            <type>pom</type>
        </dependency>
    ...
    

我的

Answer 1

我在我的

plugin

parent

中添加了这个

pom.xml

：

<build>
    <plugins>

        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <configuration>
                <classifier>exec</classifier>
            </configuration>
        </plugin>

    </plugins>
</build>

构建后，所有事情都是正确的
