Question

There is an article in the Eclipse wiki how to configure user's p2 default repositories of an RCP application by adding a static conf file to your product:

Equinox/p2/Adding Self-Update to an RCP Application - Configuring the user's default repositories

I want to do the same programmatically in a Java class when the user changes some configuration details. I could not find appropriate p2 API documentation for that.

Was it helpful?

Solution 2

I found a solution. It's easy - unfortunately there is no documentation...

    // from bundle org.eclipse.equinox.p2.console
    import org.eclipse.equinox.internal.p2.console.ProvisioningHelper;

    URI repoUri = new URI(UPDATE_SITE_URL);
    try {
        ProvisioningHelper.addMetadataRepository(repoUri);         
    } catch( Exception e ) {
        LOG.warn("Can not add update repository: " + repoUri);           
    }
    try {
        ProvisioningHelper.addArtifactRepository(repoUri);          
    } catch( Exception e ) {
        LOG.warn("Can not add update repository: " + repoUri);
    }

OTHER TIPS

Use this solution for Eclipse 3.7 based applications:

final ProvisioningUI ui = ProvUIActivator.getDefault().getProvisioningUI();
IArtifactRepositoryManager artifactManager = ProvUI.getArtifactRepositoryManager(ui.getSession());
artifactManager.addRepository(new URI(UPDATE_SITE_URL);

IMetadataRepositoryManager metadataManager = ProvUI.getMetadataRepositoryManager(ui.getSession());
metadataManager.addRepository(new URI(UPDATE_SITE_URL);

For ProvUI and ProvisioningUI you have to import bundles org.eclipse.equinox.p2.ui and org.eclipse.equinox.p2.operations (among others).

Furthermore you can add more than one repositories with ElementUtils and also you can sort them.

MetadataRepositoryElement[] element = new MetadataRepositoryElement[links.length];
    for (int i = 0; i < links.length; i++) {
        element[i] = new MetadataRepositoryElement(null, new URI(links[i]), true);
        element[i].setNickname("Link-"+i);
    }
    ElementUtils.updateRepositoryUsingElements(element, null);

These links will be appeared alphabetically sorted.

This is high on the Google query for this issue, and there's still not a good way to do it published:

If anyone finds this page via Google as I did, I've solved this problem. You can use org.eclipse.equinox.internal.p2.ui.model.ElementUtils.updateRepositoryUsingElements to set the repositories programmatically. Full code can be found here.
