Hi everyone, I've seen old unresolved topics about this from 2015.
The build fails at the very end and throws on 64 compiling script errors from Vuforia scripts as on image.
It is a very simple example project working on the Webcam Play Mode.
I have the latest version of Unity 2017.2.0f3, latest Vuforia Update,
jdk 9.0.1, and an older working tools folder version of sdk (25.2.5, because the latest isn't recognized).
