Choosing plugins to update programmatically [message #1772891]

I would like to update a P2 repository with Eclipse 4 programmatically and I would like to choose plugins to update. Classic way to retrieve the provisioning job which updates the repository is:

ProvisioningSession session = new ProvisioningSession(agent);
UpdateOperation operation = new UpdateOperation(session);
operation.getProvisioningContext().setArtifactRepositories(new URI[] { uri});
operation.getProvisioningContext().setMetadataRepositories(new URI[] { uri});
IStatus status = operation.resolveModal(sub.newChild(100))
ProvisioningJob provisioningJob = operation.getProvisioningJob(monitor);
IStatus st = provisioningJob.runModal(monitor);

The resolveModal method checks plugins to update. If I print the possible updates I will have only the product and not the plugins to update.

Update[] updates = operation.getPossibleUpdates();

Now, how to choose the plugins I would like to updates? The UpdateOperation object constructor allows me to specify a list of Installable Units, but if I exclude only the plugin I do not want, the system equally updates all the repository.

IProfile self = profileRegistry.getProfile(IProfileRegistry.SELF);
IQuery<IInstallableUnit> query = new UserVisibleRootQuery();
IQueryResult<IInstallableUnit> roots = self.query(query, null);
Set<IInstallableUnit> iiu = roots.toUnmodifiableSet();
if (iiu != null) {
	for (IInstallableUnit i : iiu) {
				logger.info("NAME: " + i.getId() + " - VERSION: " + i.getVersion().toString());
	}
}

What I have from this code, that should search for available updates in all the repository is the only product, with version with timestamp changed (everytime I build with Tycho I have a new version 1.0.0.<timestamp>).

The application performs a simple check of the available updates. I do not need UI to do that.

What am I wrong ?

Thank you.

Hi again,

moreover I tried this piece of code (just trying if with this piece of code P2 is able to understand to update just this feature and not everything):

ProvisioningSession session = new ProvisioningSession(agent);
IProfile profile = profileRegistry.getProfile(IProfileRegistry.SELF);
query = QueryUtil.createLatestQuery(QueryUtil.createIUQuery("Feature_VersionGreen.feature.group"));
final IQueryResult<IInstallableUnit> result = profile.query(query, new NullProgressMonitor());
UpdateOperation operation = new UpdateOperation(session, result.toSet());
IStatus status = operation.resolveModal(monitor);

And I have this error message:

I do not know if this can help... Probably I am missing something.

Thank you for your precious help.
