If you have the git commad line tools installed (Ubuntu: sudo apt-get git-core) you can use the following command to check these repositories out from the command line:

git clone url

for example to get the JFace snippets use the following command.

git clone git://dev.eclipse.org/org.eclipse.jface/org.eclipse.jface.snippets.git

After that checkout you can import the project into Eclipse via File -> Import -> General -> Existing Project into Workspace.

Of course you can use the EGit plugin to checkout Git repositories directly in Eclipse. Check the excellent EGit User Guide for this.

Via Git we have another nice option to get the Eclipse source code in additon to cvs and svn.

I believe Git does currently not support Project Set Files (.psf) similar to cvs to get a consistent set of plugins but at least individual plugins can be checked out.

Update I have created a small introduction to Git Git Tutorial and to EGit Git with Eclipse – EGit Tutorial. Hope this helps.

In this second part of my 7 Paper Cuts in Eclipse I want to change some standard Eclipse code.

This second papercut is a bit more complex as the first papercut; I’m planning to return to simpler examples in the next papercut.

So lets define the papercut:

I frequently create example projects which I share in a svn repository. For related projects I use the mulitproject layout. The standard in subversion is “Simple Mode – One project for one repository”. Therefore everytime I share a project I have to switch in the subversion dialog from “Simple Mode” to “Advanced Mode”.

Nothing big? I agree, hence the perfect example for a papercut.

To change the coding of this dialog we need to find the class which is responsible to display this page. Plug-in Spy make this easy via Alt + Shift + F1.

Now you need to download the source code of the plug-in ”
org.eclipse.team.svn.ui”. This plug-in is stored in svn and can get access via subversion itself. The URL for the subversion repository view is: “http://dev.eclipse.org/svnroot/technology/org.eclipse.subversive”. See here to learn how to use svn and cvs to access the Eclipse code

Add this repository in the “SVN Repository” view and check-out (download) the plug-ins ”
org.eclipse.team.svn.ui” and “org.eclipse.team.svn.core”. You find them in “trunk”.

Looking at the coding of SelectProjectNamePage.java changing the selection only requires a few lines to be changed.

I use Eclipse Preferences to remember the last user selection.

protected SelectProjectNamePageSimpleModeComposite simpleModeComposite;
	protected ShareProjectNameAdvancedModeComposite advancedModeComposite;
	private static String SELECTION_MODE = "isSimpleMode";

	public SelectProjectNamePage() {
		super(
			SelectProjectNamePage.class.getName(),
			"",  //$NON-NLS-1$
			SVNTeamUIPlugin.instance().getImageDescriptor("icons/wizards/newconnect.gif")); //$NON-NLS-1$
		Preferences preferences = new ConfigurationScope()
		.getNode("org.eclipse.team.svn.ui.wizard.shareproject");
		Preferences preference = preferences.node("note1");
		this.isSimpleMode = preference.getBoolean(SELECTION_MODE, true);;
	}

and I have to change a few more lines to use isSimpleMode everywhere:

this.simpleModeRadionButton.setSelection(this.isSimpleMode);
....
this.advancedModeRadionButton.setSelection(!this.isSimpleMode); // Either or
this.advancedModeRadionButton.addSelectionListener(modeListener);

And I have to set the preference in the ModeListener

	protected class ModeListener extends SelectionAdapter {
		public void widgetSelected(SelectionEvent e) {
			//change controls area mode
			Button modeButton = (Button) e.widget;
			if (SelectProjectNamePage.this.simpleModeRadionButton == modeButton && SelectProjectNamePage.this.isSimpleMode == false) {
				SelectProjectNamePage.this.isSimpleMode = true;
				preference.putBoolean(SELECTION_MODE, true);
				enableControlsArea();
			} else if (SelectProjectNamePage.this.advancedModeRadionButton == modeButton && SelectProjectNamePage.this.isSimpleMode == true) {
				SelectProjectNamePage.this.isSimpleMode = false;
				preference.putBoolean(SELECTION_MODE, false);
				enableControlsArea();
			}
		}
	}

The full source code is attached.

SelectProjectNamePage

If you now export these two plug-ins into your runnig Eclipse, this dialog will remember the last selection (Simple vrs. Advanced).

As I hope this behavior is useful to others I created a bug report (with a patch). See Bug . I hope the subversion programmers will consider this patch (or an improved version of it).

Remember sharing is good. Open Source does not only allow you to solve your issues but it makes it easy to contribute back.

Here is what you can do to install subversion:

1. Install SVN Team Provider from

http://download.eclipse.org/technology/subversive/0.7/update-site/.

2. After installing SVN Team Provider and restarting Eclipse, I installed SVN
connectors from

http://www.polarion.org/projects/subversive/download/eclipse/2.0/update-site/.
