javadoc "error: package android.os does not exist" 에러가 날때

프로그래밍/java 2022. 1. 26. 22:58
반응형

javadoc 실행시 참조하는 패키지를 찾지 못할때 발생하는 에러로 javadoc 버전에 영향을 받음

최신 버전으로 사용할 경우 에러 발생함

 

/usr/lib/jvm/java-16-openjdk-amd64/bin/javadoc   => 에러 발생

error: package android.os does not exist
import android.os.RemoteException;

......

25 errors

 

패키지 경로를 추가하는 등의 방법으로 해결가능해 보이지만 수정에 한계가 있어 보임

꼭 javadoc 버전을 정해서 사용해야 되는 것이 아니라면 낮은 버전의 javadoc 사용으로 해결됨

/usr/lib/jvm/java-8-openjdk-amd64/bin/javadoc => 에러없이 문서가 만들어짐

                                                                                      갯수는 동일 하나 에러가 아닌 warning으로 처리됨

Swing CustomLineBorder 만들기(top, left, bottom, right 지정하여 적용하기)

나중에 같은 동작을 하는 MatteBorder 가 있다는 거 확인함.... 만들기 전에 찾아봐야돼~
