개미를 사용하여 원격 서버의 기존 프로젝트를 백업하는 방법

Question

아래의 ant 빌드 스크립트를 사용하여 내 응용 프로그램을 배포하고 있습니다. 내 응용 프로그램은 내 개미 스크립트에 언급 된 지정된 서버에 배포됩니다. 하지만 난 새로운 프로젝트를 배포하기 전에 원격 서버에 기존의 배포 된 프로젝트를 취소하고 싶습니다. 여기 개미 대본이 있습니다.

URL 매개 변수는 다음과 같습니다 :

update: When set to true, any existing update will be undeployed first.... 
tag: Specifying a tag name, this allows associating the deployed webapp 
     with a tag or label. If the web application is undeployed, it can be 
     later redeployed when needed using only the tag. 

불행하게도, ANT 작업 문서는 설명하지 않습니다

Answer 1

은 관리자 설명서는 응용 프로그램을 다시 배포하는 데 사용할 수있는 special tag attribute 설명 이 속성에 대한 지원 ...

흥미롭게도 Maven plugin이 이것을 지원하지만 빌드 도구를 전환하면이 문제에 대한 극단적 인 해결책이 될 것입니다 :-)
