[p2-dev] FW: [emf-dev] Possible bug in EMF all-in-one distribution
|
See attached re. my recent problems with the EMF update site
distribution. I can't really say either way, but sounds like there needs
to be an agreement between you guys! Can one of you get in touch with
them and resolve this issue so other users don't have the same problem
as me?
Cheers guys, and thanks again for getting me a working solution.
Tom

IMHO the fact that p2 doesn't check locally for a .jar.pack.gz before
going to the web is still a bug in p2. A local repo, whether a zip or a
folder, ought to have the same 'see if there's a packed jar just in
case' behaviour - isn't that like one line of
if-jar-exists-then-install,elseif-jar.pack.gz-exists-then-install-else-c
heck-the-web
code?
And since the zip is installable as a zip, which is easier/faster than
unpacking it first, and can be installed via director using the jar:
prefix, I consider this a WORKSFORME.
If you disagree, open a bug and I'll point you at the code that does the
jar packing, metadata gen, and zip packaging. Patches welcome.
