콘솔 오류 보고:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-war-plugin:2.1.1:war

원인:war로 설정되었을 때 웹.xml이 있어야 합니다.
해결: 플러그인 구성 속성을 통해 무시할 수 있습니다.
우선spring-boot-dependencies 이pom 파일을 찾아서

<maven-war-plugin.version>3.1.0maven-war-plugin.version>

버전 번호는 3.1.0입니다.
그리고 프로젝트의pom.xml에 추가

<plugin>
    <artifactId>maven-war-pluginartifactId>
    <version>3.1.0version>
plugin>

버전 번호는spring-boot-dependencies의maven-war-plugin-version 버전 번호와 일치해야 합니다.
mvn clean install을 다시 실행하여 포장에 성공했음을 알립니다.
아이디어에서 시작 클래스를 실행하고 성공적으로 시작합니다.하지만

java -jar demo-without-parent-0.0.1-SNAPSHOT.war

 ：demo-without-parent-0.0.1-SNAPSHOT.war 

왜냐하면,maven-war-plugin이 실행되었지만,spring-boot-maven-plugin 플러그인은 실행되지 않았습니다. 이 플러그인은 버전을 지정하지 않았기 때문에 버전 번호를 설정합니다. 여전히spring-boot-dependencies에서 대응하는 버전 번호를 찾습니다:2.0.2.RELEASE

<plugin>
    <groupId>org.springframework.bootgroupId>
    <artifactId>spring-boot-maven-pluginartifactId>
    <version>2.0.2.RELEASEversion>
    <executions>
        <execution>

                <goal>repackagegoal>
            goals>
        execution>
    executions>
plugin>

재실행
mvn clean install ,

mvn clean install
java -jar demo-without-parent-0.0.1-SNAPSHOT.war

성공하다.
마지막 요약:

1）、maven-war-plugin ：
    2.2： WEB-INF web.xml
    3.1.0: web.xml
     ， spring-boot-dependencies maven-war-plugin 。

2）、spring-boot-maven-plugin repackage， spring boot  ， 。

3）、 spring-boot-dependencies
