Maven 종속성 정리

프로젝트를 바쁘게 하나 둘씩 정리하고, 조금 여유를 가질 수 있게 되어서 레거시 프로젝트를 들여다 보고 있었습니다. WAS 로그를 찬찬히 살펴보던 중에, 특이한 warnning 로그가 찍혀있던 걸 확인하고 이에 대해 트러블 슈팅 했던 경험을 공유해봅니다.

Maven 과 Maven Tree

프로젝트 소스 관리 툴(예: Apache Maven 등)을 사용하다 보면 의도치 않은 dependency 문제를 자주 마주하게 됩니다. 예를 들어 조직 내부에서만 사용하는 동료가 만든 라이브러리를 참조하거나, 외부 라이브러리의 사용 등에서 충돌이 일어나거나 (대부분 로깅이나 헬퍼 및 유틸 모듈 등이 쉽게 충돌합니다.) 혹은 starter kit 형태의 프레임워크를 사용했을 때, 또는 특정 자리에서는 빌드되던 것이 다른 환경에서는 빌드가 안 되는 경우에 대부분 인지하지 못한 의존성 문제로 일어나곤 합니다.

이런 경우를 대비해서 대부분의 프로젝트 관리 툴에서는 ‘종속성 충돌 회피’ 개념을 가지고 있으며, 개발자는 이 기능을 통해 직접 종속성을 컨트롤 할 수 있습니다.

서론에서 말했던 저의 상황은 아래와 같습니다.

(아래는 문제의 WAS 로그)

로그를 살펴 보면 서블릿 관련 종속성에서 버전이 3.x 와 2.x 가 간의 충돌이 일어났으며, 서블릿 2.x 대 버전을 로드 하지 않았다는 의미의 로그가 있습니다. (log4j 관련해서도 충돌이 있다는 경고도 껴있네요.)

이놈들이 어디서 굴러왔는지는 커밋 로그를 뒤져보면 알겠지만, 구린 냄새가 풀풀 나는 걸 방치해둘 수는 없기에 충돌을 풀어줘야 합니다.

Maven Tree

종속성의 충돌을 찾는 방법 중에서 가장 심플한 접근 방법은 직접 Maven 의 종속성 트리를 찍어 보는 것입니다. 터미널에서 아래 종속성 트리 커맨드를 입력 하면 트리 구조로 쉽게 파악할 수 있습니다.

mvn dependency:tree

터미널에서 위의 maven 커맨드를 실행시키면, 아래처럼 이쁘게 종속성 트리가 출력 됩니다.

찾아보니 범인은 phoenix jdbc (org.apache.phoenix:phoenix-queryserver-client) 요녀석으로.. 안에서 참조되는 dependency 에서 충돌이 일어나고 있었습니다.

이러한 충돌이 있었는 데도 지금껏 별 무리 없이 어플리케이션이 구동되어왔던 것은 Maven 은 동일한 이름의 아티팩트(라이브러리)가 있을 경우 기본적으로 어플리케이션에서 직접 선언 한 dependency 를 최우선적으로 로드합니다. 이를 다시 설명 하면 메이븐 트리에서 어플리케이션을 최상단 ROOT 로 기준으로 했을 시 동일한 아티팩트가 있을 경우에 가장 가까운 라이브러리를 로드하기 때문입니다.

javax.servlet:servlet-api를 예롤 설명하면, phonix driver 안에서 2.x 대의 servlet-api 를 사용하고 있었지만, 최상단인 어플리케이션에서 3.x 대의 servlet-api 를 직접 선언하였음으로, 2.x 누락 되고 3.x 가 로드되어진 것을 알 수 있습니다.

Maven Dependency Exclusion

Maven 에서는 의존성 목록 중에서 제외 할 특정 아티팩트를 정의 할 수 있습니다.

아래처럼 종속성을 제외 처리 하는 exclusions 엘리먼트를 선언합니다.

<dependency>
    <groupId>org.apache.phoenix</groupId>
    <artifactId>phoenix-queryserver-client</artifactId>
    <version>4.14.0-HBase-1.1</version>
    <exclusions>
        <exclusion>
            <groupId>javax.servlet</groupId>
            <artifactId>servlet-api</artifactId>
        </exclusion>
        <exclusion>
            <groupId>javax.servlet.jsp</groupId>
            <artifactId>jsp-api</artifactId>
        </exclusion>
        <exclusion>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-log4j12</artifactId>
        </exclusion>
    </exclusions>
</dependency>

선언 후, 다시 메이븐 트리를 출력해봅니다.
