Bukkit NullPointerException onEnable()

Question

새로운 플러그인을 작업하고 있는데,로드 할 때 "NullPointerException"오류가 발생하고 오류를 찾을 수있는 곳을 찾지 못하는 것 같습니다. 예외는 당신의 EntityManager.java 파일의 라인 296 던져

Answer 1

내가 해냈어!

RemoveEntities 변수를 설정하는 대신 RemoveEntities 클래스에 EntityManager 클래스의 변수를 찾도록 지시했습니다.

Answer 2

me.AngryCupcake274.EntityManager.EntityManager.loadConfiguration(EntityManager.java:296)

다음은 오류입니다. 시간 reme의이 시점에서

reme.arrow = getConfig().getBoolean("arrow"); 

은 여전히 ​​null이므로 당신은 arrow를 할당 할 수 없습니다. onEnable() 메소드에서 loadConfiguration()으로 전화하면 RemoveEntitites이 이미 인스턴스화되어 있는지 확인해야합니다.
