How do I retrieve Eclipse RCP Product Version from IProduct

I wish to programatically determine the version of my RCP Product.

I've found the Platform.getProduct() method, which returns an IProduct object. But, this does not have version details. I can navigate into the getDefiningBundle object, but that only has the version id of the plugin project, not the version number in the .product file.

Any tips most welcome.

Hi may be this code will help you to get the version of you product file

IProduct product = Platform.getProduct();

Version version = product.getDefiningBundle().getVersion();

Eventually figured out you can query the p2 product IUs to retrieve the versions of installed products. I'm doing this in a custom splash handler, and have a lot of null guards in as I'm not entirely sure how much of this API will be available in development environment launch configs. You might be comfortable removing those! I think you could probably construct a P2 query for the specific product IU instead of looping through all the products like I did. Pretty sure it's also possible to obtain the active profile without using ProvisioningUI, but that was good enough for me.

import org.eclipse.equinox.p2.core.IProvisioningAgent;
import org.eclipse.equinox.p2.engine.IProfile;
import org.eclipse.equinox.p2.engine.IProfileRegistry;
import org.eclipse.equinox.p2.metadata.IInstallableUnit;
import org.eclipse.equinox.p2.operations.ProvisioningSession;
import org.eclipse.equinox.p2.query.IQuery;
import org.eclipse.equinox.p2.query.IQueryResult;
import org.eclipse.equinox.p2.query.QueryUtil;
import org.eclipse.equinox.p2.ui.ProvisioningUI;

private org.eclipse.equinox.p2.metadata.Version getProductVersion() {
    ProvisioningUI provisioningUI = ProvisioningUI.getDefaultUI();
    if (provisioningUI == null) return null;

    String profileId = provisioningUI.getProfileId();
    ProvisioningSession session = provisioningUI.getSession();
    if (profileId == null || session == null) return null;

    IProvisioningAgent provisioningAgent = session.getProvisioningAgent();
    if (provisioningAgent == null) return null;

    IProfileRegistry registry = (IProfileRegistry) provisioningAgent.getService(IProfileRegistry.SERVICE_NAME);
    if (registry == null) return null;

    IProfile profile = registry.getProfile(profileId);
    if (profile == null) return null;

    IQuery<IInstallableUnit> iuProductQuery = QueryUtil.createIUProductQuery();
    IQueryResult<IInstallableUnit> result = profile.query(iuProductQuery, null);
    if (result == null) return null;

    for (IInstallableUnit productIU : result) {
        if (PRODUCT_ID.equals(productIU.getId())) {
            return productIU.getVersion();
        }
    }

    return null;
}

As @dystroy mentioned, the only product version that is available from the IProduct is the defining/branding bundle's version. If they match, then you're done.

These days, the product version is stored in the RCP application's p2 profile, in the product IU.

eclipse -noSplash \
-application org.eclipse.equinox.p2.director \
-metadataRepository \
file://$(pwd)/p2/org.eclipse.equinox.p2.engine/profileRegistry/SDKProfile.profile \
-list | grep ^org.eclipse.sdk.ide

returns org.eclipse.sdk.ide=4.2.2.M20121008-1100. But I'm not sure of the p2 wizardry necessary to extract IUs from the currently running instance's p2 profile.
