Java 8의 Spring Boot 응용 프로그램에서 gradle wrapper가 실패합니다. Gradle 3 : cacerts를 찾을 수 없습니다.

Question

gradle wrapper 명령을 사용하여 gradlew 파일을 만들 때 문제가 발생했습니다. 내 설정은 간단하다 : 우분투 14.04 + 자바 8 (오픈 JDK 버전 "1.8.0_91") + Gradle을 3.0

자습서를 사용 :

• https://spring.io/guides/gs/spring-boot/#scratch
• https://docs.gradle.org/current/userguide/gradle_wrapper.html

의 호기심 일 이 문제는 gradle wrapper이 실패하는 이유는 파일 또는 디렉토리가 분명히 누락 되었기 때문입니다.하지만 그렇지 않습니다 (아래 'check cacerts file/directory'참조). 비록 이것이 문제가된다면 알려 주시기 바랍니다. 링크이며 실제 파일/디렉토리는 아닙니다. 누락 된 cacerts 오류가 캐스케이드 오류의 끝 부분에있는 것 같으면 다른 문제가 있는지 모르겠지만이를 디버그하는 데 도움이 될 것입니다.

관련 파일과 출력물은 다음과 같습니다.

당신은 아마 here 및 here을보고 댕글 링 인증서 표시에 심볼릭 링크를 왼쪽 버그를 치고있다. 해결 방법 중 하나는 ca-certificates-java 패키지를 다시 설치하는 것입니다. 이렇게 :

$ sudo dpkg --purge --force-depends ca-certificates-java 
$ sudo apt-get install ca-certificates-java
