A great many add-ons, like the NVDA core code itself, are managed via GitHub.  And that's whether they're officially vetted add-ons or not.

There are three add-ons for Eclipse, two of which have been updated this year.  See:  https://github.com/search?q=Eclipse+NVDA&type=

Simply going to GitHub and entering NVDA plus one other word specific to the add-on in question generally zeros in on what's being looked for.
