Sometimes when I start a new topic in the eclipse ecosystem (especially around EMF) I have a difficult time figuring out how mature/widely used/coherent specific eclipse projects are (and how long these will stay around). Sometimes projects seem to vanish completely, sometimes they are moved but it is not documented properly, and sometimes they are basically unmaintained.
Is there a comprehensive overview/resource about the real life status of eclipse projects?
You can find all data relevant for the maturity of an Eclipse project via projects.eclipse.org on the metadata project page (for example, here about EGit):
Don't forget that also your involvement counts. Using open source without getting involved increases the risk that the project will be archived and there will be no more updates for you.
