Maven : 다중 모듈 WAR 빌드가 라이브러리 프로젝트에 "주 클래스를 찾을 수 없음"을 제공합니다.

Tomcat에 전쟁으로 배포해야하는 스프링 부트로 다중 모듈 웹 프로젝트를 개발 중입니다. CLI에 내장 된 바람둥이를 갖고 싶지 않습니다.

프로젝트는 다음으로 구성됩니다.

de.dpt.app-애플리케이션의 주요 부분입니다.
de.dpt.gen-라이브러리 : 엔티티 및 ORM 매핑 (생성됨)
de.shopify.api-라이브러리 : Shopify REST Api 구현

어떤 프로젝트에도 메인 클래스가 필요하지 않습니다. 여전히 "mvn install"을 실행할 때 ..

org.apache.maven.lifecycle.LifecycleExecutionException: 
Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:1.3.5.RELEASE:repackage (default) 
on project de.shopify.api: Execution default of goal 
org.springframework.boot:spring-boot-maven-plugin:1.3.5.RELEASE:repackage failed: 
Unable to find main class

poms가 매우 비슷하기 때문에 'de.shopify.api'모듈이 빌드되지 않는 반면 'de.dpt.gen'은 빌드되지 않는 이유를 이해할 수 없습니다. 도와 줄 수 있나요?

당신은 봄 부팅 chcek 경우 문서를 위해 spring-boot-maven-plugin그것을 말한다

spring-boot-maven-plugin이 pom.xml에 포함되면 자동으로 아카이브를 다시 작성하여 spring-boot : repackage 목표를 사용하여 실행 가능하게 만듭니다.

메인 클래스를 지정하지 않으면 플러그인은 public static void main (String [] args) method를 사용하여 클래스를 검색합니다 .

따라서 "de.dpt.gen"모듈에서이 플러그인은 public static void main (String [] args) 메서드를 갖는 클래스를 찾을 수 있지만 모듈 "de.shopify.api"에는 public 클래스가 없을 수 있습니다. static void main (String [] args) 메서드.

독립 실행 형 실행 파일과 일반 전쟁 배포 가능 둘 다로 실행하려면 parent / pom.xml에 spring-boot-maven-pluginApplication 클래스를 아래와 같이 기본 메서드와 함께 포함하여 명시 적으로 지정할 수 있습니다.
