You can change the JDK from "JDK 1.7 (latest)" to one of the JDK 9 versions. Since there's no official release of 9 yet, they don't seem to have a "JDK 9 (latest)" profile set up on Jenkins yet.
As for building this, the best solution I've seen so far basically involves a bit of manual configuration using some inline ant tasks or similar overly complicated nonsense which doesn't work well in any IDE to date. It may be worth investigating the existing maven plugin ecosystem and seeing if we need a custom plugin developed for this. Could be a useful feature addition to maven-compiler-plugin, though I haven't tried contributing to Maven yet. Using Maven profiles would help with this so that we can still build most of the project locally with JDK 1.7 or 1.8 as I doubt everyone wants to install JDK 9 on all their development machines while it's still in beta.
