I have a package that I haven't used in awhile, and I just looked at it for the first time in a long time. I noticed that it depends on the motionplanningcommon stack. I am using ROS electric, and looking at the website it appears this stack is deprecated in electric. We are now supposed to use the arm_navigation stack.

Unfortunately, it seems that the arm_navigation stack doesn't have a definition for the PolygonalMap message. What is the recommended course of action for fixing this? Am I totally missing something?
