You should be able to use Liquibase just fine on JDK 8 no matter how it's built. We just need to make sure it's compiled with JDK 7 so it can be used by people on that version still. It's actually currently actually built with JDK 6 but I'd be OK with increasing to 7 at this point. Java 7 is not supported in general even, but there are still a good number of people still using it. The main problem for us is not being able to use nice JDK 8 syntax that we'd like, but better to keep it available to more people.
I'll take a look at the Sonar setup, thanks.
Don't need anything else on the integrate side right now. I'm sure I'll have more questions once I look at it.
