Can anyone offer an explanation for the p2 installation message:
"Failed to prepare partial IU: [R]my.plugin.id 1.2.0"
This occurred while testing installation from an update site that was
build using Tycho. The dialog message says:
"'Install' has encountered a problem.
An error occurred during provisioning."
With the message above in the Details >> section.
Any hints about what this means?
TIA,
Eric

We're using the latest Tycho and Eclipse 3.4, so I think they should be
compatible.
Our buildmaster guy had removed the Tycho-generated p2 data from the
site because we've had troubles before with those files that are built
from the IDE. When he left them in, we get the dreaded "unable to find a
solution..." error from p2. Unfortunately, those error messages are next
to useless for debugging what is wrong with a site, so...

In our case, the "failed to prepare partial IU" error happened when
artifacts.xml had been removed from the update site.
