I do not know how  .... there might be some way ... but I have heard 
something similar to "is up to p2 to decide when it can or should clean up 
and get rid of things ... so it can atomically optimize things as it sees 
fit" ... but, not sure how much of that "optimizing function" has been 
implemented, since I too see growth but no cleanup. One of the reasons 
they are not deleted is that one design goal is to be able to revert to 
previous versions, so ... may not be easy to coordinate all that, while at 
the same time making sure the user knew that whey could no longer revert 
to ... so that may be why they lean towards leaving things around (though, 
in theory a revert could re-pull from a repository). 

Let us know if you find anything.

Subject:        [wtp-dev] Why plug-ins never get deleted?
Sent by:        [email protected]



Hi,

I installed several versions of some plug-ins. (uninstalling between 
installations) But at the end I get to have all versions of all plug-ins 
that I ever installed in the plugins directory of my eclipse. I also 
cleaned the "Installation History". Does anybody know how to get rid of 
the unused plug-ins?

Deleting does not work because when I try to install something else, it 
does not work any more, complaining that the missing plug-ins were 
missing.

Any clues?

Thanks!
Gabriel
