I get an error when trying to compile your project:

The warnings seem to be customary (cf. google/guice#1133 ), but I'm not sure I can debug the errors. I can give more detailed log if needed.

Does updating my java seems the right way to proceed? It is fairly version, but the _open_jdk version, maybe I need Oracle's JDK? I know there are ways to do it ( https://www.digitalocean.com/community/tutorials/how-to-install-java-with-apt-on-debian-9#installing-the-oracle-jdk ).

(I should update the title…).

I can compile:

What am I missing?

My most recent commit will fix that. The java version target was set lower, it should be good now.
