On the Ant screen, expand the Openfire XMPP Server and double-click on openfire ant task. The build may fail because you're checking out the daily updates of Openfire sources, which may contain bugs. If so, wait for another day and hope that the developers discover and fix the bug; or you might dare to fix it yourself. During this first time setup, a successful build is necessary before you can proceed with the remaining tasks below.

Click Run::Open Run Dialog... or Run::Open Debug Dialog... menu. A Run window shows.
Select Java Application and click on the New button.
On the Main tab of the Run window, change the New_configuration name to Openfire or anything you like.
Click on Project::Browse button and select openfire and click OK.
Click on Main class::Search button and select ServerStarter - org.jivesoftware.openfire.starter and click OK.
I'd suggest that you select Stop in main check box so that you could later verify that debugging works.
Click on the Arguments tab.
Enter -DopenfireHome="${workspace_loc:openfire}/target/openfire" in the VM arguments box.
Click on Classpath tab.
Select User Entries so that the Advanced... button will be enabled.
Click on the Advanced... button.
On the Advanced Options window select Add Folders and click OK.
On the Folder Selection window select openfire::src::i18n folder and click OK.
Click on the Advanced... and Add Folders buttons once again to include openfire::src::resources::jar folder.
Click on the Advanced... and Add Folders buttons once again to include openfire::build::lib::dist folder.
Click on Common tab.
Select the Debug and Run check box.
Click on Apply button.
Click on Close button.

The setting is now complete for Openfire.
You may test running and debugging by clicking on Run::Run History::Openfire and Run::Debug History::Openfire respectively. If you choose the later and if you follow this instruction closely, execution will stop on the main method in ServerStarter.java.
