Sonarqube Webapp did not start

Question

I am installing SN5.5 using PostgreSQL9.5 under Windows. Unfortunately, I am hitting error "Webapp did not start".

Below is the full stack trace. I think I got the error first at line "Exception sending context initialized event to listener instance of class org.sonar.server.platform.PlatformServletContextListener"

org.sonar.api.utils.MessageException: Current version is too old. Please upgrade to Long Term Support version firstly.

This log means than you're trying to upgrade to a too recent version. You should first upgrade to the nearest LTS version (probably 4.5.X), then you'll be able to upgrade to 5.5.

See http://docs.sonarqube.org/display/SONAR/Upgrading for more information about the upgrade strategy.
