| Download all components during resolution phase? [message #929744] |

Hi,
Is it expected that the resolution phase (that what happens before the import dialog pops up) takes hours because it
effectively downloads each and every bundle? I thought the resolution phase infos can be gathered from the global
repository files (content.xml, artifacts.xml)...
I can currently not check whether they're downloaded *again* after the dialog in the install phase because I have
resolution errors. But it takes ages to diagnose them because the resolution takes so long.
Is it possible that I'm doing something wrong? Strange that this morning I had the feeling everything was okay. Maybe I
don't realize all the downloads in the resolution phase when the network is faster.
Cheers
/Eike

I fetch my sources from Git and all their dependencies from ~12 p2 repositories. The majority of the total components
(BOM) comes from p2 repositories and I saw that those are eagerly downloaded at resolution time.

Okay, okay, that was a minor exaggeration :P
But it took ~1h instead of the usual 5 minutes.

Too late. I just remember that on Monday it took magnitudes longer than on Sunday (and usually). And that the time was
being spent in the resolution phase.

No. Well, it did complete but with resolution errors. That's why I complained. The diagnostic output is sometimes not
very good so it's kind of a ping pong game between me and my releng files. The resolution phases taking an hour each is
even more annoying then.

Yeah, I know that from the past. I used to turn mirrors off via eclipse.ini but that slows down enormously in Europe
(given that the mirrors are okay). So I switched it on again and in the last 1 or 2 years I didn't experience much trouble.
Even with bogus mirrors in mind I can not see why components like org.eclipse.core.runtime_xxx.jar need to be fully
downloaded at resolution time.

They are not downloaded at resolution time unless you explicitly ask Bucky to do so by using "url" providers in your
RMAP as opposed to a "p2" or "maven" or have some other special code that downloads jars directly from SVN/CVS or the like.
