Line 197:

Code:

public HashMap<Player, String> kitselected = new HashMap<Player, String>();
public void giveSelectedKit(final Player p) {
String kit = kitselected.get(p);
LINE 197: if (kit.equalsIgnoreCase("defender")) {

Line 76:

Code:

public MainMenu menu = new MainMenu(plugin);
LINE 76: menu.giveSelectedKit(p);

THIS LINE IS ONLY HAS AN ERROR BECAUSE THE NULL IS ON LINE 197

 

You didn't check if the hashmap contained p, if it doesn't it returns null. Don't use Players if you plan on keeping it long term.
