다중 릴리스 jar를 작성하는 중 오류 "항목 : A.class, 내부 이름이 com.vipin.exp.A이고 이름이 일치하지 않습니다"

Question

여기서 java9/com/vipin/exp/A.class는 파일 I입니다. jdk 9와 다른 버전의 java8/com/vipin/exp/A.class에 사용하고 싶습니다. 이를 위해 다중 릴리스 항아리를 만들려고하지만 오류가 발생하는 중입니다. 이 명령에서 무엇이 잘못 되었습니까?

XXXX@XXX-MacBook-Air.local:~/javacode$ pwd 
    /Users/XXXX/javacode 
XXXX@XXX-Air:~/javacode$ javac --release 9 -d /Users/nitinkumarsharma/javacode/java9/ java9/com/vipin/exp/A.java 
XXXX@XXX-Air:~/javacode$ javac --release 8 -d /Users/nitinkumarsharma/javacode/java8/ java8/com/vipin/exp/A.java 
XXXX@XXX-Air:~/javacode$ jar -c -f vipin.jar -C java8/com/vipin/exp/ . --release 9 -C java9/com/vipin/exp/ . 

     entry: A.class, contains a class with internal name com.vipin.exp.A, names do not match 
     entry: META-INF/versions/9/A.class, contains a new public class not found in base entries 
     Warning: entry META-INF/versions/9/A.java, multiple resources with same name 
     invalid multi-release jar file vipin.jar deleted 

내 디렉토리 구조는 다음과 같습니다 나는

XXXX@XXX-MacBook-Air.local:~/javacode$ jar -c -f vipin.jar -C java8/com/vipin/exp/ . 
XXXX@XXX-MacBook-Air.local:~/javacode$ ls -ltr

Answer 1

아래 -C 옵션의 나의 이해는 잘못처럼, 항아리를 만드는 하나 개의 클래스 파일을 사용할 때

XXXX@XXX-MacBook-Air.local:~/javacode$ tree 
. 
|____java8 
| |____com 
| | |____vipin 
| | | |____exp 
| | | | |____A.class 
| | | | |____A.java 
|____java9 
| |____com 
| | |____vipin 
| | | |____exp 
| | | | |____A.class 
| | | | |____A.java 

그것은 잘 작동 , -C 후에 최상위 디렉토리를 제공해야합니다.

XXXX@XXX-MacBook-Air.local:~/javacode$ jar -c -f vipin.jar -C java8 . --release 9 -C java9 .

이 명령은 올바른 아래 것 질문 위의 생산 잘못된 출력에 주어진 일했다 당신은 클래스 파일이 올바른 구조에서 사용할 수 TVF 출력에서 ​​볼 수있는 COM/비핀/특급/A.class

XXXX@XXX-MacBook-Air.local:~/javacode$ jar -c -f vipin_test.jar -C java8 .

더 많은 명령이 완벽하게 작동했습니다.
