Setting up the environment

These are the steps I took to have my environment ready for coding.

  1. At first you need to checkout the subclipse code. Here you’ll find instructions about accesing the source code repository. Use ‘guest‘ for username and password.
  2. Make a clean installation of eclipse. Since sublicpse is a plugin for Eclipse I downloaded Eclipse Europa for RCP/Plug-in Developers.
  3. Sublicpse itself is also needed.  So install it.
  4. Import the projects under trunk/subclipse with File -> Import… -> General / Existing Projects into Workspace. Then choose the trunk/subclipse folder.
  5. The build of the project org.tigris.subversion.clientadapter.svnkit will fail, but it doesn’t matter. SVNKit is pure Java library for accessing SVN repositories. By default (at least in Windows) JavaHL is used instead. You can change this in the preferences page: Window -> Preferences -> Team / SVN.

Once I set up the environment I made some changes in the source code and I tested it. I think the easiest change is adding a component in the preferences page. The source code for the preferences page can be found in the org.tigris.subversion.subclipse.ui.preferences.SVNPreferencesPage class. I added the second line in this example code:

showCompareRevisionInDialog = createCheckBox(composite, Policy.bind("SVNPreferencePage.showCompareMergeInSync"));
createCheckBox(composite, "foo bar");

Now you need to test that this code works. To do this open the plugin descriptor file (plugin.xml) for the org.tigris.subversion.subclipse.ui project. You’ll see an editor pane with many tabs at the bottom. In the default tab (Overview) there are two options for Testing: “Launch an Eclipse application” and “Launch an Eclipse application in Debug mode”. Click one of them. A new Eclipse application will be launched with your code changes. Now open the SVN Prefrences Page to see the changes.
