Linux 명령을 사용하고 Eclipse 바로 가기 없이 실행 가능한 .jar 파일을 만드는 방법은 무엇입니까?
게시 됨: 2022-01-03
지금까지는 Eclipse IDE에서 마우스 오른쪽 버튼을 클릭하고 몇 번의 간단한 클릭으로 실행 가능한 .jar 파일을 만드는 것이 너무 쉬웠습니다. 지난 주에 저는 일반적으로 많은 서비스를 호스팅하는 Digital Ocean 노드에서 실행 가능한 .jar file manually 생성해야 했습니다.
명령어만으로 .jar 파일을 직접 생성하는데 시간이 좀 걸리긴 했지만 10분 만에 실행 가능한 .jar 파일이 완성되었습니다.
아래 질문 중 하나가 있으면 올바른 위치에 있습니다.
- Linux 명령줄에서 jar 파일을 만드는 가장 좋은 방법
- Linux에서 jar 파일을 실행 가능하게 만드는 방법은 무엇입니까?
- Linux에서 jar 파일을 어떻게 컴파일합니까?
- JAR 파일을 Linux 실행 파일로 만드는 방법은 무엇입니까?
- Linux 터미널에서 .Jar 파일을 만들고 실행하는 방법은 무엇입니까?
시작하자:
1단계) Linux 시스템에 Java가 설치되어 있는지 확인
Java가 이미 설치된 경우 step-4 직접 이동합니다. javac 명령을 실행하고 아래 결과가 표시되면 호스트에 Java가 설치되지 않은 것입니다.

root @ localhost : ~ / java / src # javac Command 'javac' not found , but can be installed with : apt install openjdk - 11 - jdk - headless apt install default - jdk apt install openjdk - 8 - jdk - headless apt install ecj |
2단계) Linux 호스트에 Java 설치

3단계) Java에서 확인
아래 명령을 다시 실행하면 설치된 Java 세부 정보가 표시되어야 합니다.

모든 준비가 완료되었습니다.
위와 같이 /root/crunchify/src/build 폴더 아래에 Crunchify.jar 파일이 생성되었습니다.
