Such abrupt failure of the build usually happens when Rush fails to invoke the Java compiler (javac). There could be many reasons behind this, but the two I can currently think of are:
- You don’t have JDK (Java Development Kit) installed, or
javacis not on the system path variable; quite unusual, but may happen.
Can both of you try running javac in the terminal? If you get an error saying command/program not found, you might need to install JDK 8, or add javac to your system’s path variable.
PS: @72erdelyi, you seem to have JDK installed on your computer. It might be that javac is not your system’s path var.
