Hi
there should be a similar post in this newsgroup; to make bundlepool
work correctly, you need to specify a profile, that p2 will use to keep
track of the bundles (associated to specific profiles). Each
installation should have a different profile. You may also want to use
the option -shared to specify a directory where all profile information
will be stored.
Hope this helps

mh... probably I didn't get your question right the first time; it seems
you have an installed Eclipse and you want to use bundlepool for that
Eclipse? However, once an Eclipse has been installed without
bundlepools, you can't "turn" it to use bundle pool (as far as I
know)... you need to install a brand new Eclipse SDK from the command
line with the p2 director using bundlepool, something like
-installIU org.eclipse.sdk.ide
-tag InitialState -profile EclipseLunaSDK
from then on, that installation will be used shared bundlepools
automatically...
is this your scenario?
cheers

I guess that's one of the main reasons why bundlepool is not that popular ;)
By the way, you may want to try the new Oomph installer (that heavily
relies on bundlepool)

what I do for bootstrapping is downloading the standalone director
application (you can get it from
https://www.eclipse.org/buckminster/downloads.html )
I'm using some ant scripts to automate all my eclipse installations
(using bundle pooling); I still haven't got time to make it public, but
a blog post will hopefully come soon :)

I use a mnemonic name summarizing the main features installed in that
particular installation (e.g., LunaXtextLatest, MarsXtextStable, etc.)

I know, I filed a bug https://bugs.eclipse.org/bugs/show_bug.cgi?id=436222
that seems to be a regression since Luna.
