Robocode Editor/Compiler troubles?
Oh, I thought this was some other option to add the robot to the repository/cache, but that's actually just the option for extracting the JAR to source files. So you have to extract every JAR for every robot to not get these errors?
I think you are confusing the Import downloaded robot tool with the Extract downloaded robot for editing tool.
Anyway, yeah, it seems I'll have to import each robot individually from now on.
