If you use something like

import edu.wpi.first.wpilibj.Jaguar;

public class FullSpeedAhead{
    Jaguar motor;
    public FullSpeedAhead(){
        motor = new Jaguar(1);
    }
    public void go(){
        motor.set(1);
    }
}

then your code should work just fine regardless of your IDE, assuming you have your files in the right place (edu.wpi.first.wpilibj.TeamXXYY seems to be standard). Jaguar.set() is no better/worse than the methods it actually uses to set the given value to the Jaguar, but using it is simpler than other methods.
