Where is the "externalize strings" eclipse plug-in source code?

I need to look at "externalize strings" eclipse plug-in source code.

I have to make a modified version of that functionality and don't want to start from scratch. I try to import the plug-in using File->Import->Plug-ins and Fragments, which I think is the right way to do it, but I don't have a clue of what is the name of the plug-in, and it has not an intuitive name开发者_如何转开发 (or at least I have not found it) :-/

Any ideas of what is the name of the plug-in or where else can I find the source code of that specific functionality?

Thanks in advance

Simply use the plug-in spy (Alt+Shift+F1) on the Externalize String Wizard.

You will see that its class is the org.eclipse.jdt.internal.ui.refactoring.nls.**ExternalizeWizardPage**, invoked by the **ExternalizeWizard** class.

If you have the classic RCP eclipse edition, the sources are included: just click on the links displayed by the plug-in Spy.
(Otherwise, all sources are available at kickjava.com, as illustrated by the two previous links on the ExternalizeWizard[...] classes)
