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?
