시작 예 (https://www.lwjgl.org/guide (변경되지 않은 상태))에서 LWJGL을 사용하려고하지만 OpenGL ES를 사용하도록 변경했습니다. 3.0 대신 (이 질문과 무관 한 이유로).현재 스레드에 OpenGL ES 컨텍스트 현재 없음 - OpenGL ES 3.0을 사용하는 LWJGL
필자는 최신 LWJGL Release 3.1.1을 사용하고 Minimal OpenGL ES를 사전 설정 (https://www.lwjgl.org/download)으로 선택하고 Windows 원어민을 사용하고 있습니다. (저는 Windows 10 64 비트를 실행 중입니다)
저는 고생하고 있습니다. 어떻게 고쳐야할지 모르겠습니다.
내가 오류가 있습니다 : 스레드 "주요"java.lang.IllegalStateException에서
예외 : 현재의 thread에 더는 OpenGL ES의 상황에 맞는 전류가 없습니다.
전체 오류 :
Exception in thread "main" java.lang.IllegalStateException: There is no OpenGL ES context current in the current thread.

그리고, 변경 : 내가 주석을 해제하는 경우가 ... 주목할 가치가 있는지 여부
