How can I rerun my UpgradeProcess?

I dont have any specific version in my bnd file, only the Bundle-Name and the Bundle-SymbolicName. The bundle version is automatically inserted to the metadata of the module by the maven bnd plugin. So there is no need to put it there.

Hey Matt,

I'm not convinced that it totally correct. The reason I say that is because when 7.0 was first released service builder changes were not automatically applied. The "correct" approach was to change the version numbers and include upgrade steps. I know that now, with the portal-developer properties included, that is no longer needed (locally) but for deployments outside of local, an upgrade task I believe is still best practice. What version do you have in you bnd file for your module?

Hey Andrew, thanks for your answer, but I guess that this won't work anymore. I found this line in the Liferay code.

if (PropsValues.UPGRADE_DATABASE_AUTO_RUN ||
    (_releaseLocalService.fetchRelease(bundleSymbolicName) ==
        null)) {
    _upgradeExecutor.execute(
        bundleSymbolicName, upgradeInfos,
        OutputStreamContainerConstants.FACTORY_NAME_DUMMY);
}

So the UpgradeProcess will only rerun, if that portal property is set or if the bundleSymbolicName is not present in the release table. So changing versions won't have any effect. I have to rename my complete bundle if I want to execute my UpgradeProcess once again. This is actually a huge drawback compared to Liferay 6, but apparently you cannot change anything about that.

Hey Matt,

Never tried this oen myself but I have made a mistake in the past (easy to overlook) where I wrote the upgrade task but then forgot to change the version information in the bnd file. Did you remember to make that change as well?

You probably did but I thought I would ask anyway -- even if you didn't, someone else that comes along might have :)

Hello guys,

I am kind of used to the old Liferay 6.2 UpgradeProcess, but now I have to write my first UpgradeProcess for Liferay 7.3 and I don't know how to execute it for a second time. Here is my code:

@Component(immediate = true, service = UpgradeStepRegistrator.class)
public class MyUpgradeRegistrator implements UpgradeStepRegistrator {

	@Override
	public void register(Registry registry) {
		registry.register("0.0.0", "1.0.0", new com.sample.upgrade.v1_0_0.MyUpgradeStep());
	}

}

After deploying that component, the code in MyUpgradeStep is executed correctly. And if I redeploy the jar file, nothing happens, which is also correct. Now I change the code to:

@Component(immediate = true, service = UpgradeStepRegistrator.class)
public class MyUpgradeRegistrator implements UpgradeStepRegistrator {

	@Override
	public void register(Registry registry) {
                registry.register("0.0.0", "1.0.0", new com.sample.upgrade.v1_0_0.MyUpgradeStep());
                registry.register("1.0.0", "2.0.0", new com.sample.upgrade.v2_0_0.MyUpgradeStep());
	}

}

My expectation is that the first UpgradeStep does not run because it was already executed, but the second should run because it was never executed before. However, nothing happens. What did I wrong?
