어떻게하면이 Paven.xml을보다 전문적으로 만들 수 있을까요?

Question

구글 앱 엔진, 구글 웹 툴킷 (플랫폼, gwtp) 및 이클립스로 메이븐을 시도한 것은 이번이 처음입니다. 우리는이 코드를 여기저기서 발견했습니다. 이 POM 파일을 개선 할 수 있을지 궁금해합니다. 특히 빌드 섹션에서 개선 할 수있는 부분이 무엇인지 궁금합니다.

Answer 1

사용자 지정 속성은 훌륭하지만 실제로 사용하기 때문에 사용하지 마십시오. 이를 사용하여 상위 POM에 중복성을 제거하고 관리를 지연시킬 수 있습니다. 그 이외에, 나는 당신의 질문의 범위에 대해 잘못된 것을 보지 못합니다.

Answer 2

대부분의 설정은 모든 gae-gwt-eclipse-maven 프로젝트에 공통적입니다. 따라서 구성을 표준화하는 프로젝트 (예 : gae-gwt-eclipse-base, <packaging>pom</packaging>)를 모두 포함하는 프로젝트를 만들면 실제 프로젝트가 해당 POM을 상속하고 나열한 모든 상용구를 자체에서 제외하게됩니다. 실제로 식별자와 <parent> 섹션을 제외하고는 "이것은 표준 GAE-GWT-Eclipse 프로젝트입니다."라고 선언하게 될 것입니다.

GAE-GWT-Eclipse 프로젝트가 하나뿐이라면 무엇이 공통이고 구체적인 내용인지 확신하기는 어렵지만 모두 똑같이 수행 할 가치가 있다고 생각합니다.

plugins 대신 pluginManagement 섹션에 구성을 추가로 개선하는 것이 좋습니다.

pluginManagement "나는이 플러그인을 사용해야하는 경우, 여기에 내가 원하는거야 구성이다 (나는 그것을 무시하도록 선택하지 않는 한).하지만을 사용합니다 I 을 말하는 게 아니에요"라고 말한다. plugins 섹션에는 "이 프로젝트를 빌드 할 때이 플러그인을 실행하고 싶을뿐 아니라 상속 된 내용이 아닌이 구성을 사용하십시오."라고 표시되어 있습니다.
