Can't use normalRelativeAngleDegrees(*)

[OneAndrew]

Hi

I am trying to create a robot like Tracker but the compiler doesn't let me use "normalRelativeAngleDegrees(*). It gives the following

error. How do I obtain source level 1.5 or greater?

Syntax error, static imports are only available if source level is 1.5 or greater

import static robocode.util.Utils.normalRelativeAngleDegrees;

regrards,

andrew
