Multiple file submission in Java track

I was wondering whether the Java track supports submitting multiple files?

I was working on the Robot Simulator exercise on the track, made changes to both the Robot.java and Orientation.java and ran exercism submit src/main/java/Robot.java src/main/java/Orientation.java.

I can see an iteration with the changes in exercism, but the exercism shows compilation errors (gradle test runs just fine locally on my machine).

Which error are you getting on the online tests?

The error was:

I’m pretty sure I added those methods to Orientation in the iteration…
