The same happens for all the other samples, so I guess I'm missing a jar, but maven doesn't really show any errors downloading.

[guille.r...@gmail.com]

Looks like you are missing the pythagoras jar (https://github.com/samskivert/pythagoras)

It is referenced in playn/core/pom.xml. No idea why it is not being found, though.

Apparently the jar was somehow corrupted?

Fixed it by deleting .m2/repository and:

mvn clean test -Pjava
