I downloaded Eclipse and am trying to create a launcher for it in the main menu. I finally figured out that a .desktop file needed to be made in /usr/share/applications, but I can't get the icon to show up. For the "Icon" field in the .desktop file, I tried giving an absolute path to an icon in my home folder, and I also tried putting the icon in all the folders under /usr/share/icons and just putting "eclipse" (the icon file name) as the value. I had copied this last from some of the existing .desktop files that worked, but still had no luck. Does anyone know how to do this?
