[ivy] 내부 파일 캐시(xml, xml.original, properties)

ivy 기반 빌드 프로젝트는 ~/.ivy 디렉토리를 사용한다. 

예를 들어, play1 framework는 ~/.ivy/cache 디렉토리에 저장된 의존 lib가 저장된다. 

예를 들어, org.apache.httpcomponents.httpcore는 아래와 같이 저장된다.

~/.ivy2/cache/org.apache.httpcomponents/httpcore

$ ls

ivy-4.2.4.xml            ivy-4.3.3.xml.original   ivy-4.4.4.xml            ivydata-4.3.3.properties jars

ivy-4.2.4.xml.original   ivy-4.4.1.xml            ivy-4.4.4.xml.original   ivydata-4.4.1.properties sources

ivy-4.3.3.xml            ivy-4.4.1.xml.original   ivydata-4.2.4.properties ivydata-4.4.4.properties

디렉토리에는 버전 별 xml 파일, xml.original 파일, jars, sources가 있다.

xml.original 파일은 pom 다음과 같다. 

$ cat ivy-4.4.4.xml.original

<?xml version="1.0" encoding="UTF-8"?>

만약 ivy 컴파일일 실패하면, jars에 jar가 있는지. properties,xml, xml.original 파일이 존재하는지 확인해본다.

참고

ivy 파일 이슈를 해결해도

컴파일 안되면, maven repository 이슈이다.
