Hello,

I am trying to get the headless p2 update example to run on a local
repository. I have pulled the code from the MailRCP example found here.

http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.equinox /p2/examples/org.eclipse.equinox.p2.examples.rcp.prestartupd ate/?root=RT_Project

I have modified P2Util to change the URI repository locations that are
searched. I have replaced:

final URI[] reposToSearch =
manager.getKnownRepositories(IRepositoryManager.REPOSITORIES _ALL);

with

URI[] tempReposToSearch = null;
try {
tempReposToSearch = new URI[] {(new
URI("file:///C:/Documents%20and%20Settings/Mike/Desktop/test/"))};
} catch (Exception e) {
System.err.println("Exception");
}

final URI[] reposToSearch = tempReposToSearch;

when the update runs with the above modification on my repo the line

IStatus status = engine.perform(profile,
new DefaultPhaseSet(), plan.getOperands(),
pc, sub.newChild(100, SubMonitor.SUPPRESS_ALL_LABELS));

returns an Error status with a message of "An error occurred while
collecting items to be installed", an error code of "4" and no exception.

I have even tried

final URI[] reposToSearch = new URI[] {(new File("C:\\Documents and
Settings\\Mike\\Desktop\\test\\").toURI())};

with no luck. Can someone please help.

Thanks,
Mike

Ok I think i figured this one out. It looks like if you pass a progress
monitor to the plan executor it fails in the described fashion but if
you set the monitor to null it works just fine.

Dosen't Work:
IStatus status = engine.perform(profile, new DefaultPhaseSet(),
plan.getOperands(), pc, sub.newChild(100, SubMonitor.SUPPRESS_ALL_LABELS));

Works:
IStatus status = engine.perform(profile, new DefaultPhaseSet(),
plan.getOperands(), pc, null);

No to figure out why it is causing the problem.
