해결 방법

Jenkins 공식 홈페이지에서 가장 최근의 LTS 버전을 다운로드하였는데 너무 최신버전이라 적용이 안되는듯하여 아래 링크에서 전체 버전을 확인한 후 적당히 과거 버전으로 다운그레이드하여 다시 설치해주었다.

• Jenkins War Packages : https://get.jenkins.io/war-stable/

War Jenkins Packages

 

이 중에서 내가 선택한 버전은 2.319.2이다.

• Jenkins 2.319.2 : https://get.jenkins.io/war-stable/2.319.2/

Index of /war-stable/2.319.2

 

다시 배포 시도 ..

배포 성공!

deploy the application for the application [jenkins_2.319.2] succeeded
