Maven，继承pom模块

Question

我正在写一个项目，但在编译我的项目时遇到了问题。在我导入了必要的依赖项之后，如pom文件所示，我无法运行该项目。

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">

<artifactId>maven-war-plugin</artifactId>
<configuration>
<failOnMissingWebXml>false</failOnMissingWebXml>
</configuration>
</plugin>
</plugins>
</build>
</project>

它在pom文件上显示的错误如下：

项目构建错误：POM org.springframework.boot:universeBySali-web:1.3.6.RELEASE(C:\Users\User\Deskt\Materiale\Desktop\Java Projects\universeBySali\universeBySali-web\POM.xml(指向com.sali:universeBySali而不是org.springfframework.boot:spring-boot starter父级，请验证您的项目结构

这个pom文件有一个父pom，如下所示：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">

<groupId>com.sali</groupId>
<artifactId>universeBySali</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>pom</packaging>
<modules>
<module>universeBySali-Model</module>
<module>universeBySali-repository</module>
<module>universeBySali-service</module>
<module>universeBySali-util</module>
<module>universeBySali-web</module>
<module>universeBySali-ui</module>
</modules>
</project>

有人能告诉我我做错了什么吗？？感谢

默认情况下，Maven假设父级具有以下relativePath：../pom.xml。Maven将尝试匹配groupId/artifactId/version，如果不成功，将抛出警告并使用"外部"父级。为了确保Maven不会试图将父模块作为多模块的一部分来求解，您应该将<relativePath/>添加到父模块中。
