Javac에서 기호를 찾을 수 없음 - 오류 가져 오기?

Question

나는 컴파일하려고하는데, 나는 100 % 긍정적이다. 나는 모든 것을 정확하게 가져왔다. 내 오류 : 사람이 내가 잘못 뭘하는지 말해 줄 수 있다면

... 그리고 내 된 .java 파일입니다! .class 파일을 jd-gui.exe로 디 컴파일 한 다음 .txt 문서에 코드를 복사하고 편집 한 다음 .java 파일로 저장했습니다. 지금 컴파일 할 수 없습니다 ...

Answer 1

오류는 컴파일러가 클래스 net.minecraft.launcher.Launcher을 찾지 못했다는 의미입니다. 즉, 소스 경로에 Launcher.java 소스 파일을, 클래스 경로에 Launcher.class를 찾을 수 없습니다.

아마도이 클래스를 생성/변경하지 않았다는 가정하에 Launcher.class가 포함 된 JAR 파일을 클래스 경로 (옵션 -classpath 또는 환경 변수 CLASSPATH)에 추가해야합니다. 그렇지 않으면 소스 경로 (옵션 -sourcepath)를 조정해야합니다 (javac 참조).

import은 코드에 net.minecraft.launcher.Launcher 대신 Launcher을 입력 할 수 있습니다.
