Hi,

I'm trying to update my application using P2 following this online tutorial.

I have a p2 repository hosted on a local Apache server and my application doesn't seems to detect updates on it. There is also no P2 request logged in the access.log of the Apache server.

So I have two problems :
- When my p2 repo does not exist, update service doesn't throw an error or a warning.
- When my p2 repo is up and contains update, the update service tells me that there is no available update.

Do you have any advice to debug it simply ? or help me with some example code?

Here the code of my update handler :

public class UpdateHandler {
	
	/** The Logger */
	private static final Logger LOG = Logger.getLogger(UpdateHandler.class);
	
	/** The Repository URL */
	private static final String REPOSITORY_LOC = "http://localhost/repository";
	
	@Inject
	UISynchronize sync;
	
	@Execute
	public void execute(IProvisioningAgent agent, UpdateService updateService, IWorkbench workbench) {
		LOG.debug("execute: " + this.getClass().getName());
		
		LOG.debug("Adding P2 repository : " + REPOSITORY_LOC);
		P2Util.addRepository(agent, REPOSITORY_LOC);
		final CancelableOperation<Optional<UpdatePlan>> check = updateService.checkUpdate(ProgressReporter.NULLPROGRESS_REPORTER);
		
		check.onCancel(() -> showInformation("Operation cancelled"));
		check.onException(t -> showError(t.getStatus().getMessage()));
		check.onComplete(updatePlan -> {
			
			if (!updatePlan.isPresent()) {
				showInformation("Nothing to update");
			}
			else {
				if (showConfirmation("Updates available", "There are updates available. Do you want to install them now?")) {
					
					final CancelableOperation<UpdateResult> result = updatePlan.get().runUpdate(ProgressReporter.NULLPROGRESS_REPORTER);
					
					result.onCancel(() -> showInformation("Operation cancelled"));
					result.onException(t -> showError(t.getLocalizedMessage()));
					result.onComplete(r -> {
						if (showConfirmation("Updates installed, restart?", "Updates have been installed successfully, do you want to restart?")) {
							sync.syncExec(() -> workbench.restart());
						}
					});
				}
			}
		});
	}
}

And my P2Util used to add the repository location :

public class P2Util {
	
	/** The Logger */
	private static final Logger LOG = Logger.getLogger(P2Util.class);
	
	public static boolean addRepository(IProvisioningAgent agent, String repo) {
		
		IMetadataRepositoryManager metadataManager = (IMetadataRepositoryManager) agent.getService(IMetadataRepositoryManager.SERVICE_NAME);
		IArtifactRepositoryManager artifactManager = (IArtifactRepositoryManager) agent.getService(IArtifactRepositoryManager.SERVICE_NAME);
		
		if (metadataManager == null) {
			LOG.error("metadataManager is null!!!");
			return false;
		}
		if (artifactManager == null) {
			LOG.error("artifactManager is null!!!");
			return false;
		}
		try {
			URI uri = new URI(repo);
			metadataManager.addRepository(uri);
			artifactManager.addRepository(uri);
			
			return true;
		} catch (Exception e) {
			return false;
		}
	}
}
